3 100 bodies of water within the State. Supplemental warmwater fish and fish eggs must be obtained from other sources. . Colorado's fish production facilities are continuously being ex- panded withi'n the limits of State funds. Unfortunately, the need for hatchery, fish to stock Federal reservoi rs, such as Narrows Reservoir, is increasing faster than funds and Federal assistance to meet these needs. The fish production site which has been investigated by the Colorado Division of :Game, Fish and Parks would consist of about 120 acres located just downstream of the proposed Narrows Dam in Section 17, 18, and 20, ,Range 58 West, Townsh i p 4 No rth. The hatche ry site 1 i es within the proposed project takeline on lands within the area re- quested for recreational development by the National Park Service. R<<cre.ational use at the hatchery would be coordinated with and would be compatible with the recreation plan proposed by the National Park Service. No additional land would need to be acqui red for the hatchery. The unit would be a combination warmwater and coldwater hatching and rearing unit which would produce fry and fingerl ings to stock project waters. The entire output of the unit would be used in project waters of the Narrows Unit. Because of geological formations, seepage from Narrows Dam is ex- pected to be 20 second-feet when the reservoir is at minimum pool and about 8Q second-feet when the reservoi r is full. Temperature of the seep 'water is expected to be about the same as ground water in the area; or approximately 550 F. The water quality of several wells in the area indicates that the water would be suitable for fish production. Project plans include the collection of seep water by a series of toe drains in the dam. A 36-inch drain conduit would collect and dis- charge the water into a holding tank just downstream of the dam. Water for the hatchery would be taken from the bottom of the tank via a pressure j:lipe capable of carrying 20 second-feet of water with a 20-foot head. An overflow pipe would be installed near the top of the tank to ,return surplus water to the river. The pressure pipe would transport the water from the dam to the aeration pond where it could be aerated or bypassed to the raceways and rearing ponds. Separate pipes would carry water from the aeration pond to the basin house and to the raceways. When Narrows Reservoi r is low, it may be necessary to supplement water drainIng from the right abutment with water draining from <<
