How far?

[Krazo]

how far is the lake backed up into the river?  I was thinking of taking the family to the pomme river (maybe niangua) but not too familiar with the lake or access points.  Looks like good access of 120th and 150th, maybe off PP too.  Anyone familiar with these locations?  can you easily get a canoe/ yak  or better yet a small trailer trailer dumped in at these locations?   id like to find some moving water, didnt really want to put in on the lake.
