Last weekend I was trying to reposition a rock on the front of my waterfall that shifted over the years. Big mistake - slow motion rockslide of many rocks into the pond! Crap . . .
I took off work today at 11:30, put on my bathing suit and old sneakers I use for wading and got into the pond. Water temp not too bad, plus it was hot today.
I positioned a 2x4 from the waterfall to the side of the pond so I would have something to hold onto since the rubber liner is as slick as wet ice. Got all of the rocks out of the pond, rebuilt the waterfall façade/top mostly while in the pond - came out really nice.
Changed the design so the façade was not just straight up-and-down, more sloping like a mountainside. I had a lot of rocks left over. Added some to the rock "necklace" around my pond, piled the rest of to the side.
Three-and-a half hours, but everything came out better than I thought it would.
