Come Prepared!

Use the checklist below so that you come prepared for creek conditions. Please be prepared to get a little muddy. Many of the clean-up sites may have poison oak.


  • Your own drinking water
  • A bucket or re-usable shopping bag to collect light trash (per person)
  • Comfortable, washable clothes
  • Long pants and long sleeves
  • Hat and Sunscreen
  • Gloves (work or gardening type)
  • Shoes that can get wet and muddy
  • Waterproof boots (optional)
  • Grabbing tool or rake (optional)



ALL CHILDREN MUST BE WITH A RESPONSIBLE ADULT as the debris, water, or slippery stream banks may be hazardous.

If you bring a child or group of children, your most important job is to supervise and keep them safe. Collecting trash is secondary for adults in charge of children.

Thank you for making it possible for them to have this experience!

Clean-up Site Locations:

Grizzly Island Trail Registration Link

Located in Suisun City, this trail runs for approximately 1 mile along the northern edge of Suisun Marsh where Laurel Creek flows into the marsh. It is a flat, paved, protected trail that is great for families with lots of beautiful views of the marsh and wildlife. The site is south of CA-12 and about 15 minutes east of I-80.

Directions and MAP   From I-80 travel east on CA-12. Take the Marina Blvd exit and turn south on Marina Blvd.  We will meet at the intersection of Marina Blvd and Driftwood Dr.


Lower Morrison Creek - Bufferlands Registration Link

This site, which is usually closed to the public, is great for families. It's complete with little challenges for younger volunteers and bigger challenges for adult volunteers. It is also just 10 miles south of downtown Sacramento.

Directions and MAP From I-5, take the Cosumnes River Blvd exit and travel east on Cosumnes River Blvd. Drive for approx. 1.7 miles and then turn right at sign onto a small dirt road. Follow the signs along the gravel road to the parking area. 10 mph speed limit.


Sherman Island Registration Link

Help the Rio Vista Windsurfing Association and the Sherman Island Kiteboarding Organization volunteers clean a 1.6 mile stretch of the bank of the Sacramento River along the north shore of Sherman Island. Meet at "The Sign" on West Sherman Island Rd. where site leaders will provide an orientation, facilitate carpooling and assign cleanup spots.

Maps to assigned spots will be provided here. Parking is difficult along the river, so volunteers are encouraged to carpool to their assigned spot. While it may be nice, it may also be very windy. Dress in layers and prepare for the winds.

CAUTION: Sturdy shoes and gloves are a must here because of unstable footing and glass on rocky banks. Parts of the river are accessed from the narrow road shoulder. Not suitable for young children.

DIRECTIONS: SEE MAP Meet at "The Sign" just south of Rio Viento RV Park on West Sherman Island Road. Take left fork immediately s/w of RV park.


Brannan Island Registration Link Site Closed

Threemile Slough runs along the eastern side of the Brannan Island State Recreation Area and then turns west to join the Sacramento River. This stretch of slough is in a beautiful part of the Delta and has lots of great wildlife viewing opportunities. It also has a lot of trash. The cleanup site is along the steep and rocky edge of the slough. Due to the difficult terrain, volunteers must be 12 years of age or older.

CAUTION: Due to the difficult terrain, sturdy shoes, pants and gloves are strongly recommended.

Directions and Map  The park entrance is on CA-160 just north of Threemile Slough Bridge and approximately 3.5 miles south of the Rio Vista Bridge. After entering the park, follow signs to the boat launch. We will meet in the boat launch parking lot.
