Don Edwards San Francisco Bay National Wildlife Refuge Hunting Permit
It is required that all hunters possess a Don Edwards San Francisco Bay National Wildlife Refuge: 2024-2025 Waterfowl Hunting Permit when hunting in the Alviso Ponds. It is recommended that hunters also carry this permit when hunting in the Ravenswood Unit and Mowry ponds. The sloughs and open bay are subject to California Waterfowl Regulations and a refuge permit is not necessary
Hunting Areas
Alviso Ponds AB1, A2E, AB2, A3N, and A3W
- Located in South San Francisco Bay between Stevens Creek and Guadalupe Slough (Map 2 AB1-A3W)
- Hunting allowed on Wednesdays, Saturdays, and Sundays only
- Hunting is allowed from existing blinds only (Maps 3 AB1, A2E, AB2)and(Map 4 A3W, A3N). A boat or raft is needed to access these blinds and a boat ramp is located at the check station.
- Access to AB1, A2E, and AB2 is by motor vehicles from the end of Crittenden Lane in Mountain View
- Access to A3W and A3N is from the end of Carl Road in Sunnyvale (Please read “Driving Directions” on our website)
- No hunting from the levees - levees are shared with public trails
- No shooting allowed towards the adjacent levee trail (open to the public year-round)
Alviso Ponds A5, A7, and A8
- Located in South San Francisco Bay between Guadalupe Slough and Alviso Slough (Map 5. A5, A7, A8)
- Hunting allowed on Wednesdays, Saturdays, and Sundays only
- Access to ponds is from the Gold Street gate in Alviso (Please read “Driving Directions” on our website)
- Hunting from the levees is allowed (walking or bicycling on levees is allowed). Hunters must maintain a minimum distance of 300 feet from adjacent hunters when hunting on the levees.
- Hunting from a boat is allowed – blinds are not available in these ponds
- Hunters must shoot over Ponds A5/7/8 so not to interfere with adjacent hunt areas (in sloughs and nearby ponds)
Motorized vehicles on levees are not allowed (motorized bikes, ATVs, etc.) beyond the parking area
Alviso Pond A6 and A19
- Located near the Mowry Slough Unit in South San Francisco Bay between Mowry Slough and Coyote Creek
- Hunting is allowed seven days a week
- Access is by boat only—boats must access from the bay and hunt from the boat inside the pond
- Shooting from levees is prohibited
- No land or tidal marsh access is allowed, except to retrieve downed birds (due to endangered species present)
Ravenswood Ponds R1 and R2
- Located on the west side of the Dumbarton Bridge (parking along frontage road is available)
- Hunting is allowed seven days a week
- Hunting is allowed from the existing levees (top of levee to the toe of the levee) and from a boat
- Access to ponds is by foot or bicycle from either of two trailheads off Highway 84 (Map 6. Ravenswood)
- Hunting is prohibited within 300 feet of Highway 84 and the PG&E Substation
Bair Island and Greco Island
- Located on the west side of the San Francisco Bay, north of Dumbarton Bridge (Map 7. Bair Greco)
- Hunting is allowed seven days a week
- Hunting is allowed by boat in tidal areas (including Redwood Creek, Smith, Steinberger, and Corkscrew Sloughs). Be sure to check tides at the Bair Island Aquatic Center.
- No land or tidal marsh access is allowed, except to retrieve downed birds (due to endangered species present)
Mowry Ponds M1, M2, M3, M4, M5, M6
Although the refuge owns the Mowry Ponds and hunting is allowed, Cargill manages these ponds for salt production.
Due to an agreement between Cargill and FWS, Cargill has salt making rights in perpetuity on these ponds and FWS cannot impose any management regimes that would interfere with these salt rights. Therefore, the Mowry Ponds will be CLOSED to hunting when Cargill's "Mallard" dredge is present or any other levee maintenance activities are taking place (visible dozers, excavators, dump trucks, or graders). Our priority is to ensure safety of hunters, Cargill staff and refuge staff. However, if the “Mallard” or any other levee maintenance activities are not present or taking place within the Mowry Ponds, they will be open to hunting according to the following regulations:
- The Mowry ponds are only accessible from the sloughs and the Bay by boat (no land access)
- Hunting is allowed seven days a week
- Hunting is only allowed from a boat inside the ponds - hunting from the levees is NOT allowed
- No hunting is allowed with 300 feet of the Mowry Pond levees
- As with all salt ponds, tampering with water control structures is not allowed, for example: no opening/closing screw gates, no tampering with pumps or pump stations, no tampering with wooden gates, no attempt shall be made to manipulate brine levels, no access to walkways, boardwalks, pump station platforms, or any other infrastructure, no construction of any duck blinds, decks, docks, boat launching facilities, anchoring posts, etc., no digging on or into any levees
- These regulations will be strictly enforced and Refuge privileges may be revoked by the Refuge Manager or Refuge Officers for any alleged or suspected violation of these regulations.
- Hunters should be aware that Cargill employees, refuge staff, and other Cargill or refuge representatives may access the ponds at any time for any reason.
Tidal Areas
Tidal areas include salt marshes, sloughs, mudflats, and open water of San Francisco Bay. Unless posted in the field and/or noted below, all tidal areas in the refuge are open seven days a week to hunting from a boat, and only up to the mean high water line.
The following tidal areas are CLOSED to hunting and should be posted as “closed” in the field:
- Newark Slough is closed to hunting and shooting from its source to the Hetch-Hetchy Aqueduct, a distance of 3 miles.
- Dumbarton Point Marsh to the Hetch-Hetchy Aqueduct (west side of Newark Slough) is closed to hunting and shooting.
- The headwaters of Mallard Slough, in the vicinity of the Environmental Education Center, are closed to hunting.
Bird Retrieval
As noted in the regulations on page 4, we encourage the use of retrieval dogs on the refuge. Ponds are generally shallow; however, we do not recommend walking on the pond bottoms. Pond bottoms consist of very fine bay mud and one may sink in the mud several inches or even feet. Hunters also may retrieve birds using boats/rafts and we have heard that rigging fishing poles also works well. Whatever the method, we want you to make every reasonable attempt to retrieve your birds. Walking in sensitive tidal marsh vegetation is also acceptable for retrieving birds.
Boat Access
Hunters using boats to hunt the refuge have had a limited number of access points for launching their boats. A boat ramp at Redwood City serves Bair Island, Greco Island and Ravenswood Slough, and is sometimes used by those hunting the east side of the Bay (both on and off refuge lands) and other areas further south (both on and off refuge lands), but this can be difficult when the weather is rough. Hunters use the Newark Slough boat ramp to access ponds and marshes on the east side of the Bay and some areas closer to the south end of the Bay. This boat ramp is only usable at high tides. Santa Clara County Parks has a boat ramp on Alviso Slough. Please check with the Santa Clara County Parks for rules and regulations.
Boat Registration
Any sail-powered vessel over eight feet in length and every motor-driven vessel (regardless of length) that is used or moored on California waterways (including private lakes/ponds) must be registered with the California Department of Motor Vehicles or documented by the U.S. Coast Guard. Specific requirements and the application form can be found online with the California DMV Both the U.S. Fish and Wildlife Service and the Santa Clara County Sheriff's Office will be enforcing this requirement. If storing or using your motor boat on refuge property, you must register your boat first. If a boat is propelled by oars or paddles, or if it is a non-motorized sailboat that is eight feet or less in length, it does not need to be registered with the California DMV. It is also important to be aware of all State and Federal boating laws and safety guidelines as approved by the U.S. Coast Guard and National Association of State Boating Law Administrators. More information can be found here.
Waterfowl Hunting Regulations
- The Refuge Waterfowl Hunting Permit is for authorized waterfowl hunting access in the Don Edwards San Francisco Bay National Wildlife Refuge only – all other unauthorized access or use is strictly prohibited.
