The Inter-Basin Coordination Analysis and Modeling Project focuses on analyzing Groundwater Sustainability Plans (GSPs) from subbasins along the Northern Sacramento River and Feather River Corridors to support inter-basin coordination and establish a shared understanding of basin conditions at the boundaries. The project also involves integrated groundwater-surface water modeling, including refinements to the Butte Basin Groundwater Model.   

The Northern Sacramento River Corridor includes the Red Bluff, Los Molinos, Corning, Vina, Colusa, and Butte subbasins. The Feather River Corridor includes the Butte, Wyandotte Creek, Sutter and North Yuba subbasins. 

Consultant: Montgomery and Associates 
Total Project Budget: $467,000 

Key Project Tasks: 

• Joint Analysis and Evaluation of GSPs - Evaluate and compare the contents of GSPs along each corridor region with a focus on establishing a common understanding of basin conditions at boundaries.  

• Model Updates and Enhancements - Update input data and parameter values in the Butte Basin Groundwater Model (BBGM). Model time period will be extended through Water Year 2024.
