Local, state and federal agencies are collaborating to release about 800 million gallons of water from Twin Lakes, near the headwaters of the Arkansas River, into the river, according to a joint statement. The goal is to protect river health, recreation and fisheries from the effects of high temperatures and low flows. … [T]he additional water will help moderate water temperatures and reduce stress on fish during peak summer months of the drought. … The Southeastern Colorado Water Conservancy District approved the cooperative plan to use up to 2,500 acre-feet — which is about 814 million gallons — of water from an existing transbasin diversion that moves water from the Colorado River into the Arkansas River, called the Fryingpan-Arkansas Project.
