Update river basin model (RBM10)

The Department of the Interior US Geological Survey Office of Acquisitions and Grants seeks analytical services to update the River Basin Model 10 (RBM10) analysis of water temperature effects from Klamath River dam removal and publish findings, with quotations due August 3, 2026 at 8:00 AM Pacific Time.

This is a Firm Fixed Price RFQ with no small business set-aside. Place of performance is the vendor's facilities, with monthly progress meetings required with the technical liaison. The NAICS code is 541690, Other Scientific and Technical Consulting Services, with a size standard of $19.0 million.

The contractor must complete four primary objectives: compile post-dam removal water temperature data from 2024–2026 for model calibration and validation; run RBM10 scenarios comparing with-dam and post-dam thermal regimes; compare results to previous models and calculate biologically relevant temperature metrics for fall chinook salmon; and write and publish a peer-reviewed manuscript with supporting presentation. Deliverables include a peer-reviewed journal article and a regional science conference presentation, with objective completion deadlines ranging from October 31, 2026 through September 30, 2027. Period of performance runs August 10, 2026 through December 31, 2027.

Evaluation criteria emphasize technical capability, experience, and past performance over price. Vendors must demonstrate at least three years of relevant experience and capability in RBM10 model utilization. Quotations must be submitted electronically to Anthony Berry at Anthony_berry@ios.doi.gov and include a signed SF-18 form, UEI information, technical documentation, and firm fixed pricing.
