On Highway 190 between the California towns of Springville and Porterville is the Success Dam and Lake scenic lookout. I stopped to visit once, but there wasn’t much to see. In the pretty big parking area were a couple of overflowing trash cans and port-a-potty I was not brave enough to visit. There’s a low stone wall separating the parking lot from the lake (which I suspect was much lower than usual, due to the California drought), and an information sign on the wall.
The day was hot and windy, and if the water in the lake helped cool the air, I didn’t notice. I only stayed long enough to take some photos of the lake and what I think were datura flowers growing on the land between the parking lot and the water.
(I took all of the photos in this post.)
