Warning: A sudden silt surge in the Mississippi delta almost took out our pump impeller

We were working a channel near Venice, Louisiana, when the suction head hit a pocket of pure, thick silt that the sonar didn't catch. The whole rig shuddered and the pressure gauge spiked past 80 psi in a second. I killed the pump flow and had the deckhand back us off slowly to clear the line before anything locked up solid. Anyone else had a close call with unexpected bottom material that the maps didn't show?

Read an article last year about a survey crew finding old riverbed timber buried under modern silt layers in that area. Like whole trees just sitting there, not on any chart. Makes you wonder what else is down there that the gear can't see until you're on top of it. That sudden pressure spike must have been a real heart-stopper. Glad you got clear without a full lock-up.

My buddy's dredge hit a clay shelf once, total nightmare.
