The Lindo Channel Recharge Feasibility Study will evaluate the potential to repurpose existing flood control infrastructure in Chico to divert excess flow from Big Chico Creek into Lindo Channel for groundwater recharge. Historically, this diversion has been used solely for flood control; however, this study aims to explore an additional purpose. 

Following an assessment to determine the minimum flow needed in Big Chico Creek to meet community needs (including health, safety, environmental, and recreational requirements), any excess flow above this threshold could be redirected into the Lindo Channel. The diverted water would then be allowed to percolate into the underlying groundwater system, recharging the aquifer. 

As part of the study, monitoring wells will be installed to measure changes in groundwater levels during and after stormwater recharge events, with a focus on areas near the Lindo Channel. 

The study’s overarching goal is to evaluate the feasibility of enhancing groundwater recharge in a subbasin area that has experienced declining groundwater levels. 

Key Project Tasks: 

• Determine flow thresholds for diversion based on water rights, habitat requirements, and downstream beneficial uses. 

• Calculate the expected recharge yield to assess the project's potential impact. 

• Evaluate infrastructure and stream improvement needs related to the current diversion system and channel capacity. 

• Identify environmental permitting requirements to ensure compliance with regulations. 

• Conduct percolation rate testing to gauge the channel's recharge ability. 

• Install a monitoring network including shallow monitoring wells and stream gauges to track water levels and flows. 

• Create a Preliminary Conceptual Design: Develop an initial project implementation plan to outline key steps for execution and management.

Project Outcomes 

• Feasibility of Surface Water Recharge: The study aims to determine the feasibility of using the Lindo Channel for surface water recharge. This includes evaluating water diversion thresholds, assessing the potential recharge yield, and identifying infrastructure or stream improvements that may be required. 
• Pilot Project Design: A pilot project will be designed to ensure that water can be diverted and absorbed effectively. This involves testing percolation rates and developing a project implementation plan. 
• Environmental and Regulatory Assessments: The study includes assessments of environmental impacts and regulatory permitting needs to ensure the project complies with state and federal laws. 
• Monitoring and Data Collection: The project will install monitoring equipment, such as wells and stream gauges, to track water absorption rates and project impacts. This will provide valuable data for future groundwater management efforts. 
• Stakeholder and Public Engagement: The study emphasizes public outreach, with meetings and consultations with local residents, government agencies, and other stakeholders to gather input and inform the community about the project.

Key Accomplishments 

• Stakeholder Engagement 
  • On October 23, 2024, the Vina Stakeholder Advisory Committee (SHAC) received an update on the Lindo Channel Recharge Feasibility Study. 
  • During the meeting, both the SHAC and the public provided feedback, requesting more detailed information on how the monitoring locations were selected. 
• Public Engagement 
  • The first public engagement meeting was held on November 13, 2024. 
  • The consultant team shared their research findings to date and received valuable questions and comments from attendees.
