Historical2020 USGS model-assigned cooling-system categories within the958 reviewed plant-year rows. Counts are model rows,not separate cooling systems or complete state facility counts. Complex means more than one cooling system type;do not distribute Complex rows among other categories. Once-through fresh and saline are literal source categories;do not classify all other categories as freshwater. Withdrawal sums are modeled annual-mean million gallons/day,not consumption,discharge,permits or available supply. A category with no selected rows has a calculated count and sum of zero within this dataset,not evidence of no statewide physical use. All five mutually exclusive model categories partition these rows;saline consumption remains unmodeled and is not inferred from withdrawals.
