So the canal I live on has a slow current through it and silt has been accumulating for years. There is about 2 feet to the silt bottom and the rumor is, the canal is actually 8 feet deep which I believe because I can push a kayak paddle with almost no resistance into the ground until it disappears.
I can currently get my Malibu through as well as the Wakesetter on the end of the canal, but I'd be a little happier with 4+ feet. Has anyone ever removed silt with something like a trash pump? I've found the piranha mini dredge (http://www.piranhapump.com/mini_dredges.html
) which looks like it is a trash pump coupled with an "agitator" pump so you're not pumping dense packed sludge.
it's pretty pricey even used ones that I've found online so I was wondering if anyone has any experience before I make such an investment.
