The Department of the Interior, specifically the Bureau of Reclamation's Upper Colorado Regional Office, intends to award a three-year service contract for Data Buoy Services focused on evaporation monitoring at Lake Nighthorse and Lemon Reservoir in Colorado. The contract will involve the design, installation, maintenance, and technology transfer of buoys that measure evaporation data, with the first year dedicated to system design and fabrication, followed by two years of ongoing support. This initiative is crucial for adopting proven technologies in collaboration with local stakeholders, ensuring continuity with previous configurations. Interested vendors must submit written notifications of interest by February 7, 2025, and registration in the SAM database is required to participate in this sole-source procurement, which is expected to be awarded around March 3, 2025. For inquiries, vendors can contact Ana Fife at afife@usbr.gov or call 801-524-3671.
