A simple trick to stop dredge lines from freezing over
Dredging in the cold months is a pain, especially when the discharge line freezes solid. We lost a whole day last winter because of it, lol. I started mixing in a bit of marine-grade antifreeze with the slurry, just a small amount. It lowers the freezing point enough to keep things moving. On my last job, we did this and had zero freeze-ups, even in sub-zero temps. Just make sure to check local regs so you don't mess with the environment. Hope this helps someone else out there!
