Join your neighbors in getting the pond ready for summer – we will rake weeds, collect debris, weed the beach, and clear out invasive or spiky plants. Wheelbarrows, canoes, tarps, rakes, shovels, clippers, etc. will be needed that day.
Refreshments will be provided by the Association. Come see your neighbors after the long winter!
