We did not design or build the pond pictured below, we were called in to fix the issues the homeowner had with the feature. Water shot off of the top waterfall instead of falling off of it. There was poor flow over the lower waterfalls, the falls were "spotty", the liner was exposed in several places, and it leaked. We were called in to see if we could address the issues without a total rebuild, so that's exactly what we did!
Pictures below are of how it looked when we got there.
