Thanks Sunil:

I have time and can wait for responses.

The past eight days, my wife and I built our dam. We ran into some problems.

When we closed the dam and the water rose, we had water running out of the left bank below the dam.

I had to dig into the bank and find the under ground channels. We found three channels and blocked them.

This seemed to solve the problem but I guess time will tell if the fix was permanent.

Now I want to build some lower dams. The idea is to have a series of pools along the creek and enough water in the rapids to allow fish to travel up and down the rapids.

I do not want the dams to be too high to prevent fish from jumping over the dams but I want them to be high enough to create pools along the creek.

I guess, to some extent, this is guess work.

Any suggestions will be appreciated.

Since this is an English site, I will refrain from using Spanish.
