The Lake Lanier Association and volunteers from the community will pick up trash along the lake’s shores in the group’s 27th annual Shore Sweep today.

A cellphone app for reporting litter, “TrashOut,” has helped the association determine the best way to distribute volunteers for the clean-up.

Shore Sweep, which will run from 8 a.m. to 1 p.m., averages 1,000 volunteers and 30 tons of trash collected per year.

This year’s 12 participating locations are Lanier Islands, Clarks Bridge, Longwood, Don Carter, Gwinnett and War Hill parks; Aqualand, Bald Ridge, Gainesville and Port Royale marinas; and Balus Creek and Big Creek boat ramps.

Volunteers who turn in at least one full bag of trash get a T-shirt.
