Better Data Means Better Decisions

Communities can drive the data-to-policy cycle. DataStream is designed to support this.

Data-to-policy cycle: monitoring groups, open data, interpretation and knowledge, policy and action, and back to monitoring groups.
Policy & Action
Knowledge can be translated into action to protect the health of watersheds on which we all depend.
Monitoring Groups
Communities are connected to their waters and best-placed to see changes as they happen.
Data-to-policy cycle: monitoring groups, open data, interpretation and knowledge, policy and action, and back to monitoring groups.
Open Data
DataStream provides a place to store, share, and compare water monitoring data across watersheds.
Interpretation & Knowledge
Open data advances scientific knowledge, supports collaboration, and fuels innovation.
