Washington County Conservation has officially kicked off the spring camping season. The water has been turned back on at Marr Park and is ready to host campers. Reminders for campers include that camping spots are based on a first-come-first-served basis, and each spot costs $20 a night to rent. The campground offers 41 sites, all with 50-amp electrical hook-ups and water spigots. If you have any questions, you can call the Conservation Center at 319-657-2400
