This county park is on the shores of Flowing Lake, the middle of the Three Lakes (the other two being Panther Lake and Storm Lake). Flowing Lake Regional Park has a campground with 48 campsites and four cabins; a trail weaves its way around the campground, which WTA has worked to help maintain. Other amenities include a playground, picnic tables and a picnic shelter, boat launch, fishing dock and an amphitheater.
Parking passes are required for day-use visitors, which can be purchased at the entrance fee machine. Day-of and annual passes are available.
