Eric Averett is general manager of the Rosedale-Rio Bravo Water Storage District in Kern County, California, which is one of 21 regions required by the state to balance groundwater demand and supply within 20 years under the Sustainable Groundwater Management Act. Rosedale is home to approximately 27,500 acres of irrigated cropland and 7,500 acres of urban development. Groundwater demand there exceeds supply by approximately 5,000 acre-feet per year. To inform landowners about their water budgets, Rosedale partnered with EDF, Sitka Technology Group, WestWater Research and local landowners to co-develop a new online, open-source water accounting and trading platform. We asked Eric to answer a few questions about how the platform will help local landowners and how it can be expanded to other parts of the Central Valley.
