This spring vent is located just north of Highway 20. The vent emerges from beneath a submerged limestone ledge into a 40-foot diameter pool. The mouth of the 50-foot run is on the west side of the creek approximately 600 feet north of the Highway 20 bridge. Maximum depth measured in the mouth of the vent is 11.5 feet but the conduit extends further and downward. There is a gentle surface boil. The pool is surrounded by a concrete wall to stabilize the bank and steps lead down to the water. There is a restroom and picnic area adjacent to the spring pool. The vent is on Water Management District land and is used for recreation.
