Hi Perkassa man, there is about 18" of silt in the lake, it has taken 60 years to get that thick, apart from the rocks, bins, barbed wire that shredded my waders & other crap that people dump in it. The only viable solution is to empty it completely & get rid of all the detritus. You got a bargain when you bought that boat, it is so aptly named, took a while for his hand to heal, hope you have fun with it.
