OK ... yeah, I was gonna try and find it on my Navionics Chartviewer on my computer & see if it shows any contours, depth, etc. but it appears to be too small a body of water for Navionics to even chart. I did look at it on Google Maps, and did see the weed islands (or what looked like weed islands). When you are referring to the "dam" ... is that next to the Jr High School ?
