C&SD, there's a little more to the story.
First, he's not damming streams. He's collecting rainwater runoff and snow melt into three ponds on his property. Yes, he's preventing that runoff from eventually joining into streams, etc. But there's no stream running onto his property that he's blocking.
Second, he got the permits from the state to build the reservoirs. The state then allegedly arbitrarily yanked his permits. When he didn't open up the ponds, that's when he got dinged the first time. At which point he opened the ponds up.
Once his probation was served, he once again closed the ponds, believing that he was legally right still. And he's still fighting this in court. The law the state is using is pretty specific in that it doesn't include rainfall, snowmelt, or "diffused" water. Only streams, etc. But they are now trying to argue that it does apply to the water sources he's using to fill his ponds.
So it's a big mess, and he's still fighting it in court, filing an appeal on his current mess.
