RedactedNarrative: At approximately 1625 hours on Saturday, March 03, 2018, Game Warden (GW) with Kansas Department of Wildlife, Parks and Tourism (KDWPT) contacted GW requesting assistance with a suspected drowning at Tuttle Creek Reservoir, located 6 miles north of Manhattan, KS on K-13. 
  
  GW1 responded to the Incident Command Post at approximately 1837 hours. There she learned a witness had observed a male kayaker go under the water and fail to return. The Manhattan Fire Department had launched a rescue boat and recovered a PFD and a shoe, but the victim and kayak were still missing. 
  
  At approximately 0750 hours on Sunday, March 04, 2018, the KDWPT and U.S. Army Corps of Engineers (USACE) each launched a boat from the Wildcat Marina. A Kansas Highway Patrol plane was also assisting. At approximately 0810 hours the USACE located the kayak, an 8-foot orange plastic Pontomac, just under the surface of the water along the eastern shore, south of Carnahan Cove and near the Living Water Ranch. The Riley County Police Department recovered the kayak and a tackle box with fishing gear. 
  
  The firefighter who had witnessed the victim go into the water stood at the spotting scope in the same location he had been the previous evening and directed boat operator KDWPT Lt to the last known location of the victim. Lt marked the GPS coordinates of the location and marked it with a weighted buoy. A second KDWPT boat joined the search at about this time. All three boats used sonar to search approximately 400 acres surrounding the marked location of the disappearance. The search was postponed at approximately 1600 hours due to strong winds and large waves compromising sonar effectiveness.
  
  The victim''s father, met with the officers on shore and thanked them for their efforts. He stated his son was a strong swimmer and may have removed his PFD to try to swim to shore.
  
  At approximately 0700 hours on Monday, March 05, 2018, KDWPT and USACE personal met at the Wildcat Marina and concluded the weather conditions would not support search efforts on the water. KDWPT officers conducted vehicle patrols of the south end of the lake until sundown.
  
  At approximately 0730 hours on Tuesday, March 06, 2018, KDWPT officers met near the Tuttle Creek dam and concluded it was again too hazardous to conduct a search by boat. An officer continue to patrol the shore by vehicle until sundown.
  
  GW reviewed reports from the Riley County Police Department. According to the report written by Officer, subject1 had been bird-watching with a high-powered spotting scope from his lakeshore home, at approximately 1430 hours when he happened to see a male individual in a white shirt and blue personal floatation device (PFD) fishing from an orange kayak on Tuttle Creek Reservoir. 
  
  Subject1 was concerned for the kayaker''s safety because it was windy and the water was rough, so he kept an eye on him for approximately the next half hour. Subject1 then stopped observing in order to get something to eat. When he returned to the spotting scope shortly before 1500 hours, Subject1 saw that the kayaker was now in the water trying to hold onto the kayak. Subject1 called 911 and reported the kayaker in distress. 
  
  Manhattan Fire Department (MFD) responded to the subject1’s residence while a MFD rescue boat was launched. He observed the victim through the spotting scope, but visibility was intermittent due to large waves obscuring view. he saw the victim manipulating the buckles on the front of his PFD, apparently trying to remove it. The next time he saw the victim he was no longer wearing the PFD, which was floating several yards away.  A wave rolled over the victim and he was not seen again.  Neither the victim nor the kayak were recovered.
  
  The victim was later recovered.  His cause of death was drowning.
