seems like the preferred method was pouring it into the irrigation canals while no one was looking...... The EPA frowns on that, as a couple of them found out!
Well, back in the day, the flush from our milk barn (60-70 cows milked night and morning)went right into the creek in front of our dairy. That crick was full of muskrats and rats, frogs and birds. The rats and birds seemed to really like the grain that got washed down. We'd flush the parlor and the holding corral night and morning with a big, 2" hose with water under good pressure. Didn't seem to harm anything.
