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. 
  
  Boats at the dock were a bayliner capri 1750 ls with nebraska registration number 594 jxn operated by another operator & (ia2020 0037) a caravelle interceptor with minnesota registration mn 0883 hv operated by operator 1 . Operator 1 had his boat tied to the dock and requested to take his family home prior to getting his boat off the water. Ranger agreed as it would take some time with each vessel. Operator 1’s vessel was taking on water but his bilge pump was working. 
  
  Operator 1 arrived back at the north ramps and began taking his vessel off the water. As it came out and drained, it was clear the lower unit of the volvo motor was missing. I took pictures of the vessel once it was out of the water far enough to be viewed. Once the water drained from the vessel, operator 1 took it to the parking lot. I handed operator 1 the "vessel occurrence operator's report form" and i began filling out the "vessel occurance officer's report form." once completed, operator 1 left.
  
  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 struck the pipeline last out of the three boats. 
  The adults on this vessel did consume alcohol.
