The Colorado Watershed Assembly (CWA) supports collaborative efforts to protect and improve the conservation values of our state’s land, water, and other natural resources by providing the network to connect a diversity of interests with Colorado's watershed groups and other decision makers.

One CWA strategic goal aspires to provide tools and resources for organizational development, connecting watershed organizations to one another in support of collaborative problem-solving.

The CDSN project addresses the top priorities echoed throughout the collective watershed management, assessment, and monitoring community in Colorado including the Colorado Water Quality Control Division, local governments, private entities and non‐profit organizations.

CDSN is helping to enhance Colorado's watersheds and water quality by providing CDSN's data partners and Colorado's citizens with an accessible and affordable tool kit for data management, data analysis, and data sharing.

Use Colorado Data Sharing Network (CDSN) to submit your data.

  • CDSN is currently helping 70+ different data organizations manage, share, and analyze 3.9 million water quality results for over 11,000 monitoring locations in Colorado.

  • Sharing data saves time and resources for others who are monitoring in the same basin. Sharing hosting, research and development costs for innovative data management and analysis leverages more resources for monitoring and other priorities. 

  • CDSN has saved its data providers over $1 million through shared hosting of the data management system vs. what it would cost for them to pay for hosting and support individually.
