    dct:description "This data release contains model inputs used to estimate surface water greenhouse gas fluxes from two large arid reservoirs, Lake Powell and Lake Mead.  The release also contains empirical, spatially explicit water quality and greenhouse gas data from a single field survey conducted in Lake Powell in July of 2017.  Finally, this release contains surface area estimates of shallow (&lt; 15m) tributary regions of Lake Powell under different water level scenarios." ;
