We depend on our streams for drinking water and other domestic uses, irrigation of crops, power generation, industrial use, aquatic life habitat, and recreational use. Water is a precious resource in the Boulder area, and how the volume of water flowing in our streams can vary a great deal from year to year, season to season, day to day, and even hour to hour.

Thank You! BASIN was a community project which benefitted from over 1000 hours of public volunteer time. BASIN was highlighted by the US EPA in a national case study in its 2001 handbook Delivering Timely Environmental Information to Your Community. Thank you to all volunteers, and especially to the late Jim Waterman, BASIN Project Coordinator!

BASIN was supported by the US EPA, the City of Boulder, the Keep it Clean Partnership, BCWI and BCN
