This data release is associated with the following Scientific Investigations Report: Root, J.C. and Jones, D.K., 2022, Elevation-area-capacity relationships of Lake Powell in 2018 and estimated loss of storage capacity since 1963: U.S. Geological Survey Scientific Investigations Report 2022-5017, 21 p., https://doi.org/10.3133/sir20225017. This dataset provides elevation-area-capacity relationships for Lake Powell derived from a topobathymetric digital elevation model (TBDEM) that was collected in 2017 and 2018. The TBDEM was modified (Jones and Root, 2021, available for download at https://doi.org/10.5066/P9H60YCF) from the originally published version (Poppenga and others, 2020, available for download at https://doi.org/10.5066/P9XX0J1Y) for the purposes of this study. This dataset contains comma delimited (CSV) files for: (1) calculated tables of elevation-area-capacity relationships for Lake Powell at 0.33-ft (0.1-m) intervals; (2) interpolated tables of elevation-area-capacity relationships for Lake Powell at 0.01-ft intervals; and (3) an error analysis table conducted at 0.01-ft elevation increments across three elevation bands: lower (3,160.00-3,161.00 ft above NAVD 88), middle (3,400.00-3,401.00 ft above NAVD 88), and upper (3,700.00-3,711.00 ft above NAVD 88).

Elevation-area-capacity relationships of Lake Powell in 2018 and estimated loss of storage capacity since 1963
Lake Powell is the second largest constructed water reservoir by storage capacity in the United States and represents a critical component in management of water resources in the Colorado River Basin. The reservoir provides hydroelectric power generation at Glen Canyon Dam, banks water storage for the Upper Colorado River Basin, stabilizes water commitments downstream, and buffers the Lower Colora - Connect
