Refuge Project Size and Lands

The approved refuge boundary for Stone Lakes NWR — the area within which the FWS is authorized (depending on willing landowners) to acquire, protect, and manage land — is 17,640 acres. Within the approved boundary, the FWS owns or manages 6,206 acres. Another 5,000 acres are already owned by Sacramento County and several state agencies.

According to its FEIS, the refuge works only with willing landowners and is required by federal law to pay fair market value when acquiring an interest in the property. Thanks to these willing landowners and a number of cooperating agencies, the 6,206 acres under FWS management at Stone Lakes NWR include:

• 2,933 acres under cooperative agreements;
• 1,740 acres in fee title ownership; and
• 1,533 acres under easement.
