RedactedNarrative: Watercraft #1 was anchored and tied to other boats at the sand pit located on the river north of Lock and Dam #3. 
  
  A 36' Carver went by, going 12-14 MPH south on the river. It was throwing an approximately 4 ft wake. The wake caused another watercraft that was tied to WC #1 to hit the starboard railing on WC #1. Operator #1 took a personal watercraft and caught up with Watercraft #2. Operator #1 also noted six to seven other small boats in the area and that they were not responsible for the large wake.
  
  Operator #2 advised he was southbound on the river. He passed the sand pit going about 10 MPH. Operator #2 noticed other boaters in the area going by and none of them were signaling him to slow down. Also, nobody alerted him over the marine radio to slow down. He didn't think his boat was throwing any bigger wake than was usual. He was at Lock and Dam #3 when a man on a personal watercraft came up and told him he was throwing a big wake. The man on the PWC told him he was responsible for his wake and he was calling the cops.
  
  Operator #1 advised of witnesses, but at the time of this report, none had come forward.
