It would it you didn't have to worry about floating debris, especially logs with big branches sticking up. That's what catches in the fence and sheet metal and really tears things up, because the first one catches the ones behind it until eventually it just gets to be too much weight and blockage and it bursts by tearing the whole thing down.
The hanging panel method works, even though the cows could just walk through it if they tried, it just fakes them out that it is a wall, that's the easiest and most common method you see around here, except for floods, and this has been highly unusual floods. But if it continues, like an el nino weather pattern trend, I will have to rebuild it quite differently. Most likely an upper cable then a drop cable on pulleys attached to the upper cable with a stout winch, and just be vigilant on going down and raising it before predicted flood level rains and hoping for the best then. I'd MUCH rather do that than rebuild this thing all the time.
Ya, a geek-out automatic water level sensor and electric winch thing would be spiffy...who knows, might be possible with cheap hardware, maybe look into it. Run it off some battery up in the trees here someplace with a solar panel charger, maybe a modded electric fence rig. 12 volt winches are common, it's the sensor and relay action and start and stop solenoids and so forth I would have to look into to make it automatic. For now, if I had to do it by hand, no biggee, we do that with both sides of the greenhouse all the time now, similar cable and pulleys and hand winch arrangement. Those things I can get, but they are too light duty for heavy steel panels and heavy cable, they run just 1/8th inch (guessing, real thin) cables and light weight plastic walls. I'd want double that at least.
I ain't complaining much though! This over droughts any day! It's just a lot of extra off the wall and unexpected work. Heck, the county guys like I was mentioning are out now in the total dark clearing ditches, they got a dump truck and a backhoe going right up the street from us right now, I can still hear it. We being down in the creek valley are probably a higher priority for cleanup than the higher elevations around here, and most likely they realize do it now rather than wait for the next few days of rain.
