Established in 1994, Chattahoochee Riverkeeper (CRK) is a non-governmental and community science organization based out of Atlanta, GA that is dedicated to the protection, preservation, and stewardship of the Chattahoochee River and its watershed. Over the last two and a half decades, the work of CRK, the communities in which they work, and the City of Atlanta have and continue to create a cleaner Chattahoochee River that attracts more recreation, wildlife, and economic development.
The California Irrigation Management Information System (CIMIS) provides raw weather data, as well as information on evaporation rates and crop water usage, to inform irrigation decisions. A series of surveys demonstrated CIMIS was used to save water and increase crop productivity. The benefit-to-cost ratio of CIMIS to irrigation users was between $56 and $76 for every $1 spent.
