On 8/3/13 at about 2230 hours I Dep. was dispatched by MCSO communications to the address of 11720 Thousand Trails Willis, Tx 7731, a resort and RV park on Lake Conroe, reference a boat crash.  I arrived on scene at about 2240 and met with two subjects at the resort boat ramp removing vessel 1 from the water onto a boat trailer.  They both stated that they were traveling back from the area near the east end of the San Jacinto river Authority Dam, and had hit what they believed to be a stump in the water.  Exact speed and direction of travel unknown.  They made contact with other family members at the resort, and the family members were helped by a passer by who helped them locate Vessel 1 and tow them a shore.  I took photographs of the vessel.  the damaged area was on the starboard hull, near the keel line about a 3x4 foot hole torn into the fiberglass.  Information was gathered from the operator and passenger.  No further investigation. End report.
