I live in Brooklyn Center and fish that stretch from shore on a very regular basis.
Yeah, the stretch from the Camden boat landing at Washington and Lyndale all the way up to CRD is extremely difficult to navigate unless you know where the channel is. I was out one day with my dad on that stretch and we hit a rock with the prop. When I looked at the GPS display later that morning it showed a freakin ISLAND in the spot where we hit the rock!
Also be warned that the boat landing at 694 is extremely steep, very long, and has a curve right at the very end just where the boats enter the water… I fish from shore straight across from there a lot and have seen many a would-be boater having issues with that landing.
The river along there has a tendency to suddenly double in width and go 2′ deep all the way across. Great for fording, horrible for boats.
If you wanna go for it, go for it. I woulnd’t take my boat up there when there’s so much other river available to be fished. On the other hand, there are a ton of wing dams to be played on or around and it may be worth while.
Just FYI – I’ve never seen a boat upstream of the south end of CRD park, and you can’t get beyond the bend in the river just downstream from the dam because the entire width of the river is a very shallow rapids across there.
