I’ve seen others off and on working on their R.R. that have water features that is an added up keep. Ponds are a messy item that I hate to get into. Every few years we have to drain our 38 foot pond and fix leaks and paint the bridges going over it. Also, gives us a chance to do Maintenance on the Swing Bridge that needs minor alignments and on the piers. The pond is around 3 foot deep and takes a few days to move the Koi’s to a temporary pond. Move all of the small bull frogs to the back reservoir for now.
