Adult Salmon and Steelhead Passage Module Development

The contract involves the development of a C++ software module designed to simulate the migration patterns, dam passage, and survival rates of adult salmon and steelhead as they navigate the Columbia River hydropower system. This module will incorporate models that reflect the behavioral patterns and mortality risks faced by these fish species throughout their journey. The work aims to support environmental and ecological studies by providing detailed simulations of fish movement and survival in a key river system affected by hydropower infrastructure. Issued by the Department of Commerce through NOAA, the contract is structured as a subcontract opportunity with a focus under the NAICS code 541620, indicating specialized scientific and technical consulting services. Located in Seattle, the place of performance, the contract was posted in May 2026, with responses due by early June 2026, highlighting a relatively short proposal window. While the solicitation does not specify set-aside provisions, it carries significance in contributing to fisheries management and conservation efforts by enhancing predictive modeling related to fish passage and survival in regulated river environments.
