Why Not Syphon The Reservoir?
The high-power pumps can empty the reservoir in four months and consume large amounts of energy. A hundred pipes could empty it quicker and cost little.
It occurred to me that a spillway is unlikely to be expected to drain a whole reservoir, just the excess. Still has to go somewhere without making a village into marshland. But good luck to them if they find a way. Having stated that, the clay/soil foundation seems fine. Unsure much draining is useful.
