RedactedNarrative: On Thursday July 11, 2019 V1 launched at Platte Creek Recreation area. V1 proceeded down river toward Cedar Creek. At the mouth of Cedar Creek, V1 encountered V2. V2 was positioned approximately 500' off shore. V2 had a 32" diameter pipe floated to the surface. V2 was tied off to the pipe with approximately 100' sticking out to the south. There was a large float bag under the end of the pipe that was approximately 8' tall above the surface of the water. There were 4 two foot tall red and white bullet style buoys placed every twenty feet along the pipe back to the location of V2. V1 passed approximately 50' to the south side of V2, between V2 and the float bag. V1 struck the pipe that was on the surface of the water and continued up and over the pipe where it eventually came to rest.
