# //RATING REMARKS="Stage discharge rating 001 was developed in Aquarius using discharge measurements 1-4, 6 and 7. The GZF was surveyed at ~5.00 ft with the rating GZF set at 5.21 ft to force a best fit to low flow MMT 7. It is possible the surveyed GZF is not the actual GZF in the cobble/boulder control. Three rating descriptor points were used with an offset of 4.8 to best fit the measurement data.  \\nThe rating error stats for the measurements used in rating development is 2.8% indicating a good rating fit. There was one outlier MMT 5 that plotted 12.8% from the rating and was not considered in the rating development. \\nA cross-sectional survey made Nov. 14, 2024 indicated the flow will overbank on the right edge of water at about 8.88 ft, well above where the rating extension out to 6.80 ft ends so no break point is necessary for this rating which was extended two times the highest measured discharge. \\n\\nRating control is a cobble/boulder riffle. More info on control in SD Rating Ops. \\n"

Large clumps of moss directly upstream of the control and some continued bank sloughing on the LEW above control. Discharge measurement upstream at 06137572 of 4.6 cfs confirms measured discharge. No diversions were noted upstream of the gage at Brown's. Assume shift is driven by aquatics and occurred over time as WT increased. "
