Great Miami - a) Heritage Park (or Blue Rock Rd) to Obergiesing Soccer Complex (Formerly Dravo Park) (OH)
Swift flows through the rapids, bigger waves, and crispy eddy lines. Rec and novice boaters may have issues.
AKA: "Lisa's Lagoon". A very short trip down the river and you'll encounter a V shaped ledge. Go straight for the middle of the river to get the best ride through some decent holes/waves. There is a small wave/hole above the actual drop that can be surfed. It's a challenge to get in and sets you up to go over some rocks backwards, but it's still good fun.
The ledge offers some surfing at almost any level. The river is constantly changing this area, so just look for the best feature and go for it.
At low water (below 1000 cfs), there' a spot closer to river left (surfer's right) on the ledge that will side surf a creeker (it's pretty small, just grabby).
