I have a small creek that has water most of the year, although it's not as clear as the water is in Roundoak's creek. I used to use it for watering the cattle most of the time. After we run the county water line through the farm, I put the Richie waterers in. The cows still have access to most of the creek, but they seem to prefer the cleaner water out of the Richie's. Cows play heck on creek banks and crossings, and I don't really care for that.
