I absolutely love coming out to the lake for a solid 3 mile or so hike. The views are awesome and the paths are easy to follow. There are view points you can stop at and plenty of nature to admire. I like sitting at the boat dock looking for snakes :)
The bathrooms by the boat dock are actually pretty clean for park bathrooms. They even have hand sanitizer available. There is also a huge park map by the bathroom so you can check out other possible trails, learn about the animals you are seeing, and plan your next hike!
After you hike the lake take some time for people watching at the base of the damn.
I always avoid the lake walk if it has been raining the day before - seems like it takes the path awhile not to be overly muddy.
I really need to make it out here more often :)
