You need thousands of tons of large objects that will not wash easily. Dropping stones? May as well drop ping pong balls. The water pressure is enormous.

If these jerks want to stop erosion, ask the Pentagon if CA can have a few hundred 40 ton mothballed tanks. Sikorsky twin rotor choppers can drop them inthe giant hole.

Yep. They would be water tanks.

Sikorsky makes a twin rotor helo?

Even the Russians can’t pick a 40 ton tank with a helo.
