<br />000749 <br /> <br />According to Nehring (1998), critical time periods for brown trout spawning, incubation and <br />hatching are October 15th through May 15th. Rainbow and brown trout spawning habitat is <br />located downstream of Crystal Reservoir, <br /> <br />Reservoir Elevation Frequency (in days) Year(s) <br />7,102 2 1973 <br />7,104 I 1973 <br />7,105 I. 1973 <br />7,108 I 1973 <br />7,110 I 1973 <br />7,113 1 1973 <br />7,116 I 1973 <br />7,117 1 1973 <br />7,121 I 1973 <br />7,123 1 1973 <br />7,126 I 1973 <br />7.131 I 1973 <br />7,133 I 1973 <br />7,136 I 1973 <br />7,137 I 1973 <br />7,138 1 1973 <br />7,139 1 1973 <br />7,141 3 1973, 1996 <br />7,142 2 1996 <br />7,143 4 1995,1996 <br />7,144 45 1973,1975, <br /> 1995-2001 <br /> <br />Table 1- Reservoir Elevation Frequency (7,102-7,144 ft.) <br /> <br />Brown and rainbow trout may be affected by the proposed action if significant sediments are <br />transported and deposited in key spawning areas downstream of Crystal Reservoir during critical <br />time periods, This could result in eggs laid in redds (nests) being covered with fine silts and <br />deprive the eggs of oxygen. Large amounts of transported sediments could greatly reduce <br />rainbow and brown trout recruitment. <br /> <br />13 <br />
