<br />~ <br /> <br />OJJ8{3 <br /> <br />Conclusions: <br /> <br />Under the No Action Alternative, Reclamation would not remove about 11,000 cubic yards of <br />gravel and deposited material from the upper end of Crystal Reservoir below the Morrow Point <br />Powerplant tailrace. The deposited material would continue to create a pool of water trom the <br />Cimarron River to Morrow Point Dam's stilling basin. Morrow Point Dam's generator power <br />efficiencies would continue to be reduced, Power efficiency losses are estimated at 1.14%. <br />which represents about 5,608 megawatt hours per year at a value of about $98.539.00 per year in <br />power revenues, This would not meet the need and purpose as described above, <br /> <br />In terms of environmental consequences of implementing the proposed action, there will be no <br />change in water use or diversions. In addition, water rights, wetlands, endangered species, power <br />generation (hydropower produclion at Morrow Point and Crystal Reservoirs). cultural resources. <br />Indian trust assets, and environmental justice will not be affected by the recommended action. <br />Overall power system generation will not be directly affected during the dredging period, but <br />completion of the proposed project will improve efficiency in power generation al the Morrow <br />Point Powerplanl. <br /> <br />Impacts will be reduced by restricting the construction period between October \;0 and November <br />30'" to avoid or reduce potential etTects to rainbow and brown trout spawning below Crystal <br />Reservoir and recreational uses (rafting. fishing, guide services), If dredging is not finished in <br />200 I (i,e. inclement weather conditions), additional dredging may occur in October and <br />November 1002, <br /> <br />Dredging activities will be restricted to a six hour period each day when no water will be released <br />from Morrow Point Dam. This will aid in dewatering the dredging site and reduce the potential <br />for increased suspended sediments in the Gunnison River below Crystal Reservoir. Dredged <br />material will be made available to the Colorado Department of Transportation (CDOT) for use in <br />road maintenance, CDOT will stockpile dredged material at an existing CDOT gravel slockpile <br />site, <br /> <br />Water quality will be monitored monthly prior to implementation of the dredging projecl. <br />Initially, water quality samples will be taken daily at the construction site to record ambient air <br />temperature, water temperature. pH, conductivity, total dissolved solids, total suspended solids, <br />calcium, magnesium, total hardness, and dissolved oxygen, If no significant changes in water <br />quality are observed, Reclamation may change the water quality sampling from daily to weekly <br />during the dredging activity. In addition, daily visual observations of Cryslal Reservoir and <br />Gunnison River below Crystal Reservoir will be made. If the Gunnison River below Crystal <br />Reservoir becomes turbid (cloudy) as a result of dredging activities. dredging activities will be <br />stopped, Once the reservoir began to clear, dredging activities will resume. <br />
