Traveling by water go under the I-30 bridge heading north. Go left (West) after going under the bridge. Once getting to the west bank head north along the west bank.
You will find the culverts. They may be out of the water. Not sure. Haven't been there for many years.
I wasn't sure if it was the first or the second cove up there. I like the other one when the lake is up, personally. It has two ponds in the back next to the road culvert.
