About Rivistry
What Rivistry does
Rivistry combines public environmental data with carefully reviewed community observations. It is an educational and informational resource—not an official swimming-safety or emergency-alert service.
Find nearby rivers
Search by place and discover rivers and watersheds near your community rather than needing an exact river name.
Share observations
Contribute photos of wildlife, algae, erosion, litter, or changing conditions. AI offers a suggestion and submissions are reviewed before publication.
What the numbers reveal

connected system.
No single number tells the whole story. Rivistry brings related measurements together so seasonal patterns and differences between locations are easier to see.
