Trying to get bentonite to drop on top of a "possible" leak and plug it would be like dropping a bare hook into the water and expecting to hit a fish on the head with it. Chances are slim.
I respectfully disagree. The "sprinkle method" does work sometimes as it has worked for me to stop seepage in a small holding pond. However I would not mix it with water before applying. I would dump a bag or two at a time in a wheelburrow and shovel it in the waters edge of the dam. Or very carefully dump in with a frontloader. The bentonite will quickly get saturated with water and sink to the bottom. You should be able see where it settles once the water clears. Spread it about an inch thick if you try this.
No guarantees but it worked for me.
