Since there are no decent complete charts of the Occoquan Reservoir out there, I've always found the Reservoir to be a little difficult to fish, except when the fish are shallow or hanging on the obvious points.

Has anyone had luck using down imaging or side imaging on the OR?  Ever find anything interesting?  Any pics you can post?  I'm thinking of getting the small Humminbird unit to help on the reservoir and even on Burke... pressure is pretty high at both of those lakes these days and any advantage helps...

I saw a screen shot of an old bridge that wasn't on any map that someone found in Smith Mountain Lake on one of the down imaging sites... anyone find anything interesting on the Occoquan? (smithmountainlake.com/news/lakerWeekly/wb/224347)

The GMCO map of the rez is pretty useful.  The contour map of Burke is also useful (publically available), but, my advice is to ignore that body of water until the fall/winter/spring when you are not sharing the water w/ 40 other boats (an exaggeration, but not by much) and untold shore anglers.

I've been out on the rez with side imaging twice in a friends boat.  The most useful thing to us on those days from the SI were images of standing trees (still standing after ~50 years of flooding!) with associated bait fish.
