<br />~ <br /> <br />OOQ358 <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 1 1973 <br />7,[05 1 1973 <br />7.108 1 1973 <br />7.110 I 1973 <br />7.113 I 1973 <br />7.1 [6 1 I [973 <br />7.1 [7 I I [973 <br />7.12[ I [973 I <br /> i i <br />7.123 I I I [973 <br /> I <br />7.126 I I I 1973 <br />7.131 I [973 <br />7.133 I J I 1973 <br /> , <br />7.136 11 I 1973 <br /> I <br />7.137 I I 1973 <br /> I <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 I. 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 />14 <br />
