# //RATING REMARKS="Developed new rating due to higher flows in Apr/May 2023, low flows from 2018-2019WY, 2022-2023WY, and was based on new GZF from the 2022wy at 0.75ft. The upper end used Qm 177-178 from the 2023WY, as well as high flow measurements from 2021-2022wy as well as histroical high flows Qm's from 2018WY and 2019WY. The low end used Qm 179-180 from the 2023wy as well as Qm's 168-169, 171, 173, and 174, which showed slight fill. Balance the low flow Qm's. The lower to middle portion of the rating has a slope of 2.135ft indicating section control and then the upper middle and upper portion of the rating had a slope of less than 2, indicating channel control.
