001074 Final Environmental Assessment-Chapter 2-Alternatives a) Secure a fIrm supply of water b) Agreement among Ute Water, Orchard Mesa Irrigation District (OMID), Grand Valley Water Users Association (GVWUA), and Reclamation to deliver water to the Ute Water pump plant. c) Execute a 'power interference' agreement among the Recovery Program, Reclamation, OMID, GVWUA, and Xcel Energy to compensate for lost power revenues. Ute Water would divert about 15 cfs from the 800 cfs Orchard Mesa Power Canal, which would decrease the ability to deliver water to the Grand Valley Power Plant. d) Execute a crossing agreement with CDOT for a pipeline through the Rapid Creek culvert under Interstate 70. 2. Lower the sump (submerged pump) in the Ute Water pump plant. Reclamation estimates this option would cost about $600,000, and would require the following: a) Extend the foundation of the pump plant down 6 feet. b) Extend the intake structure and trash rack down 6 feet. c) Extend the discharge piping d) Modify or replace pumps to allow for pumping from a lower elevation 3. Modify the river channel to assure an adequate water surface elevation during low flow conditions. Reclamation estimates the cost of this option at about $1,000,000 (due to the lack of construction access and the magnitude of Colorado River flows). This option would involve constructing a low head dam immediately downstream from the Ute Water pump plant. The dam crest would be about 100 feet-long, and the dam foundation would extend down into the riverbed. The dam design would permit upstream fish passage in a manner similar to the riffle-pool design used at the GVIC Diversion Dam. Other options for protecting the Ute Water pump plant intake were to costly too consider further; 1) acquire alternate water sources, possibly from the Rapid Creek drainage; and 2) construct a new pump plant at a different location. Construction Removal of the Price-Stubb Diversion Dam would be completed under a construction contract. Approval of the owners of the dam would be required. Temporary construction easements or pennits would also be required before construction. Reclamation would negotiate protective measures to reduce impacts to private property, rights-of-ways, and facilities. Following construction, any damaged area would be restored, as near as practicable, to its original condition. Access to the dam would be from Old Highway 6 along a trail that lies within the railroad right-of-way and the E.R. Jacobson property. Construction staging and material storage would be on adjacent vacant land owned by E.R. Jacobson. Construction access is limited near the dam because of its proximity to the railroad tracks and Interstate 70. 21
