Volunteer Opportunities

Out in the field, they contribute their time to various tasks such as water quality sampling, invasive plant removal, river cleanups, and wildlife and event photography. Throughout the community, they help educate the public about river and watershed conservation and promote our events. At headquarters, they use their unique talents to support our office work.

Volunteer opportunities are available year-round and vary based on the current season and needs.

Water Quality Monitoring

OARS’ Water Quality Volunteers are community scientists who play a critical role in monitoring and improving the health of the Sudbury, Assabet, and Concord rivers and their tributaries. Volunteers help sustain OARS’ long-running water quality monitoring program and contribute to one of the region’s most important river data sets.

Volunteer sign-up and training information for the upcoming season will be available soon. No prior experience is required, all training is provided, and volunteers must be 18 years or older.

Water Chestnut Pulls

Invasive water chestnut is a fast-growing annual and, if left unattended, will easily cover an entire waterbody. YOU can prevent it from clogging our rivers—Become an Weed Warrior.

Adopt-A-Launch

Help maintain canoe and kayak put-ins and take-outs on the Sudbury, Assabet, and Concord rivers. Improve recreational resources and encourages all visitors to our watershed to reduce litter and pack out waste. 

Volunteer Photography

We are looking for fresh new photos of wildlife, scenery, and activities occurring on, by, and in the SuAsCo waterbodies! And, someone to help us document the events and activities we host throughout the year.
