Reclamation Announces Planned Test Release from Lake Nighthorse
Reclamation's Four Corners Construction Office will conduct a test flow release on July 23, from Lake Nighthorse, to continue evaluating the performance of the improvements constructed in Basin Creek to facilitate downstream water flow.

The flow release test will continue for approximately one week depending on results, as part of the required testing and commissioning for the Animas-La Plata Project prior to the project's transition to operational status. Released flows will range from 15 to 150 cubic-feet-per-second with the total release of water from Lake Nighthorse not to exceed 500 acre-feet. All flows released from the reservoir will pass through fish nets that ensure no escapement of live fish or eggs to the Animas River that could potentially impact endangered fish in the San Juan River.

The Basin Creek improvements consist of a series of channel improvements and small check dams, or drop structures, and were constructed as part of the Animas-La Plata Project. The purpose of the improvements is to convey water released from Ridges Basin Dam down Basin Creek to the Animas River.
