RedactedNarrative: I, conservation officer responded to multiple boat accidents on lake manawa on 09/26/2020 at approximately 1658 hours. 
  
  When i arrived at the north boat ramps of lake manawa, i met state park ranger who advised that three boats had hit the dredge pipeline and were taking on water. 
  
  Two of the boats were located at the north boat ramps and the third was stuck on the pipeline. Council bluffs fire department were also on scene and had assisted the two boats back to the dock as well as the occupants of the third vessel. I ensured that no one was seriously injured as i made contact with individuals from each boat. 
  
  Conservation officer was en route and went to the boat stranded on the pipeline in the lake. The boat stranded on the pipeline was a mastercraft x43 with iowa registration ia 5819 br operated by operator 1. Operator 1 was located at the north boat ramps at the time of my arrival. I printed off the "vessel occurrence operator's report form" and handed one to operator 1
  
  Officer requested that the owner of the vessel still on the lake, operator 1 go to the fish and game club with his trailer. Operator 1 informed me that his trailer was already at the fish and game club and that he had a vehicle to get there. 
  
  Later in the evening, i met with individuals who were on the dredge at the time of the occurrences. They said that they took pictures of the boats and i asked them to email those to me and handed them my business card. They emailed me the next morning and those pictures are attached with the case file. 
  
  
  Officers and i then went onto the lake and used gps to mark the buoys and sign demarking the dredge pipeline. I have put those onto a map that is also attached to this case. Furthermore, signs are located at the public ramps on lake manawa identifying the different markers on the water in relation to the dredging project. I have included pictures of this sign on at the north boat ramps with this case. All boats were traveling in an easterly direction when they struck the pipe. 
  
  Operator 1’s vessel struck the pipe first(ia2020 0035)  puncturing it and remaining on the pipe.
