2 TWENTY-SEVENTH ANNUAL REPORT Part Four LEWSTON-AUBURN GENERAL DATA 1969 ntrgdyction. During most of the summer air and water conditions, due to pollution, were more favorable than in 196. River flows were large and fewer temperature extremes were recorded. There were no fish kills observed or reported in the Lewiston area. Daily Repprt!. Daily reports numbered one to ninetyone contain a reoord oft a. River odor. type and intensity b. Air temperatures c. General weather conditions d. Direction of wind e. Surfaoe appearance of the river f. Conditions at Gulf sland and Deer Rips Dams (Frequent but not daily.) These reports were mailed to Messrs Webber, Cooper and Stevens, at frequent intervals, iver Odor. Types tc. Pig-pen odor was dominant in the Pool from Mile Two northward and frequently observed in the region of the Dams. Hydrogen sulfide odor was prevalent in the Mile One area apd very noticeable at the Dams during the last three weeks in July, when the holiday shutdowns and other abnonnally large discharges of pollutants arrived. ef Part three of this report.

3 River odor was reported in the downtown area on eleven days during the season. The flow over the Lewiston Falls (known as Great Falls) was much more frequent than in recent years. The majority of the odor observations was in the North Bridge area. On July )0 hydrogen sulfide was detectable on the bridge and for about a hundred yards up Main Street. On August first the odor was recorded as Musty-Mouldy #2. Pig-pen odor was present on four days and was very noticeable on June seventeen. River odor has not been detected in the downtown area since August six. Air Temperature$. Mean hourly temperatures were above the eighty-five year average during June, August and September and below during July. The temperature pattern was very different from that of 196t! season.

6 River Flows. River flows were much above the thirtytwo year average during May through September; flows during May and August were almost twice as high as the long range average. The high level (99%) of upstream storage after the heavy rains (July 28.Aug.2) made possible the augmentation of natural river flow during the entire month of August and September. TABLE #4 Average Dail t Flows (c,f.s.) (Gulf sland Dam) Year May June July Aug. Sept. J.A.S. average a year aver Rl l ver Surface Foam was somewhat less persistant this Conditions. year, probably due to greater dilution of the Kraft soaps and other detergents. However, large river flows resulted in more spilling over dams and larger areas of foam than were present in 1968 Floating water vegetation was conspicuous by its absence. Blue-green algae were seldom observed and then only on very small pieces of slimy sludge. Dissolved oxygen content of the river water was much larger than last year mainly due to the increase in flows. The lowest dissolved oxygen recorded during the season in Lewiston downtown,
