OAKLEY - Anyone interested in learning about healthy watersheds is invited to spend a few hours near Spring Creek from 9 to 11 a.m. June 24. Join experts from the Lower Sugar River Watershed Association, Green County Land and Water Conservation Department and the Wisconsin Department of Natural Resources and spend the morning exploring the Spring Creek watershed, one of 13 tributary basins in the Lower Sugar River Basin. Oakley Branch, a smaller tributary stream, as well as the main branch of Spring Creek, will be examined to see what fish and invertebrate populations they support and for the overall health of the two systems.
