R23AP00568

Award Purpose:
The project has extensive public benefits, as it leads to recovery of listed and nonlisted native fishes. The project will be tidally connected to Miner Slough and, indirectly, to the Sacramento River, allowing juvenile salmonids traveling from the Yolo Bypass additional rearing habitat.

The project will address factors limiting fish populations in the lower Sacramento River Basin, such as food web production. The project is designed to increase food web production and allow distribution of food web production to the greater Cache Slough complex.

Activities to be performed:
Objective 1: Perform restoration to Prospect Island by repairing existing levees, providing invasive plant species control, constructing an interior channel network, constructing interior topographic features, toe berm, intertidal bench, and overflow weir, performing planting and revegetation, and breaching the Miner Slough levee.

Objective 2: Deliver the project efficiently and effectively (i.e., within budget and on time) while minimizing impacts to natural and cultural resources. This will be accomplished by performing project and construction management, cultural resources awareness training, and biological monitoring.

Objective 3: Maintain consistency with the proposed action as described in the 2019 Biological Opinion and receive mitigation credit for the project under the 2020 Incidental Take Permit. Meeting this objective requires documentation of baseline conditions, long-term management and adaptive management planning, and compilation of legal and real estate-related documentation.

Projected deliverables or outcomes:
The overarching purpose of the project is to restore 1,600 acres of uncultivated land to tidal habitat. The project will be used to maintain consistency with the proposed action as described in the 2019 USFWS Biological Opinion for the CVP and SWP and to meet voluntary agreement objectives towards updating and implementing the Bay-Delta Water Quality Control Plan.

Intended beneficiaries:
Enhance primary and secondary productivity and food availability for Delta smelt and other native fishes within Prospect Island and surrounding Delta waterways. Increase the quantity and quality of salmonid rearing habitat within and in the areas surrounding Prospect Island. Increase the amount and quality of habitats to support other listed species, to the extent they can be supported by site conditions and natural processes. Provide other ecosystem benefits associated with increased Delta freshwater tidal marsh habitat, including water quality enhancement, recreation, and carbon sequestration.

To the greatest extent practical, promote habitat resiliency to changes in future Delta conditions, such as land use conversions, climate change, sea level rise, and invasive species.
