Dudley Landry, thanks for the advise, I will do contact a hydrologist before I cut the levee. In the mean time, I will research other options.
Esshup, thanks in advance for your suggestion and for another option. What size pipe would I need for a siphon with such a high volume of watershed?
How about this idea, since the levee is u shaped and facing the west which is going uphill, I cut a trench almost at the beginning of the levee on each side, bury the drain pipe, have one side of my pipe running down the inside levee, shoot elevation for proper full pool and set inside drain in like a medal frame to avoid floatation?
