RedactedNarrative: On April, 4 2012 I was on boating safety patrol near Hemenway Harbor on Lake Mead, Clark County, Nevada.  At 1046 hours NDOW Dispatch contacted me and advised of a boat accident outside the narrows above Callville Bay and the vessel was taking on water.  I responded to the call for service and arrived on scene at approximately 1056 hours, approximately 100 yards SW of Auxiliary Point.  A vessel was being towed by another vessel which had 4 occupants on board and one person remained on the vessel bailing water.  I took the four passengers from the assisting vessel and placed them on my patrol vessel.  I took over the tow  with subject remaining on board to bail water.  Vessel tow terminated at Callville Bay Marina at approximately 1149 hours.  The vessel was placed on a hydro hoist at the marina.  
  
  Two people both advised they were cruising at approximately 25mph when they struck a submerged rock near Auxiliary Point.  The two both provided a written statement.
  
  Damage consisted of fiberglass damage to the aft port underside hull, drive line, skeg and prop.  I photographed the damage and estimate the damage at approximately $3500.  
  
  I completed the initial accident investigation at a1245 hours and resumed patrol on Lake Mead.
