Covers primarily Colorado RIver, Roaring Fork River, and Crystal River, with some minor drainages. Accuracy of these maps is poor, due to inaccurate section corner locations of original paper map series. Margin of error typically exceeded the width of 500-year flood plain boundaries, so these lines have been dropped.
