63-year-old Andrew Blair Howard, was convicted with tampering and vandalism by the Western District Court of Michigan
According to the U.S. Attorney's Office, Howard used a shovel and rocks to divert the Platte River on August 15th, 20-22.
Within a few days, the altered flow created a new river channel that grew to be approximately 200-feet wide.
The judge ruled that Howard -quote- "intended to and in fact did divert the flow of the Platte River."
The Park Service has not publicly announced plans to restore the channel, following the illegal diversion.
