I got to help with some of the maintenance of my friend Ben's Dyno. It used water out of The French Broad River, which sometimes presented a challenge. Usually something knocked the intake pickup in the river out of whack. One time, we caught some tree hugging kayaker trying to break the 2" steel pipe because it upset him "Seeing" it under the water! Most of the time we just had to pull the pickup to the top of the water and make sure the screen was clean and then ease it back down. Last year, Hurricane Helene put an end to all of that with the flood that put him out of business.
