Projects
The Authority is committed to effectively managing surface water and groundwater resources in a manner that sustains agricultural practices and enhances the local environment. The Authority has implemented numerous projects to meet this commitment. To learn more, scroll through the project summaries below or choose a specific project on the left. Each summary has a link to a website or a project document (in Adobe Acrobat PDF format) providing additional details.
Cosumnes and Mokelumne Rivers Floodplain Integrated Resources Management Plan
The Cosumnes and Mokelumne Rivers Floodplain Integrated Resources Management Plan (CMRIMP) is a multi-agency effort designed to develop a management strategy that facilitates effective enhancement of floodplain conditions and functions of the lower Cosumnes and Mokelumne rivers. The goals of this project are:
  • Develop an Integrated Resource Management Plan (Plan) to guide the implementation of prioritized management actions that will effectively enhance floodplain and riparian habitats, flood management, and groundwater recharge along the lower Cosumnes and Mokelumne Rivers.
  • Engage stakeholders in the Plan development.
  • Utilize the principles of adaptive management in Plan development and implementation.
The Plan will identify a management strategy that facilitates the effective enhancement of the Cosumnes and Mokelumne Rivers floodplain. This project is currently underway and expected to be completed in 2007.

2002 Groundwater Management Plan
In 2002, the Authority developed and adopted a Groundwater Management Plan (GMP) to ensure that local groundwater resources are sustained and protected. The GMP is the Authority's first step toward developing a formal and integrated approach to groundwater management. The primary objectives of the GMP are:
  • Development of a groundwater monitoring programs that collects regular and consistent data to assist the Authority in evaluating and managing the groundwater basin.
  • Development of groundwater supply management programs that replenish the groundwater basin, sustain the basin�s water supplies, mitigate groundwater overdraft, and sustain storage reserves for use in dry years.
  • Development of groundwater quality management programs that identify and evaluate threats to groundwater quality and prevent or mitigate contamination associated with those threats.

Cosumnes River Flow Augmentation Project Summary
The Cosumnes River Flow Augmentation Project (Project) supplements the flow of the Cosumnes River by releasing up to 5,000 acre-feet (af) of water into the Cosumnes River from the Folsom South Canal. The objectives of the project are to:
  • Improve upstream fall migration of salmon, and
  • Evaluate groundwater recharge from the Cosumnes River channel.

Flow Requirements for Salmon Passage on the Cosumnes River
The Cosumnes River Fish Passage Project is a joint effort between the Anadromaus Fish Restoration Program, The Fisheries Foundation of California, and the SSCAWA. It is a study of the streamflow and water supply needs for adult and juvenile salmon passage in the river. The objective of the study is to assess the water supply and water resources infrastructure on the Cosumnes River, and to compare them to the water needs for successful upstream and downstream migrations of chinook salmon. Where there are deficits, viable flow alternatives and/or infrastructure necessary to make up the deficit will be identified. The ultimate goal is to describe a water management program that can meet the current needs of agricultural and municipal uses, as well as those for salmon passage, and not adversely affect rivers and streams outside the Cosumnes River watershed.


South Sacramento County Basin Groundwater Management Plan
SSCAWA, the City of Galt, Rancho Murieta Community Services District, and The Nature Conservancy teamed up to develop a Groundwater Management Plan (GMP) that represents the South Basin of Sacramento County. This GMP addresses the growing pressure on existing groundwater resources and on the natural environments that are now or were historically dependent on groundwater. The GMP identifies the participant's goals and objectives for groundwater management; and develops an implementation plan for reaching those goals and objectives, and for monitoring the success of the GMP. Development of this GMP teired off the 2002 GMP and was completed in January of 2012.

Lower Cosumnes River Memorandum of Agreement
The Memorandum of Agreement (MOA) for the Management for Water and Environmental Resources Associated with the Lower Cosumnes River has been entered into by the Sacramento County Water Agency (SCWA), the SSCAWA, and The Nature Conservancy. The goal of the MOA is to restore and maintain key functions of the Cosumnes River corridor while furthering conjunctive use in the agricultural areas between the American and Cosumnes rivers and from the Cosumnes River to the southern boundary of the county (Dry Creek). The signatories of the MOA hope to ensure the viability of both the agricultural economic base and ecosystems associated with the Cosumnes River. Through the MOA, the signatories are committed to working together to enhance conjunctive use within the region to reduce groundwater pumping and improve flow conditions in the Cosumnes River.
