Buttes Reservoir will need road construction and some fishermen-use facilities similar to those for Maxwell Reservoir. Hooker Reservoir lies largely within a canyon. It, too, will require road construction together with car-parking and boat-launching items. Charleston Reservoir will need similar improvements to capitalize on the fishery benefits. Marble Canyon Reservoir and its tailwater, lying within the inner gorge of the Colorado River, will be virtually unusable by fishermen unless access roads are developed together with appropriate boat-launching facilities including modification of the power-plant elevator to the tailwater below the dam. Bridge Canyon Reservoir and tailwater, also in the main gorge of the Colorado River, will be relatively inaccessible unless a good road is built and maintained into the reservoir and an elevator provided to reach the tailwater. Docking and launching of boats as well as carparking also will be needed at this reservoir. Fishery Management Investigations The impact of impounding waters in the reservoirs of the Pacific Southwest Water Plan will create problems in fishery management. There is a need for Federal-state cooperation in developing information needed for managing the extensive new waters to be developed with Federal financing. Without studies to develop such information, the state fish and game departments concerned will not be able to manage the new waters properly. Such studies should be conducted over the first five years for each impoundment. They will assist materially in bringing about the expected benefits. Rough-fish Eradication Virtually all of the new waters will need stocking with fish. But before the fish planting is done, the rough fishes frequenting particular streams or sections thereof should be removed so that the newly stocked fish may be given an opportunity to get a fresh start in new waters without having to compete for food or be preyed upon. Some areas are identifiable at this time but others are not. Particular care will be utilized in undertaking this program to prevent damaging side effects. Full compliance with the Department's careful policies and standards will be scrupulously required. Game-bird Watering Devices Largely intended for quail and other upland birds, these devices catch precipitation and store it for use by such birds. Very successful in arid areas, even though storage capacities of individual units is usually limited to less than 1,000 gallons, these quail guzzlers, as they are often called, are designed to make water available by runways as the water evaporates. Evaporation itself is reduced since the devices are sheltered. 22Epson Perfection 4870 Photo, 400 dpi, 8 bit, 14,581,760 byte
