On Saturday, Oct. 13, Girl Scouts in Spring Grove will celebrate a Girl Scout Centennial event by working together to improve the local watershed.

Taking place in all 49 counties of the Girl Scouts of Minnesota and Wisconsin River Valleys Council, the "Centennial Day of Service: 2012 Take Action Project" is designed to remove 20,000 pounds of phosphorus, prevent 10 million pounds of algae growth and save $6 million in clean-up costs through a one-day effort.

Seventeen Girl Scouts in Spring Grove will spend the day raking leaves at Trollskogen Park and distributing door hangers in neighborhoods to raise awareness.

Every year, thousands of Minnesota, Wisconsin and Iowa waterways are polluted with runoff and other contaminants.

River Valleys' Centennial Day of Service honors Girl Scouts' longstanding tradition of service and gives back to communities that have embraced Girl Scout troops for decades.

In Spring Grove, girls will gather at Trollskogen Park starting at 9 a.m. Feel free to join them anytime from 9-11 a.m.
