The objectives for the use of cooperative agriculture in the National Wildlife Refuge System (NWRS) are: production or modification of specific cover types or growing methods that meet the life history requirements of species for which we have established objectives (e.g., waterfowl production); production of foods for wildlife species for which we have established objectives; and/or maintenance, rehabilitation, or reestablishment of natural habitat. Cooperative agriculture is when a person or entity conducts agricultural practices on NWRS lands in support of the Service’s conservation and resource management objectives and there is substantial involvement between the Service and that person or entity. The NWRS uses cooperative agreements, known as Cooperative Agriculture Agreements (CAAs), as the legal instruments to formalize the agreement between the Service and the program participant. The cost-sharing of a person or entity in cooperative agricultural on NWRS lands can vary depending on the needs and objectives of the particular NWRS land. For example, the Service may provide the cooperator with the right to perform agricultural practices on NWRS land and a percentage of any resulting crop yield, as well as the ability to use Service water, equipment, and/or refuge staff. In exchange, the cooperator may provide the Service with labor, equipment, and materials; a percentage of any resulting crop yield; and/or maintenance, rehabilitation, or reestablishment of specific habitat conditions on NWRS lands. In addition to or instead of cost-sharing, the Service may accept bids for payment for the person or entity’s agriculture use (e.g. haying or grazing) on NWRS lands in compliance with the Refuge Revenue Sharing Act. This is a nonfinancial assistance program. No Federal funds are obligated or awarded to program participants. Because a CAA is not a financial assistance award, it is not subject to the regulations at 2 CFR 200 or policy in parts 515 and 516 of the Fish and Wildlife Service Manual.

Using appropriations to the Great Lakes Restoration Initiative (GLRI), the U.S. Fish and Wildlife Service (FWS) anticipates providing grants to support development and/or implementation of Great Lakes Tribal Aquatic Invasive Species Management Plans (Tribal AIS Plans). Therefore, a Tribal AIS Plan must be in place that supports the proposed work, or development of such a plan must be a part of the proposed work. All tribal grants will be awarded based on a competitive process for which only Great Lakes tribes or their designee are eligible.

The Butte Creek Sutter Bypass West Borrow Canal (WBC) Weir #1 is a dilapidated weir structure and is no longer able to be used as a weir for the purposes of diverting and delivering water for agricultural use and to the United States Fish and Wildlife Service (USFWS) Sutter National Wildlife Refuge (Sutter NWR). The USFWS seek the design and permitting required for the partial removal of the weir and construction of a rock ramp that will maintain water surface elevations adequate to provide reliable water diversion rates and flows sufficient for fish passage. A feasibility study and report for Weir 1 has already been completed; final design and permitting are the next logical step in addressing the conditions at the weir. The flows required for diversion and passage should be consistent with minimum flow agreement requirements (M&T Ranch Agreement Decree Diversion 50) as well as flows through the fish passage structure at the Giusti Weir, located approximately 3.75 mile upstream. The flows of Butte Creek are diverted past the natural outlet to the Sacramento River (known as the Butte Slough Outfall Gates and under most conditions are directed downstream through the Butte Slough. The Butte Slough is bifurcated at a point just upstream of the State Route 20 bridge crossing, identified as the East-West Diversion Weir. The East-West Diversion splits the flows of Butte Slough to approximately 60% to the East and 40% to the West side borrow canals. Butte Slough above the East-West Diversion Weir is capable of handling a flow of approximately 2,000 cfs within its natural banks (Jones & Stokes 2002).The mission of the USFWS is "working with others to conserve, protect, and enhance fish, wildlife, plants, and their habitats for the continuing benefit of the American people". Fish and Aquatic Conservation is integral program within the U.S. Fish and Wildlife Service and supports the mission by working with partners to achieve benefits for aquatic species and their habitats. This project helps meet FWS Fish and Aquatic Conservation goals of a program working together to deliver resilient habitats, healthy fish, connected people, and strong partnerships.
