Finger Rock Rearing Unit The nature of this unit's water supply and dirt ponds would make it very difficult to rid the facility of WD. In the past, some work by our Engineering Section was conducted on exploring the use of a thermal aquifer in the area. The unit could possibly be cleaned up if another water source and/or disinfection of the present springs could be performed, along with using only concrete raceways. The location of the facility could lend itself to the possibility of using some of the ponds as an angler education area. Glenwood Springs Hatchery Continue to use unit in its present capacity--rood unit, egg station, and subcatchable production. Mt. Ouray Hatchery Refer to discussion below section on Mt. Shavano. Mt. Shavano Hatchery If river water were eliminated and Mt. Shavano and Mt. Ouray were operated only on spring water, the life cycle of WD could be broken and the units could potentially become negative (NOTE: Mt. Ouray is now considered negative with a third negative inspection in May 1996). The two units could then operate on 5-10 cfs of "clean" water and produce 400,000 catchables (approximately half of what they are presently producing). The subcatchable numbers would remain at the current level. With a change in water rights, dependent on the city/DOW land exchange, clean spring water could be enhanced by a factor of two. This would involve using the gravel pit above the hatchery to filter river water, which would eventually trickle back into the unit's spring line free of WD spores. The complex is centrally located for economical stocking throughout the state. Pitkin Hatchery The superintendent believes that with modifications to four raceways (work being completed this summer), along with an attempt to increase fish numbers in the present ponds, production at this WD- hatchery might be increased by another 100,000 catchables. Poudre Rearing Unit This unit is a unique facility because it is located on a "wild and scenic" river that receives a tremendous number of visitor uses each year. If this WD+ unit is not continued at full production, then some options or combination of options might be to 1) use it as a cost- effective planting base for the immediate area; 2) use some of the ponds for WD research; 3) because of the high use in the area, develop a self-guided visitor's center, based on the high use in the area, concentrating on DOW activities in the valley and WD research; or 4) develop some of the ponds for senior citizen and/or disability fishing (possibly with the aid of LOCO funds). 40
