Rivistry

Explore 47 rivers, understand official water data, and share observations with your community. Rivistry turns river measurements into clear context.

Rivistry helps you understand rivers through public monitoring data, place-based context, and community observations. Explore 47 river pages across Massachusetts, Connecticut, and New Hampshire. Start with the map, browse by state or watershed, or search for a specific river. See official measurements such as streamflow, including the monitoring station, unit, collection time, source, and historical context. Open charts and river dashboards to understand what each measurement means. Read Weekly River Updates for notable changes and patterns in official monitoring data. These summaries provide context and are not safety determinations. Share observations of plants, wildlife, water conditions, erosion, litter, and other changes in your local river community. You control location privacy, and we review every submission. Ask Rivistry questions about river science, measurements, and ecosystems using an AI guide designed to provide clear starting points and source-based context. Save favorite rivers and return to them across devices with an account. Rivistry is an educational monitoring and community-observation tool. It does not replace official health, safety, emergency, or environmental advisories. Always follow guidance from local authorities and official agencies.
