This memorandum analyzes the hydrologic impacts of three sets of scenarios of City of Solvang's river well pumping, including: 1. No change from current river well pumping by Solvang (varies roughly from about 400 to 1,000 acre-feet/year in years ) 2. Total river well pumping by Solvang of2,400 acre-feet per year and maximum diversion of 5 cfs per Table 7 of the Water System Master Plan 3. Total river well pumping by Solvang of3,600 acre-feet per year and maximum diversion of 5 cfs per Permit Although the exact alternatives for the Environmental Impact Report (EIR) by the City of Solvang are not completely known, this memorandum analyzes twelve alternatives which overlie the above three sets of Solvang river pumping on four alternatives set forth in the Cachuma Water Rights Draft EIR by the State Water Resources Control Board (August 2003). For each of these twelve potential EIR alternatives, analyses of surface water hydrologic impacts were performed, Stetson Engineers Inc. F:IDATAII944ISURFACEWATERITM SW RESULTS V7.DOC Page I

3 DRAFT using the Santa Ynez River Hydrology Model (SYRHM). Included in this memorandum are the EIR hydrologic impact analyses for: Cachuma Reservoir Operations Cachuma Storage and Elevations Santa Ynez River Flows Groundwater Storage in the Above Narrows Riparian Aquifer Water Rights Releases (WR 89-18) Cachuma Project Deliveries In addition to this technical memorandum, hydrologic analyses for salinity impacts and additional ground-water impacts (including water level changes and possible well interferences) are provided in separate technical memoranda. 2. SYRHM OVERVIEW AND MODELING FOR FISH FLOW OPERATIONS, SURCHARGING, AND SOLVANG RIVER WELL PUMPING The SYRHM became the basis for numerous hydrologic studies of releases for fish, water quality, and water rights in preparation ofthe Biological Assessment, NOAA Fisheries Biological Opinion (BO), the Lower Santa Ynez River Fish Management Plan, the Settlement Agreement of 2002, the State Board Draft EIR (2003), and the Draft EIRJEIS (2003) on the Fish Management Plan and the BO (see references). The analyses for the additional City of Solvang river well pumping use the same programming model logic and assumptions as these previous studies. For example, previous SWRCB EIR modeling analyses assumed that Solvang pumps on average 600 acre-feet per year. Based on 34% return flow consistent with the SYRHM, the net pumping for Solvang was set at 396 acre-feet per year. This pumping amount will be used for the baseline runs to maintain consistency with previous analyses. In all twelve alternatives analyzed in this memorandum, all of the original flow inputs are kept the same, with various combinations of changes in City of Solvang river well pumping, fish flow operations, and surcharging, as shown in Table 1. Each ofthese three Stetson Engineers Inc. F:IDATAI1944ISURFACEWATERITM SW RESULTS V7,DOC Page

The SYRHM was developed by the Santa Barbara County Water Agency (SBCWA). Over the last two decades, the SYRHM has been expanded and modified in consultation with the Santa Ynez River Hydrology Committee. The Stetson Engineers Inc. F:IDATAI1944ISURFACEWATERITM SW RESULTS V7.DOC Page

5 DRAFT model is written in Microsoft Quick Basic code and is publicly available from SBCW A. The SYRHM has been expanded by Stetson Engineers for fish flow operations, surface water salinity, and State Water Project imports (Stetson, 2004). In all of the model runs, watershed runoffbased on historical hydrology is routed through the Santa Ynez River basin and alternatives are varied based on the differences in Cachuma Reservoir operations, State Water Proj ect (S WP) water deliveries, and municipal and industrial pumping by the City of Solvang. The impacts to surface water and ground-water conditions downstream of Cachuma Reservoir and Solvang river wells are then compared among the alternatives. Figure 1 shows how flows ofthe Santa Ynez River are routed through the Santa Ynez River basin. The SYRHM includes operations of Juncal, Gibraltar, and Bradbury Dams, the Santa Ynez River alluvial ground-water basins, and Santa Ynez River recharge (percolation) in Lompoc basin. The model uses historical records of rainfall, runoff, evaporation, and tunnel infiltration for the period 1918 through Reservoir releases, diversions, streamflow percolation, ground-water pumping, and depletions are based on simulated model operations using monthly time steps. The model includes the Gibraltar operations under the Upper Santa Ynez River Operations Agreement, and the Cachuma operations under the SWRCB Order WR as amended by WR As indicated above, the model has been expanded to include fish flow operations, surface water salinity, and SWP water deliveries through the Bradbury Dam outlet works (Santa Ynez River Hydrology Model Manual, April 2004). The model expansion for surface water salinity and the SWP imports was done in consultation with the Santa Ynez River Water Quality Technical Committee. The Santa Ynez River between Bradbury Dam and Lompoc Narrows is divided into three main subunits in the model: (1) Bradbury Dam-Solvang (Santa Ynez subarea); (2) Solvang-Buellton Bend (Buellton sub-area); and (3) Buellton Bend-Narrows (Santa Rita sub-area). Recently, the SBCW A expanded the operation model (SYRHM) to incorporate a detailed version ofthe Bradbury Solvang reach, in which the reach is divided into 12 segments between tributaries. This allows for a direct modeling oftributary flow contributions in the Bradbury Dam-Solvang reach ofthe SYRHM. This version of the model is referred to as SYRHM 498, and was used for the analyses of the Stetson Engineers Inc. F:IDATAI1944ISURFACEWATERITM SW RESULTS V7.DOC Page

6 DRAFT Biological Assessment resulting in the Biological Opinion. The same version ofthe model (SYRHM 498) has been used for the analyses ofthe Cachuma water rights draft EIR. The same version is also used for the impact analyses of the City of Solvang's wells as provided in this memorandum. The City of Solvang's wells are located near Solvang Bridge (also sometimes referred to as Alisal or Mission Bridge), which is right on the boundary between the Santa Ynez and Buellton sub-areas. 2.2 CACHUMA FISH FLOW OPERATIONS Releases from Cachuma Reservoir for steelhead rearing habitat and passage have been modeled for two sets of operating criteria in the SYRHM. Both are derived from the issuance ofthe Biological Opinion (BO) by the National Marine Fisheries Service (NMFS) (Sep. 2000) and the Lower Santa Ynez Fish Management Plan (FMP) (Oct. 2000). The first set of operating criteria involves releases for steelhead rearing associated with the interim phase, as outlined in the BO and FMP. The interim phase of Cachuma fish flow operations is occurring currently. The second set of operating criteria involves releases for steelhead rearing and passage associated with the final phase (long term) as outlined in the BO and FMP. One element that is common to both sets of the fish release operating criteria is the conjunctive operation of water rights releases with fish releases. This conjunctive use operation would extend the period of time each year when instream flows improve fisheries habitat for oversummering and juvenile rearing within the mainstem river. Interim (present-condition) flow targets in the Santa Ynez River at the Highway 154 Bridge are shown in Table 2. Stetson Engineers Inc. F:IDATAI1944ISURFACEWATERITM SW RESULTS V7.DOC Page

October 2, 2000, pg In years when Cachuma Reservoir spills 20,000 acre-feet or more, a target flow of 5 cfs will be maintained at the Highway 154 Bridge. In years when Cachuma Reservoir does not spill or spills less than 20,000 acre-feet, the Highway 154 target flow will be determined at the start of each month based on reservoir storage: 2.5 cfs when storage is greater than 120,000 acre-feet and 1.5 cfs when storage is less than 120,000 acre-feet. Periodic releases to refresh the Stilling Basin and Long Pool will be made when storage is less than 30,000 acre-feet. In addition, the BO requires a 2 cfs minimum flow in Hilton Creek once a pump is installed as a part of the terms and conditions to implement Reasonable and Prudent Measure No.2 ofthe Biological Opinion. Also, both the BO and FMP under the interim phase include a provision that the U.S. Bureau of Reclamation (USBR) shall maintain residual pool depth in Alisal and Refugio reaches downstream of the Highway 154 Bridge during spill years and the first year after spill years if steelhead are present. Because the quantity of water needed to maintain residual pool depth has not yet been determined and is necessary only when steelhead are present, this provision has not been included in the SYRHM.

In years when Cachuma Reservoir does not spill or spills less than 20,000 acrefeet, the Highway 154 target flow will be determined at the start of each month based on reservoir storage: 5.0 cfs when storage is greater than 120,000 acre-feet and 2.5 cfs when storage is less than 120,000 acre-feet. Periodic releases to refresh the Stilling Basin and Long Pool will be made when storage is less than 30,000 acre-feet. In addition, the BO requires a 2 cfs minimum flow in Hilton Creek once a pump is installed as a part of the terms and conditions to implement Reasonable and Prudent Measure No.2. Also, both the BO and FMP under the final phase the USBR shall provide a target flow of 1.5 cfs at Alisal Road Bridge in years with spill greater than 20,000 acre-feet and the first year after such spill years if steelhead are present. In addition, under the final implementation phase of the BO and FMP, specific volumes of water are dedicated for the "Fish Passage Account" (3,200 acre-feet) and for the "Adaptive Management Account" (500 acre-feet) for a total of3,700 acre-feet. The water in these two accounts is allowed to carry-over from one year to the next; however, the accounts are deemed to spill first Stetson Engineers Inc.

9 DRAFT and are then reset to their maximum amount of 3,700 acre-feet. Water in the passage account is planned to be used to supplement storms by augmenting the descending limb of the storm hydro graph below Bradbury Dam. Table 4 lists some ofthe passage supplementation criteria which were incorporated into analyses for the Biological Opinion and Fish Management Plan. TABLE 4 PASSAGE SUPPLEMENTATION CRITERIA Passage releases will be made in years following a spill until accounts have run out Passage releases will only occur January through May. Passage releases will only occur during a storm and there is continuous flow to the ocean. Santa Ynez River at Solvang reaches 25 cfs during a storm 1 51 Storm in January may not be supplemented Cachuma releases through outlet works based on matching Cachuma inflow decay curve and boosting storm peak to 150 cfs at Solvang The modeled fish releases for rearing and passage in these analyses for the City of Solvang use the same model programming code for releases for steelhead rearing habitat and passage as used in previous model runs for the BO, FMP, and SWCRB draft EIR and are completely compatible. 2.3 CACHUMA RESERVOIR SURCHARGING AND MAXIMUM STORAGE CAPACITIES The Cachuma Lake bathymetric survey of year 2000 (MNSCE, Oct. 2000) shows that Cachuma Lake capacity at elevation feet msl is 188,035 acre-feet, a reduction of2,374 acrefeet from the year 1989 survey capacity of 190,409 acre-feet. Table 5 shows the maximum surface elevation and storage capacity associated with various surcharge quantities based on the 2000 survey for the alternatives listed in Table 1 of 0, 0.75, and 3.0 feet. Currently, Cachuma reservoir is surcharged 0.75 feet above the historical maximum elevation of feet. Stetson Engineers Inc. F:IOATAI1944ISURFACEWATERITM SW RESULTS V7.00C Page

Typically, urban areas have a higher municipal return flow percentage (>50%) while more rural areas have a lower municipal return flow percentage. This analysis uses a municipal return flow of 34% consistent with the SYRHM. This estimate roughly matches estimates by the SBCW A in 1991, which examined return flows from each water purveyor in the basin and determined that 4,485 acre-feet, or 32%, of 14,016 acre-feet of water produced returned to the basin for reuse. In 1992, Stetson Engineers estimated municipal return flows of 30 percent for ID #1 and 40 percent for the City of Solvang (Stetson, 1992). In addition, the municipal return flows in the SYRHM are assumed to return within the same month. Table 6 shows both the net and gross pumping by the City of Solvang used for these analyses, including the three scenarios of City of Solvang's gross pumping from the Santa Ynez River wells of 600; 2,400; and 3,600 acre-feet per year. The three scenarios also correspond to current pumping, four times current pumping, and six times current pumping, respectively. The annual pumping of 600 acre-feet represents the average amount of water pumped from the river wells by the City of Solvang in years 2000 (787 acre-feet) and 2001 (465 acre-feet). The City of Solvang Water System Master Plan Update (Table 7, Provost and Pritchard, May 2002) provides the proposed river well pumping and represents the buildout condition of2,400 acre-feet Stetson Engineers Inc.

12 DRAFT per year. The monthly percentage of annual demand in the Water Master Plan is based on 2000 and 2001 seasonal demands, and the river well volume represents the amount of water needed from the Santa Y nez River underflow to meet average day demand. The net pumping amounts corresponding to the increased Solvang gross pumping of2,400 and 3,600 acre-feet are used in the model analysis. The SYRHM assumes that the well yields for these increased pumping scenarios would not decrease even during critical droughts, so these analyses are considered conservative. 2.5 MODEL LIMIT A TIONS OF THE SYRHM The intended use ofthe SYRHM is for comparative purposes between the EIR alternatives. The simulated flow data generated from the SYRHM is not meant to be predictive, but to be used as an analytical tool for statistical and comparative purposes. Since the model is used for comparative analyses, some of the inherent inaccuracies in the model are expected to cancel out when comparing the results of one scenario with another. The SYRHM operations have some limitations because the model uses monthly time steps. Other limitations of the SYRHM are related to real time management decisions. For example, WR89-18 releases, project delivery reductions in times of shortages, and SWP deliveries could vary based on real time management decisions. Stetson Engineers Inc. F:IDATAI1944ISURFACEWATERITM SW RESULTS V7.DOC Page

13 DRAFT 3. SYRHM OPERATIONAL MODELING RESULTS 3.1 CACHUMA RESERVOIR OPERATIONS The surface water budget for Cachuma Reservoir for all ofthe alternatives is shown in Table 7 for the hydrologic period Table 7 shows that on average over the hydrologic period, the amount of water passed through at Bradbury Dam, either by spills and leakage, water right releases, and fish releases, is relatively the same (less than 1 % variation l ). In summary, the major changes to the Santa Ynez River flow system due to changes in Cachuma Reservoir operations are that when there are more low flow releases, such as for water rights or releases for fish, there are fewer spills or high flow releases. The first four columns (Alternative Nos. 1-4) in Table 7 show that the water to be used for steelhead rearing and passage releases under the interim phase (Alt 2) and final phase (Alts 3A and 3C) of the BO comes not just from the surcharge (i. e., reduction in spills) but also from a reduction in water right releases and Cachuma Project deliveries. Table 7 shows that water right releases, on average, are reduced significantly under the fish release alternatives (Alternative Nos. 2, 3, and 4) when compared as a percentage of water right releases without fish release requirements (Alternative No.1). Project deliveries are reduced the most during critical drought periods, as discussed in a later section of this memorandum. Table 7 shows that the largest difference in Cachuma Project operations for increased Solvang river well pumping scenarios (Alternative Nos. 5-12) is an increase in water rights releases. For example, under Alt 3C with fish flow operations and surcharge, the difference in water rights releases is about 540 acre-feet per year between Solvang river well pumping scenarios of 600 afy (Alternative No.4) and 3,600 afy (Alternative No.8). The increase in water rights releases from Cachuma 1 Note: The precipitation and evaporation vary for each of the EIR alternatives due to differences in the surface area of the reservoir. Also, Tecolote Tunnel infiltration is not shown on these tables but is considered a component of the Project yield. Tecolote Tunnel infiltration averages about 2,050 acre-feet/year for the period and 1,620 acre-feet/year during the drought period Stetson Engineers Inc.

15 DRAFT Reservoir with increased Solvang pumping is due to an increase in water production and associated increase in the total dewatered storage levels, which affect the Above Narrows Account. Fish flow operations are about the same when Solvang increases well pumping because (1) the primary management reach for fish flows is the Highway 154 reach, located about seven miles upstream of the City of Solvang river wells; (2) the increase in water rights releases conjunctively decreases the flows needed for fish; and (3) the number of spill years greater than 20,000 acre-feet, which triggers fish flow targets at the Alisal Bridge, is reduced. Figures 2a-b and 3a-b show the frequency of releases and spills from Cachuma Reservoir for all alternatives on different scales of flow. Figures 2a-b indicate that flow distribution frequencies under the various alternatives in terms of high flows are nearly similar. Figures 3a-b show the differences among the alternatives for flows less than 50 cfs. The alternatives with fish flow operations (SWRCB Alternatives 2, 3A, and 3C) show higher rates and longer duration in flows between 0 and 10 cfs. The alternatives with increased Solvang river well pumping (Alternative Nos. 5-12) show higher rates and longer duration in flows between 10 and 50 cfs. 3.2 LAKE STORAGE AND ELEVATION The minimum storage level (minimum pool) is set to 12,000 acre-feet, which occurs during the critical drought of for all alternatives. Table 8 summarizes average Lake Cachuma elevation and storage for each alternative. In general, the median elevation, storage, and surface area for all alternatives are very similar.

17 DRAFT 3.3 SANTA YNEZ RIVER FLOWS7 Figures 4a-b through 9a-b show the frequency of flows at six different locations downstream of Cachuma Reservoir for the various alternatives based on the results of the SYRHM. Figures 5a-b and 6a-b illustrate the key differences among the increased Solvang river well pumping scenarios. Figures 5a-b show the frequency of flows of the Santa Ynez River at the Highway 154 Bridge, in which Solvang increases in river well pumping result in little change. Figures 6a-b show the frequency of flows of the Santa Ynez River at the A1isa1 Bridge, in which the differences in flow between pumping scenarios are more apparent. Figure 6a indicates that Alt 3C/2400 afy (shown in green), produces low flows over a greater frequency than the present conditions, Alt afy (shown in blue). Figure 6b shows the lowest flows at Solvang Bridge occur for the Alt afy scenario. Appendix A contains the monthly flows for the twelve alternatives from 1918 through 1993 (912 months). Table 9 compares the mean annual stream flows at key sites downstream ofcachumareservoir. The mean or average statistic differs from the frequency graphs in that this statistic can be influenced by infrequent, extremely large storm events. For example, fish flow operations in Alt 3A and Alt 3C are the same except that Alt 3C has a surcharge to 3.0 ft and fewer spills, so Alt 3C's average annual flows are slightly smaller than 3A. For the scenarios of increased Solvang river well pumping, mean annual flows at Highway 154 bridge are similar. However, the Santa Ynez River mean annual flows at the Alisal Bridge and Lompoc Narrows are reduced by 532 to 1,735 acre-feet per year in the scenarios with increased Solvang pumping (Alternative Nos. 5-12). Tables loa-c also show the median monthly flows at the Highway 154 Bridge to be similar, and the median monthly flows at Alisal Bridge and Lompoc Narrows to be less for the increased Solvang river well pumping scenarios.

22 DRAFT 3.4 GROUNDWATER STORAGE IN THE ABOVE NARROWS RIPARIAN AQUIFER During the low flow periods, there is more percolation into the Above Narrows Riparian Aquifer in the scenarios with releases for steelhead. Figures 10A-C show the changes in total dewatered storage in the entire Above Narrows Riparian Aquifer. These figures show less total dewatered storage during low flow periods when there are more fish releases. An opposite effect is that there is more total dewatered storage when Solvang river well pumping increases. As shown in Figure loa, the Above Narrows Riparian Aquifer recovers to the same levels with the recharge of winter runoff under the various alternatives. The key differences in water levels between the alternatives occur during the droughts. For the purposes of comparison, Figure lob shows that Alt 3A afy (shown in red), results in slightly more dewatered storage levels in the Above Narrows Aquifer than Alt 3A1 600 afy (shown in blue). This difference is due to the increased Solvang river well pumping. Figure lob shows that there is only a very small to no difference between Alternatives 3A and 3C on groundwater storage in the Above Narrows Riparian Aquifer. Figure 10C shows that the largest dewatered storage levels would occur for Altll 3600 afy (shown in red). Figures 11A-C, 12A-C, and 13A-C show the effects to total dewatered storage for the three different sub-units ofthe above Narrows riparian aquifer, the Santa Ynez, Buellton, and Santa Rita sub-basins. The greatest effect is on the Santa Ynez sub-basin. Tables 11 through 14 show statistics on monthly total dewatered storage for the Above Narrows Riparian Aquifer and for the three different sub-units. For comparison, the last four columns show the difference in dewatered storage relative to Alternative 2 (present conditions). For example, Table 11 shows that Alt 3CI 2400 afy (Alternative No. 12), results in 219 acre-feet more dewatered storage on a median basis than the present conditions, Alt afy (Alternative No.2). The average decrease in dewatered storage due to fish releases (Alternative Nos. 3 and 4) reverses to an average increase in dewatered storage under higher Solvang river well pumping scenarios (Alternative Nos. 5-12) when compared with present conditions (Alternative No.2). The increase in dewatered storage levels shown in Table 11 for the Solvang river well pumping scenarios would Stetson Engineers Inc. F:IDATAI1944ISURFACEWATERITM SW RESULTS V7.DOC Page

27 DRAFT affect WR89-18 releases from Cachuma Reservoir. Tables 12 through 13 show that this impact on groundwater storage is larger in the Santa Ynez sub-unit; which is the sub-unit closest to Bradbury Dam and also includes Highway 154 and Alisal Bridge, which are the fish releases' target sites, and is the sub-unit in which Solvang river wells are located. Tables 15 through 18 show the impact of the EIR alternatives on the average water level elevations in the Santa Ynez, Buellton, and Santa Rita sub-basins of the Above Narrows Riparian Aquifer. Relationships developed by Reclamation between groundwater storage and groundwater elevation were used to develop the relative changes in depths to water for various alternatives, with values being rounded to the nearest foot. The most significant change among the EIR alternatives occurs in the Santa Ynez subarea, with water levels in the groundwater decreasing one to five feet on average. The largest differences occur during droughts. Table 15 indicates that Alt 3CI 2400 afy (Alternative No. 12), results in water levels in the Santa Ynez sub-area five feet lower during the critical drought period than under the present conditions, Alt afy (Alternative no. 2). The SYRHM is limited in predicting water level changes beyond the large groundwater subunits of Santa Ynez, Buellton, and Santa Rita because it does not take into account aquifer properties. Stetson Engineers is performing a more detailed analysis using a numerical groundwater model to determine the local changes in groundwater levels due to increased Solvang river well pumping.

31 DRAFT 3.4 WATER RIGHTS RELEASES (WR 89-18) Table 18 shows the impacts to water rights releases for the various alternatives as determined by the SYRHM. The Above Narrows Account is dependent upon groundwater storage in the Above Narrows Riparian Aquifer because the account can not be larger than the dewatered storage. Table 18 indicates that WR89-18 releases would be increased as a result of increased pumping by Solvang. For example, the average annual release would increase by about 300 acre-feet under Alt 3C/ 2400 (Alternative No. 12) when compared to Alt 3C/ 600 (Alternative No.4).

32 DRAFT 3.5 CACHUMA PROJECT DELIVERIES Shortages in water supply from the Cachuma Project during droughts are determined using SYRHM. The historical precipitation at Gibraltar Dam from 1947 through 1951 was 35% to 60% below normal. The shortages to water supply during the last three years of this critical period for the various EIR alternatives are shown in Table 19.

During the last three years of the critical period ( ), a cumulative shortage of approximately 5,900 acre-feet would occur between present conditions Stetson Engineers Inc. F:IDATAI1944ISURFACEWATERITM SW RESULTS V7.DOC Page

33 DRAFT (Alternative No.2) and historical conditions (Alternative No.1). In the worst year of the critical period, a reduction in yield of2,740 acre-feet would occur. Alt 3C/ 2400 afy (Alternative No. 12), increases these already large shortages by an additional 1,380 acre-feet in the last three years ofthe critical period. This increase in project shortages in critical droughts is the result of the increased water rights releases due to the increase in Solvang's river well pumping. Similarly, Alt 3C/ 2400 afy (Alternative No. 12) would increase the project shortage by about 570 acre-feet in critical drought year (1951) when compared to Alt 3C/ 600 afy (Alternative No.4). It is also important to note that the shortages just described are in addition to shortages in available water supplies that would occur under WR89-18 Cachuma operations during the historical drought condition. The Cachuma Project members, which include the City of Santa Barbara, Goleta WD, Montecito WD, Carpinteria CWD, and SYRWCD ID No.1, all share the shortages. Stetson Engineers Inc.
