The stream starts on top of my land and flows down a steep hill. Nobody access it till it gets out of my land, so I'm clear of chemicals.
I think you are correct about the mud-pond thing. Mine is already cement anyway.
But a general question, how would I know whether a soil bottom will hold water or not? Is that a characteristic of the soil in particular location? Is there a way to figure that out?
okay2. i dont think soo, my mud pond is okay. i just dig and flows water in it. but the sides of a mud pond i think u should be wary about. i have carps and tilapia in my ponds and they sumtimes chew on the sides which could create a hole tht'll make water flow through, but if u cement it'll be okay. and a mud pond with rocks will be better as they will reduce the murkiness of water. a cemented pond is the same as an aquarium, u have to give special medicines and do regular water changes. but if there is always water supply flowing in and out then it's okay. eventhough a cemented bottom, their poop will not be disposed and can cloud the water, but this depends on where the water will flow out.
