Rosedale-Rio Bravo Water Accounting Platform

In 2014, California passed the Sustainable Groundwater Management Act (SGMA), requiring local agencies to balance groundwater supply and demand; Rosedale-Rio Bravo Water Storage District responded by developing an open-source, online groundwater accounting and trading platform to help the district and its landowners manage their available water supplies and comply with SGMA.

Oroville Spillways Emergency Response

In February 2017, in the wake of severe storms, the California Department of Water Resources’ (DWR) Oroville Dam Main Spillway and Emergency Spillway sustained serious damage, including concrete failure and severe erosion on and adjacent to the Main Spillway and erosion downstream of the Emergency Spillway. Soon after these damages were identified, DWR began a wide range of repairs that also included substantial repairs to roads, power lines, fencing, and other security features, as well as revegetation and recreation-focused work throughout the project site.
