Hydrological Modeling

The Bureau of Reclamation is seeking hydrological modeling services to support the Klamath Project, specifically to assist with forecasting carry-over water storage in Upper Klamath Lake and stream inflow into the watershed system, including modeling hydrological changes following the removal of four hydroelectric dams on the Klamath River. The contractor will provide as-needed support to Reclamation hydrologists in implementing the Klamath Project Biological Assessment, with key tasks including developing models and analytical tools, calculating water flows, assisting with compliance assessments, and supporting daily hydrological operations. Personnel must have at least one year of experience evaluating and coding planning scenarios using Water Resources Integrated Modeling System (WRIMS) software, specifically related to the 2024 Biological Opinion. The evaluation will be conducted using comparative evaluation techniques based on total evaluated price including the base period and all option years. Quotes are due by September 5, 2025, at 10:00 AM Pacific Time, and vendors must be registered in the System for Award Management.

This procurement is designated as a 100% Small Business set-aside under NAICS code 541330 (Engineering Services). The contract structure includes a Firm-Fixed Price Purchase Order with a base period and four option years running from September 21, 2025, to September 20, 2030, providing a total potential performance period of five years. The contractor will develop spreadsheets, databases, and technical memoranda for tracking flow data, assist in developing new hydrologic analysis procedures, and support compliance with Endangered Species Act requirements. The work appears to be primarily analytical and modeling-focused rather than involving physical goods or large quantities of materials. While the specific award value is not disclosed in the available documents, the multi-year structure with option periods suggests a substantial ongoing commitment to hydrological support services for this critical water management project.
