The Friends of Lake Darling are hosting their annual park clean up day on Saturday at 9am. Park Manager Merill Lucas says the friends group has been hosting this event for a number of years and they average around 25 volunteer each year. Lucas says this is the perfect time of year for this event because litter that is hidden by snow or tall grass at other times is visible. Anyone interested in participating should meet at the Lake Darling State Park shop near the entrance at 9am on Saturday. For more information call 319-694-2323
