<br />OG~l5t)S <br /> <br />10 <br /> <br />d. the effects of temperature, including seasonality and degree, on <br />Cladophora and associated diatoms, Gammarus, and aquatic insects. <br />(RPM l.B.iii, l.B.iv, l.C.i and l.C.vii) <br /> <br />IN 5.4 Evaluate effects of withdrawing water on the heat budget of Lake Powell, <br />effects of potentially warmer inflow into Lake Mead, and the concomitant <br />effects on the biota within both reservoirs. Evaluate the temperature profiles <br />along with heat budget for both reservoirs Evaluate effects of reservoir <br />withdrawal level on fine particulate organic matter and important plant <br />nutrients to understand the relationship between withdrawal level and <br />reservoir and downstream resources. (RPM l.B.vand l.B.vi) <br /> <br />IN 5.5 Evaluate when to release warmer temperature water, what seasonal pattern of <br />releases to use to avoid establishment of permanent backwater areas, and how <br />best to use floods, to limit expansion or invasion of non-native fish species. <br />(RPM IB) <br /> <br />MA 5.2 Develop a management plan for the LCR to protect HBC spawning <br />population and habitat. <br /> <br />MO 6: Establish a second spawning aggregation ofHBC downstream of Glen Canyon Dam <br />(RPM 4). <br /> <br />IN 6.1 Develop criteria for defining self-sustaining populations ofHBC. <br /> <br />IN 6.2 Assess feasibility of establishing a second population of HBC downstream of <br />Glen Canyon Dam including other current aggregations. <br /> <br />MA 6.1 Develop and implement, as appropriate, a plan for establishing a second <br />population of HBC. <br /> <br />RAZORBACK SUCKER (RBS) <br /> <br />MO 7: Remove jeopardy for the Razorback Sucker in the Colorado River ecosystem. <br /> <br />IN 7.1 Determine opportunities to establish RBS in the Grand Canyon (e.g., possible <br />development of spawning and rearing areas).
