That happened in our pasture at home. Except we were told that they would do all the fencing for free and provide a pump etc. but after that we were on our own to maintain it. It's built along a creek that has notoriously violent flooding at times too. This creek is quite often reduced to a dry bed, but there are a few days where a brave soul could take their life in their hands and boat it during a flood, so that makes it a navigable waterway. That also puts it under the jurisdiction of the Department of Fisheries and Oceans! Can you imagine? In the middle of the prairie we have the fish guys breathing down our necks.
We were offered no other money, but were told that if we didn't do the fencing now, we would be very likely legislated into doing it at our own cost a couple of years from now.
Now the far side of the creek has become overrun with burr plants and would be a nightmare to let cattle in to it. We're still not sure what we're going to do about that. Have they set up a scenario where the cattle stay out, but we're forced to use chemicals in there? If so it would probably be the first time in history that it's ever happened on that piece of land .. ever. So far other than not having to worry about drowning calves at springtime, there haven't been a lot of benefits to us that we can see yet. We always took good care of the creek in the past, never cutting out the brush or letting erosion happen, but then again what would we know about it? We've only lived beside it for the past 30 years. :?
