ROSWELL, Ga. (AP) — Volunteers are needed to help with Georgia's annual "Rivers Alive" cleanup program.

The 28th annual event is being held at Riverside Park in Roswell from 8:30 a.m. to 11 a.m. on Saturday, Sept. 22.

The Atlanta Journal-Constitution reports volunteers will pick up litter along local roads and in the river, remove privet — an invasive plant species — and mark neighborhood storm drains. Some groups will be tasked with guided canoe cleanups, heading out on the water near the Chattahoochee Nature Center.

Georgia has more than 70,100 miles (112(asterisk)815 kilometers) of rivers and streams and officials are asking civic and social groups to help maintain them.

For more information and to register, visit the city's website or contact Vicki Culbreth at 770-641-3742.

The registration deadline is Sept. 14.
