Water Operations Control Center

Water operations on the lower Colorado River are governed by laws and regulations that primarily address flood control and downstream water demands. Within these schedules, recreational, environmental and other factors are addressed when possible. On occasion, water schedules can be modified to meet special needs.

The Boulder Canyon Operations Office (BCOO) Water Operations Control Center in Boulder City, Nevada, performs water scheduling and river operations functions for the lower Colorado River from Lake Mead (Hoover Dam) to Parker Dam.

Water Operations Control Center staff can be contacted with requests for special operations from Lake Mohave to Parker Dam, as well as considerations for operations of Lake Moovalya and Headgate Rock Dam. Special requests may include water schedule changes, lake elevation concerns, flows below dams during holiday weekends, reporting of problems with river flows, or planning for community special events. These requests should be submitted at least a month in advance to the BCOO Water Operations Control Center. These special requests will be addressed only if operational criteria permits.
