I had a few issues over the last couple weeks that I was finally able to address. Shortly after the last drain-fill, the waterfall leak came back. It was leaking in the same spot as it did last year. To fix the problem I spread out some of the rocks on the water fall, so the water is able to flow more down the center. So far it is looking like it should. When I finally turned off the pump while it was leaking it got down to about 8" in the pond. Being in the high 90's for the past couple weeks I filled it on 07-02 to about 14-15". (I started the fill during a lunch break and forgot about it until I was ready to go back to work).
Today I did a drain and fill and put in some chemicals. With the playing and working the pond started out at 13". I also put in some fertilizer pellets as well. The lilies are looking fairly well. One of them really took off. The other two seem to be a bit on the slower side. It might have been due to the low water and I know one of them the water line was just below the pot line. I am going to keep watching it closer and hopefully things will bounce back.
