When we moved to Ohio in 1966 we used to go to Spring Valley to fish. Ceasar's Creek wasn't begun yet, it was still farmland as far as I know. Used to go to the shootng range & there was public hunting grounds at Spring Valley. The lake was about 15' deep and you could camp right there near the parking lot. The bike trail today was still an active railroad track. The little store had food and a swimming pool close by you could pay to swim in. There was a hand pump in the campground to get your water from. I seem to recall a shack of sorts on a peninsula that ran diagonal into the lake with boat or canoe rentals, maybe bait too. I think (not sure). The lake was drained around 1969(?) because I know I was 16 & driving then, or maybe just rode with someone. Here's some pictures I took back on 3-6-2000 which happens to be my birthday too. It was a nice warm day. The Little Miami River runs behind this West side of the lake. I think those old stumps were part of the peninsula.
