Is this campground monitored by the Northwood sheriff's department or Iowa Dept of Natural Resources? While driving through the park recently, there was a strong chemical odor noted during the drive through the park. There was one camper on site, and one vehicle parked, but it didn't really look like anyone was actually camping; no lawn chairs or anything that looked like "camping". The chemical odor was pungent through that area but it was hard to tell where it was coming from, since there is a fence that divides Silver Lake park from Sorbo campground right next door. Sorbo campground had several campers there, so for anyone not being able to smell it, would seem very odd. Never been around a meth lab but that was the first thing that came to mind.
