Slough Creek: The map is far from done, but I figured it'd be interesting to do a test using CheckOMap

I haven't looked at the results in great detail, but it looks like most of the notes are about places where a contour line shape is too tight/small. For example, a contour that shows a steep ditch/gully area where the edges of the gully need to be a bit wider apart. That might not be as big an issue as the map is going to be 1:10000 and CheckOMap uses 1:15000.
