Title: Chief of Planning & Watershed Resilience

Contact: (909) 387-9241

NWSA Involvement: Member



Greg Woodside is the Chief of Planning & Watershed Resilience for San Bernardino Valley. He is a Professional Geologist and Certified Hydrogeologist in the State of California with a Masters Degree in Hydrology from New Mexico Tech and a bachelor's Degree in Geology from the California State University Fullerton. 

Greg manages San Bernardino Valley’s efforts on Forecast Informed Reservoir Operations (FIRO) at Seven Oaks Dam, salt and nutrient management, and evaluation of impacts of emerging constituents in water quality.  He also works on collaborative teams for the San Bernardino Basin Optimization Study, the development of the District’s Climate Adaptation and Resilience Plan, and the development of a monitoring and adaptive management plan for groundwater recharge near areas of existing groundwater contamination.  When previously employed at the Orange County Water District, Greg co-chaired the Steering Committee for FIRO at Prado Dam on the Santa Ana River.



Organization Type: Regional Water & Resource Management Agency.

Water Supply: California State Water Project, Santa Ana River and its tributaries water, recycled water. 

Population Served: 700,000.

Water Users: Seven Oaks Dam, located near Highland CA, currently does not have storage space allocated for water supply with the authorized purpose of the dam being flood risk management. San Bernardino Valley Municipal Water District (San Bernardino Valley), the US Army Corps of Engineers (USACE), local flood control agencies, and other stakeholders are evaluating Forecast-Informed Reservoir Operations (FIRO) coupled with enhanced groundwater recharge downstream of the dam.

Total Storage Volume: Flood risk management storage volume is approximately 145,000 Acre Feet.

Key Issues/Challenges:

The key issue/challenge faced by our region is drought.  Since 1945, we have experienced two droughts lasting 20 years, or longer.  We are currently in the midst of a drought that began in 1998.  Our agency was formed to help our region overcome the effects of drought by obtaining a supplemental water supply which we initially accomplished through investment in the State Water Project (SWP).  We are committed to the long-term viability and sustainability of the SWP supply through our additional investment in both the proposed Delta Conveyance infrastructure project which will protect against the potential effects of sea level rise and earthquakes along with the proposed Sites Reservoir which will provide much-needed additional storage space to capture additional supply. 


In recognition of the changing climate and hydrologic cycles, over the last 10-15 years we have made significant investments in securing additional sources of supplemental supplies including capture of stormwater and development of treated wastewater for groundwater recharge. As a complement to our investment in the SWP, we are committed to building a diverse water portfolio and actively investing in the optimization of our local resources such as pursuing FIRO to facilitate recharge of the groundwater basin downstream of Seven Oaks Dam; by strategically managing releases from the Seven Oaks Dam we can enhance the groundwater recharge downstream thus saving wet-year water for future use during droughts. 


Challenges include environmental factors related to endangered species and complex overlap of jurisdictional authority. For example, multiple parties are involved in the FIRO process because the Seven Oaks Dam is a Section 7 dam, operated by three flood control districts and requires USACE  approval for any change to the Water Control Manual.
