Phil,
Looking at the photo you can see a water mark, just below the plant of the bank on the right, which is my June through December water level. January starts the hot drier season and I will lose 2 or 3 feet before rain starts in May.
When I did the rocks without cementing them I had a great deal of erosion. The rain washed the soil away and the rock slide down the bank. I have sandy clay which may have contributed to the problem.


1/4 & 3/4 acre ponds. A thousand miles from no where and there is no place I want to be...
