John Stroh , SJ1AD , and I inspected the City of Escalon ' s treatment facilities on 12 April 1985 . The City of Escalon ' s facilities consist of several evaporation- infiltration ponds located on the north bank of the Stanislaus River about five miles downstream of the McHenry Avenue Bridge. The ponds receive industrial waste during the processing season via the City ' s storm drawn system. During the rainy season the storm drain is open to the Stanislaus River. The storm drain' s outfall is located east of pond #43 . Drainage is carried to the Stanislaus River via a small drainac?e canal constructed by SJMAD. Diversion of discharge either to the ponds or to the outfall is controlled by a manually operated gate valve located near pond #43 . At the time of inspection , discharge was directed to the storm drain ' s outfall . The entire length ( 300 ' ) of the canal had a very offensive septic odor. Production of gas bubbles from the sediment indicated an active anaerobic laver . Large patches of reddish benthic organisms were noted, possibly tubifex worms or nematods although a positive identification was not made. fir. Stroh stated that all the mosquito fish planted in the canal had died. PREVIEWED BY: }
