In addition, the rating was drawn to output 0 below the rating. A metal weir acts as the control and contains all but the highest flows. Rating 24.1 is fairly straight and uses a break point at 5.95ft (offset 5.00), as the slopes change slightly as flows transition into channel control. The lower offset aligns well with current GZF data. Shifting is generally minimal, with some minor shifting due to fill and scour in the gage pool just upstream of the weir.
