onWater Fish has teamed up with American Rivers to launch an industry first conservation feature: the American Rivers’ list of America’s Most Endangered Rivers® Map Layer.

onWater Fish, Trout Unlimited, USGS, and Conservation X Labs (previously WildMe) are officially launching TroutSpotter, a groundbreaking program that uses artificial intelligence to transform how anglers contribute to fisheries science and conservation.

onWater Fish and Project Big Wood have launched a mobile EcoWatch integration, to easily submit real-time Big Wood River ecological observations.

Discover onWater’s new California Trout Project Locator map layer—now live in the onWater app—to explore 60+ CalTrout conservation projects and connect with river restoration efforts across California.

onWater and Science on the Fly have launched an exclusive in-app Conservation Observation Tool to help volunteer anglers log real-time environmental data and support watershed restoration through tech-enabled community science.

‍New partnership enables anglers to explore exclusive fishing opportunities on private lands through the onWater app, supporting stewardship, rural communities, and sustainable land management.
