RedactedNarrative: On 07/08/2017, at approximately 6:31pm, officers and KWPT Game Wardens were dispatched to the Tuttle Creek Spillway Marina in Pottawatomie County KS for a sinking vessel with individuals on board.  After speaking with the individuals, the operator of Vessel 1 (V1) stated he had V1 beached V1 on a sandy shorline along Tuttle Creek Reservoir so that occupants could swim and such.  All occupants got back onto V1 when finished and V1 started to makes its way back towards the Tuttle Creek Marina.  
  
  While in route, occupants of V1 started to hear the engine making some unusual noises and the engine eventually just shut off.  Occupants looked back and then realized that the back of the boat was almost to the water line.  Occupants immediately started to bail water and signal for help.  Another vessel in the area was able to come and assist and the 2 children from V1 were placed on to the helping vessel while the adults tried to bail water out of the boat.  An operator of a jet ski made his way over and was able to hook up to V1.  The jet ski tried towing V1 to the marina but was unsuccessful in its efforts and the boat took on too much water and sank in approximately 6 ft of water approximately 20 feet from the shoreline.  The bow portion of the vessel remained out of the water with the stern resting on the bottom of the lake.  Occupants were able to come aboard the KDWPT vessel and all belongings floating in the water we able to be retrieved.  No occupants of V1 sustained any injuries in the event.  They were able to contact an individual who was on the lake that day who did recoveries of sunken vessels.  Owners of V1 stated they were able to remove the vessel later that same night.  
  
  Owners of V1 stated that after observation of V1 they noticed a patch job in the hull that appeared to have given out.  The hole appeared to be approximately the size of a full size basketball.  Occupants stated they never hit anything or had any idea how the patch could have been punctured.  Owners suggested that it may have just failed.  Owners stated they were going approximately 20mph when the hull failure occurred.
  
  Nothing further.
