Prosser Creek Dam Basin Cleanup

The Department of the Interior Bureau of Reclamation intends to solicit a firm-fixed-price construction contract for cleanup of the Prosser Creek Dam spillway stilling basin in Truckee, California, with responses to the Sources Sought notice due May 20, 2026. No set-aside is used; however, the notice targets small business concerns, including 8(a) small businesses, HUBZone small businesses, Indian small business economic enterprises, service-disabled veteran-owned small businesses, and women-owned small businesses.

Work is performed at Prosser Creek Dam in Nevada County, California. The contract period of performance spans 364 days from Notice to Proceed. Contractor must remove all materials from the spillway stilling basin including fine sediments (approximately 55 cubic yards), gravels, cobbles, and boulders (10 cubic yards), chain link fence materials, and large woody debris; remove material from two 6-inch diameter chute block drains to the greatest extent possible; and perform comprehensive inspection of the concrete floor and all spillway stilling basin features, documenting concrete deterioration with photographs and measurements.

The estimated project cost is $250,000 to $500,000. The contractor must provide 100% performance and payment bonds. A Government Inspector is required on-site at all times. Work must comply with NEPA requirements, Reclamation Directives and Standards, Reclamation Safety and Health Standards, and OSHA standards.

Prospective contractors must be registered in SAM prior to award and respond to marianna_mezentseva@ios.doi.gov by 5 p.m. PDT on May 20, 2026, with business information, statement of intent as prime contractor, evidence of relevant experience from the past five years (limited to three projects), equipment and personnel resources, and bonding capacity documentation. NAICS code 237990 applies with a small business size standard of $37 million.
