I didn't look at the video but I bet its that one woman in Salem. Oregon law says that you can't pump water from a well for a commercial garden over 1/2 acre. A lot of the farm parts of western Oregon has irrigation, including most of the Willamette valley where Salem is. Irrigation rights are specifically for commercial farming and are often quite generous. There's not been a change in Oregon's laws. They're not "shutting down" small farms. This was one person who didn't bother to find out the rules and is now complaining about it. She should have gotten land with irrigation rights, or applied for them for her land.
While they're not perfect I think Oregon's water laws are a lot more sensible than California's. Until recently in California, you could do whatever you want with your ground water. Sounds great right? No government interference! But what's happened is that big commercial outfits put in huge deep wells with giant pumps and suck the aquifer dry. The ground's subsided 20 feet or more in a lot of the central valley as the water table falls. Lots of small people's wells have run dry and they have to pay for a deeper one. Basically this only works for the rich and big corporations.
In both Oregon and California you can collect all the rain water you want without a permit. It's Colorado where that's illegal. That's because of the Colorado river agreement with the other states on the river, not because Colorado hates farmers. The water that falls on the (western part) of the state ends up in the river.
