minimum condition would have virtually no effect on the flow in the lower American River. Under "~laximum Conditions", diversion by EBMU~ to meet the maximum condition (i.e., 150,000 AFA) would have a relatively minor effect on the level of flow in the lower American River, EBHUD's proposed diversion would reduce the average flow during the peak runoff period (February to june) to an average flow of about 4,000 cfs. During the low flow period, EBMUD's proposed diversion would reduce the flow in the river about once each ten- years. IMPACT OF PUBLIC TRUST VALUES IN THE LOWER AMERICAN RIVER EBMUD's proposed diversion will have minor effect on the public trust us.'s ma~=_ of the lower American River,-even under the "maximum" condition describe~ above, Release of water from Folsom Reservoir and other upstream reservoirs has enhanced flow in the lower American River during the past 30 years. At the present, the su~rner flow is about 6 times higher than the flow that existed prior to the construction of Folsom Reservoir. The higher flow, coupled with the development of the American River Parkway, has resulted in greater public use of th.= river. The water flowing down the lower American River supports a wide variety of instream resources and uses including fisherlos, rioarian vegetation, wildlife, fishing, boating, wading, swinning, nature study, and scenic ~alues. The Board has evaluated the effect that EB~iUD's proposed diversion would have on public trust uses in the lower American River. This evaluation is based on the Board's hydrology studies for the "minimum" and "maximum" conditions described above. 10
