Delta Waterway Cleanups
The Delta Conservancy helps organize and participates in cleanup events to educate and promote awareness of the importance of protecting and improving water quality in the Delta. The trash that flows into the Delta is a serious water pollution problem for both humans and wildlife. At the Delta Waterway Cleanups, volunteers actively participate in water stewardship practices by cleaning up trash and preventing it from reaching waterways and, ultimately, the ocean.
2025 Coastal Cleanup Day
Our 2025 fall cleanup event is scheduled to take place at Sherman Island on Saturday, September 20 from 9 a.m. to 12 p.m. as part of Coastal Cleanup Day. We will be co-hosting this cleanup with the Rio Vista Windsports Association.
See information about more Delta-area cleanups here.
Sherman Island Event Details
Help Rio Vista Windsports Association volunteers clean a 1.6-mile stretch of the Sacramento River along the north side of Sherman Island. Sign up in person the day of the event.
Report at 9 a.m. at “The Sign,” where leaders will provide an orientation, facilitate carpooling, and assign cleanup spots. Parking is difficult along the river, so volunteers are encouraged to carpool to their assigned spot. This site is not suitable for young children because of proximity to the road and rocky areas.
Directions
From south on West Sherman Island Road, take the left fork immediately southwest of the RV park and follow signs to park. There will not be a physical building upon your arrival, but you can use this address for your GPS: 4466 West Sherman Island Road, Rio Vista CA.
