On sheet 2, in the "Geomorphic Change Detection Uncertainty" section, "The magnitude of the measured change is within the propagated uncertainty, except . . ." was revised to "The magnitude of the measured change exceeds the propagated uncertainty in all cases, except . . ." In addition, ". . . can be interpreted to also be net-depositional. In the case of . . ." was revised to ". . . can be interpreted as net-depositional. However, in the case of . . ."

On sheet 2, in the "Storage Capacity Uncertainty" section, "σz2022,datum" was changed to "σz2022,DATUM" in the following text: "When the values σz2022,datum = 0.015 m (~0.049 ft) and σz2022,DEM = 0.056 m (~0.18 ft) are substituted . . . " 

On sheet 2, in the "Potential Implications to Reservoir Life" section, ". . . is the total volume of sediment that reaches Randy Poynter Lake (units of L3), . ." was changed to ". . . represents the total volume of sediment (in units of volume, L3) that accumulates in the lake over time, . . ." In addition, ". . . and vtotal is approximated from the volumetric change results of this study." was revised to "The value of vtotal is estimated based on the measured volumetric change observed in this study."

On sheet 2, in the "Potential Implications to Reservoir Life" section, "vtot" was changed to "vtotal" in the following text: "Reservoir half-life was estimated for the following three SY scenarios derived from different values of vtot (eq. 9) to demonstrate . . . " In addition, "Scenario 1: SY = 79.92 m3/km2/yr" was revised to "Scenario 1: SY = 154.74 m3/km2/yr" and "Scenario 2: SY = 154.74 m3/km2/yr" was revised to "Scenario 2: SY = 79.92 m3/km2/yr". Lastly, a double subscript "s" was changed to a subscript "s" in the following text: "Scenario 1: vmeas = vdep and vunknown = vdelivered,"

On sheet 2, the figure 4 caption was revised from "Bathymetric change for area within Randy Poynter Lake analyzed for geomorphic change detection (ARP) by using data from repeat bathymetric surveys completed in 2012 (Lee, 2013) and 2022 (Bolton and Whaling, 2023)." to "Bathymetric change within the full study area extent of Randy Poynter Lake (ARP) used for geomorphic change detection, based on repeat bathymetric surveys from 2012 (Lee, 2013) and 2022 (Bolton and Whaling, 2023)."

On sheet 2, the first sentence of the figure 5 caption was revised from "Bathymetric change map of Big Haynes Creek subarea within Randy Poynter Lake (ABH) by using data from repeat bathymetric surveys completed in 2012 and 2022." to "Bathymetric change within the Big Haynes Creek subarea of Randy Poynter Lake (ABH) used for geomorphic change detection, based on repeat bathymetric surveys from 2012 (Lee, 2013) and 2022 (Bolton and Whaling, 2023)."

On sheet 2, in table 2, the value 30,981.26 was changed to 5,326.31 and the value 25.12 was changed to 4.32.
