Flood control: <br />? <br /> <br />Reclamation should consider floodplain management in the Delta area as a flood <br />control alternative. <br />? <br /> <br />Alternatives should not increase fl ows over 10,500 cfs at Delta until flood control <br />improvements made. <br />? <br /> <br />Continuing to provide flood control benefits to Delta was expressed by several <br />commentors as a concern. <br />? <br /> <br />Spring peaks have flood control benefits by keeping the channel open and <br />discoura ging development in flood prone areas. <br />? <br /> <br />Flood plain should be mapped. <br />? <br /> <br />Lowering the flood target (cfs) at Delta could have unintended consequences of <br />reducing Blue Mesa storage and reducing channel capacity of the river at Delta. <br />? <br /> <br />Floodplains in the Delta are a and downstream provide important endangered fish <br />habitat and adequate flows are needed to allow these floodplains to function. <br />? <br /> <br />Upstream icing targets should be revisited. Can existing ice easements or new <br />easements substitute for the winter reservoir ta rget elevations? <br />? <br /> <br />Existing reservoir operations to reduce upstream icing problems should be <br />continued. <br /> <br /> Hydropower: <br />? <br /> <br />Some thought that h ydropower is an inci dental purpose of the Unit and should not <br />direct alternative selection. Others pointed out the imp ortance of hydropower and <br />indicated that alternatives should protect or enhance hydropower production. <br />? <br /> <br />Hydropower revenues are important for CRSP and participating project <br />repayment and for assisting in funding the Recovery Program --- these revenues <br />shoul d be protected. <br />? <br /> <br />Cumulative impacts on hydropower due to operation changes at CRSP reservoirs <br />need to be presented. <br />? <br /> <br />Crystal Dam’s role as a reregulating reservoir should be continued; only Morrow <br />Point and Blue Mesa should be used for peaking. <br />? <br /> <br />Power generat ion model of WAPA should be used in EIS process. <br />? <br /> <br />If there are hydropower los s es, consider re - pricing hydropower to more closely <br />reflect the market value of peaking power so as to offset any economic los s es. <br />? <br /> <br />A lso consider as an alternative a pumped stora ge peaking facility at on e of the <br />reservoirs. This would offset losses and increase flexibility. <br /> <br /> Maintenance: <br /> <br />? <br /> <br />Effect of flow recommendations (spring peak) on the Gunnison Diversion Dam <br />should be analyzed. <br />? <br /> <br />What are long - term maintenance needs for the Unit and how do they fit with <br />alternatives? <br /> <br /> <br />Socioeconomics: <br /> 11 <br />
