Prime42

Prime42.ai is a water-information platform focused on the Great Salt Lake watershed. It brings together public data from trusted sources, including USGS, NOAA, the Utah Division of Water Rights, HydroServer/USU, and Planet Labs, to help people follow water through rivers, reaches, and the lake. Its watershed map presents station locations and latest readings, while tools support tracing river flows, exploring reach water balances, and understanding water rights, laws, rules, and agreements.

Prime42 distinguishes measured or reported values from estimates, pending information, and results requiring review. Each answer identifies its sources, observation times, units, methods, evidence status, and, where publicly available, a replayable run record. The platform is designed to make agency records, research, policies, and legal information easier to find and understand for regulators, river commissioners, scientists, policymakers, researchers, and the public. Prime42 explains information without changing source records or replacing official state results. Users can create a free account to explore the watershed and access the sources behind individual results.
