i got a job which consists of building two retaining walls that are terraced. the guy wants a waterfall/pond coming out of the top wall and the pond in the middle between the two walls. it is not big, it is pretty small pond. but i have never built a pond. i have been researching and reading up on it and found all the materials i want to use. so, is there anyway that yall can show me some pics of some jobs if you have any from a waterfall coming out of a wall and a pond at the bottom. any help/advice would be great. thanks.
