Bayley Reservoir, also known as Baley Tank, is a federal-owned water structure located in Modoc, California, near the city of Likely. This reservoir on Crooks Canyon was completed in 1970 and serves multiple purposes including fire protection, stock watering, and as a small fish pond. With a dam height of 10 feet and a storage capacity of 93 acre-feet, Bayley Reservoir is regulated by the Department of Water Resources and is inspected regularly to ensure its safety and functionality.

Managed by the Forest Service, Bayley Reservoir has a low hazard potential and is classified as having a moderate risk level. The spillway type is uncontrolled, with a width of 40 feet, and the outlet gates are also uncontrolled. While the condition assessment is not rated, the last inspection took place in September 2010 with a frequency of every 10 years. Despite its remote location, Bayley Reservoir plays a crucial role in providing water resources for firefighting, livestock, and recreational activities in the area, making it a valuable asset for the community and the environment.
