Part II
The same time. You can see two depth levels.
Ok, I think that a little explanation about that kind of spillway is needed. In most cases here they are made like concrete chimneys with one side open. Wooden planks are put there to regulate the water level. If you wish to lower it then take one plank out and otherwise. When water reaches level of top plank, it flows in the chimney and gets to the pipe. There is one disadvantage – top layer of water is full with oxygen and it’s better for fish.
This time it is a bit more advanced. There are 2 layers of wooden planks and water is taken away from the depth.
I made 2 fast sketches just in case.
October:
So, when everything was done, we put the planks and started waiting for rain. Another water source is a little brook from other pond but its water amount is dependent on rain too…
1st November, some pictures.
