Since the shorelines <br />are previously inundated lands, there is the potential <br />f'or additiOnal erosion. <br />Disrupt'waterf'owl nesting areas. The normal riparian <br />zones which traditionally provide protection and covel" f'or <br />the nesting birds will be dried out and the vegetation will <br />be subject to f'ires. <br />Fisheri~s impacts. The water quality of' the streams <br />will deteriorate signif'icantly; municipal sewage treatment <br />outf'alls will represent a higher portion of' the streamf'low; <br />irrigation return f'lows will probably cause a higher con- <br />centration of' total dissolved solids in the streams; and, <br />f'or those a~eas of' anadromous f'ish runs, there will be little <br />water available f'or the operation of' f'ish ladders. In the <br />latter case the Corps of' Engineers (COE), BuRec and the <br />utilities are committed to provide their best ef'f'orts to <br />alleviate this threat to the f'isheries. <br />Reduced water levels will greatly impact recreation <br />and recreation-related f'acilities and structures (i.e. <br />boat ramps, 'docks, water-intakes). The low f'lows will also' <br />increase the temperature throughout the aquatic regime <br /> <br />52 <br /> <br />: :".':' '-:,> -'.,~ <br />. <br /> <br />-.'.-, .' <br /> <br />'':;';';.''."::::;''".
