From the Loveland Reporter-Herald (Jessica Benes):
Volunteers will clean up areas of the Big Thompson River, Dry Creek, Big Barnes Ditch and many more ditches…
Last year, 381 volunteers removed about 93 cubic yards of trash and debris. The stormwater division counts on about 400 volunteers and hopes to reach that number this week, which is when a lot of volunteers sign up.
As part of the stormwater permit through the Colorado Department of Public Health and Environment, the division creates a number of programs like the waterway cleanup to provide for public participation and education.
