The Bureau of Reclamation is seeking information from vendors capable of providing an acoustic receiver/datalogger system for fish monitoring within the Central Valley Project (CVP). The government intends to acquire twelve units for remote, long-duration autonomous operation, requiring compatibility with existing Lotek acoustic telemetry systems. Minimum salient characteristics include a battery life of at least 200 days, a depth rating of 400 meters, and 8 GB removable microSD data storage. Responses are due by June 12, 2026, at 10 AM PDT, and must demonstrate the ability to meet all requirements. No budget amount or performance location is specified.
