At 0 feet, you will end up with silt being sucked though or accumulating/clogging. Also, the intakes are likely below the stated level, but you need X number of feet above that for water pressure to turn the turbines. Either way, I'm not sure that a retrofit is a feasible option.

A big filter at the intake?

Filters have to be cleaned, a process that is both expensive and dangerous at the bottom of a reservoir that high. Which is why the better solution is to put the intakes up a bit and allow the bottom of the reservoir to serve as a settlement pool.

That still doesn't solve the pressure part of the problem, and likely makes it even worse.
