Fish Shelter

They tell me I need a shelter for the fish. I guess to hide from the Kingfisher? So being fiscally frugal (cheap), I used an old chimney block and stuffed it full of larch branches. I used the chimney block thinking it would hold the branches under water. Between the weight of the block and all the branches, I could only manage dragging it into the water. Once in the water however, it would only stay partially submerged. I had to find some rocks from the shoreline for additional weight.

Incidentally, the water was still sufficiently warm to swim on this 80 degree plus September 21 Friday.
