This is a great park and play spot! You can do anything here including cart wheels, spitwheels, blunts, etc.
The water comes out of 3 tunnels and is divided in half by a concrete wall. You want to play on the river left side. The right side can be nasty -- great paddlers have swam out of it.
Try to keep a low profile -- I have been harassed by the cops. It is best to park way down stream and paddle up to the dam. This is not very hard if you keep to the bank where the flow is very slow.

Bernie's Hole, which lies about a mile downstream.
