Boulder Canyon Operations Office
About Us

The Boulder Canyon Operations Office (BCOO) consists of four specialized groups that support Reclamation's Lower Colorado Region programs:

  • River Operations Group - Manager: Bruce Williams

    The River Operations Group manages the delivery of Colorado River water. It works with other Reclamation offices, agencies, and interested organizations to develop long- and short-range plans to guide and control water operations at dams, reservoirs and powerplants on the lower Colorado River, and develops seasonal and annual operating plans. It also assures Lake Mead is operated in compliance with flood control regulations and collects and disseminates real-time data on lower Colorado River operations.

  • Water Conservation and Accounting Group - Manager: Paul Matuska

    The Water Conservation staff helps develop and implement agricultural and urban water conservation programs, and responds to emergency drought requests. The group also monitors Colorado River water use by entitlement holders to ensure it is being used beneficially, as required.

    The Water Accounting staff provides official records of diversions, return flows, and consumptive use of Colorado River water, as required by the Supreme Court Decree in Arizona v California (1964). Two primary reports are published on an annual basis: Article 5 Decree Accounting reports have been published since 1964 and the Lower Colorado River Accounting System reports are available from 1995.

  • Water Contracts & Repayment Team - Manager: Margot Selig

    The Water Contracts & Repayment Team manages the rights to use Colorado River water. This group develops and administers water delivery contracts and prepares economic studies and analyses to establish the ability of water users to repay the cost of Reclamation-constructed facilities. The Team also works with Colorado River water users to ensure compliance with all applicable Reclamation laws, including the Reclamation Reform Act; develops and proposes policy relating to water entitlements; and assists with special projects related to Lower Colorado Region and BCOO programs.

  • Operations Support Group - Manager: Seth Ostrowski

    The Operations Support Group provides field operational support for the Boulder Canyon Operations Office by maintaining the Region's Water Management Information System (WMIS) for the lower Colorado River, conducting stream gaging and field hydrological work, operating a river telemetry network, and providing scientific data acquisition for the river operations and water accounting functions of the office.

    In addition the group provides regional office level support for radio program oversight, joint Bureau of Reclamation-Western Area Power Administration telecommunications coordination efforts, underwater dive team engineering and environmental work, and watercraft fleet maintenance and operator training.
