McMurry ponds are a great area and it even has a boat launch. There are rarely people in it and it's also a pretty area. The dirt road that takes you to it is located off of North College.
Here is a google map showing the McMurry ponds. Hemlock street should take you to a parking lot after a short drive down a dirt road. You drive across some train tracks. Once you are in the parking lot shoulder your boat a short walk to the pond. The trail to the pond forks, take a right, about 300 feet down is the gravel boat launch.
