new here, hello everyone. looking for insider knowledge. have gotten 8 inches of rain in two days. my pond at downstream has a pasture with 5 1500 pound steers. i have my pond overexaggerated brimmed alongside of and upstream of this drainage ditch/stream... well we got so much rain so fast, that this stream actually coming over the pasture breached the lower downstream side brim from overflow... it is a grass covered 3 acre pasture and a .60 acre pond 12 foot deep... the kids want to go swimming, how long should we wait? or have it tested for bacteria? thanks!
