Water Data

Drought Declarations
Drought emergency declarations are issued by IDWR, are approved by the Idaho governor and apply only to the administrative processing of water right applications.

Geothermal Resources
What characteristics designate water as a geothermal resource in Idaho? Find information about the management and monitoring of geothermal resources and geothermal wells, and view interactive maps.

Ground Water Levels
IDWR's Hydrology Section analyzes data to determine regional ground water level trends, evaluating ground water availability for new water uses and identifying areas with declining ground water levels that may need administrative action.

Ground Water Quality
The Statewide Ground Water Quality Monitoring Program provides valuable information about Idaho's ground water quality to private citizens, consulting companies, and governmental entities.

• Environmental Data Management System
  A central computerized database designed to house selected Idaho environmental data.

Hydrologic Projects
The Idaho Water Resource Board and IDWR collaborate to conduct a comprehensive aquifer planning and management effort including performing technical studies, hydrologic monitoring, measurements, and basin plan development.

Water Measurement
Guidelines and procedures for collecting water measurement data and reporting the information to the IDWR have been developed in order to have an orderly and uniform measuring and reporting program within the State of Idaho.

Water Rights Accounting
New spatial tools for Water Rights Accounting aim to make an open and transparent process that can be examined by the public via the Internet.

Water Supply
Idaho water supply information is provided through the combined efforts of state and federal governmental agencies involved in water management in Idaho. Each agency brings a different technical aspect and expertise in order to provide the most extensive water supply outlook available. Find information on rivers, snow, reservoir storage, recipitation and weater, El Nino, and drought.

• River Flows for Recreationists
  Find the flow in cubic feet per second (cfs) for rivers of local interest.
• Snow Water Equivalent
  View weekly IDWR maps showing snowpack measurement in Idaho.
• Water Supply Committee
  The Idaho Water Supply Committee was created as an action element of the Idaho Drought Plan first prepared in 1990 when Idaho was in a period of sustained drought.
