Fish escapement from Lake Meredith has been a problem; outlet restructure could be a solution to this. 3. General Issues - . Selenium, nutrients and suspended solids are the main issues of concern along the Arkansas River to the CDOW. · The Fish and Wildlife service has recently proposed a limit of I to 2 j.lgIL for a national upper limit of selenium in rivers, lakes and reservoirs. 4. Turquoise Reservoir Enlargement - . Greenbacks are found above Turquoise Reservoir although the inundation from this project would not affect them it is an issue to be aware of. · Inundation in this area may cause problems with Elk caving grounds or migration patterns, this is an issue to follow up on. · Water deliveries could be made through the Otero pipeline or the mainstream of the Arkansas River. The Otero pipeline option may be a benefit to the fish. . The timing of flows and releases would need to be coordinated with the life cycle needs of the Brown Trout. . A decrease in White Suckers and Lake Trout in Twin Lakes has recently been observed. 5. FrvingDan Arkansas ReoDeration - · The affects of this project would most likely consist of more water being stored in Turquoise Reservoir, Twin Lakes and Pueblo Reservoir and the possibility of increased flow in the Arkansas River. · Nitrate levels in the Arkansas are high and the rate of nitrification in the river should be looked at. . The issues mentioned earlier including, selenium, nutrients, and sediment should be examined. The only additional concern for this option would be a possible increase in the temperature of the ri ver. 6. Pueblo Reservoir Enlargement- · Inundation could damage viable Heron habitat and a recently improved state wildlife area near the reservoir. · Mitigation efforts in this area would be difficult due to the formation of the land and a lack of flat open space. · There could be water quality issues with this alternative including, metals and stratification of the reservoir. 7. Gravel Lakes Storage- · CDOW is more of a technical advisor for gravel permits than a regulating agency. . Gravel pits make "great fishing holes" according to the CDOW so public access should be considered. · If existing gravel pits are converted to storage areas there should be few problems in regard to the CDOW. However, finding a site to create a gravel storage lake could be more difficult. 8. Williams Creek Reservoir- . Eutrophication would be a concern due to the high amount of wastewater treatment plant effluent that would be entering the reservoir. . Inundation in this area could threaten the Prebbles Jumping Mouse. No surveys have been done in this area, if the alternative is chosen a survey would need to be conducted. 2
