USGS Water Use Program - Natalie Houston
1. Water-Use Program
Texas Alliance of Groundwater Districts (TAGD) Business Meeting
Natalie Houston, Rich Niswonger, Jaime Painter, Ayman Alzraiee, Jon Haynes, Melissa Harris, Cheryl Dieter, and Jeremy McDowell
June 6, 2023
3. 3
Drivers for the Program
• Section 9508 of the SECURE Water Act (Public Law 111-11)
• Maintenance of a comprehensive national water use
inventory to enhance the level of understanding to the
effects of spatial and temporal patterns of water use on
availability and sustainable use of water resources
• Integration of any dataset maintained by any other
Federal or State agency
• Focus on integration of any data related to water use,
water flow, or water quality to generate relevant
information relating to the impact of human activity on
water and ecological resources
• National Academy of Science, 2002 and 2018
• Enhance spatial and temporal data collection
• Increase focus on the relationships between human
activities and water
• Water accounting should include estimates of
consumptive verses non-consumptive water use
• Engage in collaborations to develop new data sources
and platforms
4. 4
Future of National Water-Use Reporting
• Transitioning to Nationally consistent physics-based and data driven models that can:
• Provide estimates and forecasts of withdrawals and consumption at finer spatial and temporal
scales.
• Evaluate the relationships between the amount of water withdrawn and consumed.
• Determine the drivers behind the use.
• Enhance the collection and completeness of water use information
• Many local and state agencies collect data at finer scales both spatially and temporally.
• Automate data input process
5. 5

monthly) for all major water-use categories.

Irrigation Water-Use Model
Evapotranspiration (OpenET-
SSEBop)
Irrigation Withdrawals (WUP)
Hydrologic Model (NHM)
We use these estimates
in our hydrologic
modeling to determine
amount of irrigation
needed by crops.
OpenET, a multiple agency
collaboration, provides the
computational resources
and algorithms to provide
evapotranspiration
estimates (irrigation
consumptive use)
Finally, we estimate
groundwater and surface-
water withdrawals by adding
conveyance and irrigation
system efficiencies.

Thermoelectric Water-Use Model
• Process Driven Physics-Based Model-
requires gross electrical generation and fuel heat but
the latency of the data from EIA is about 6 months
after use
• Data Driven Machine-Learning Model-
used to operationally predict electricity generation
and fuel heat for the Physics Based Model
Model Data
• Plant characteristics:
• Cooling type
• Fuel type (coal, natural gas)
• Boiler type
• Environmental data
• Water temperature (NHM)
• Atmospheric temperature
• Plant operations: *latency*
• Electrical generation
• Fuel Heat
• Reported Water Withdrawals and
consumption
