Guidelines and procedures for collecting water measurement data and reporting the information to the Idaho Department of Water Resources have been developed in order to have an orderly and uniform measuring and reporting program within the State of Idaho.
The information below assists in measuring and reporting diversions pursuant to various water measurement orders issued by IDWR. The following links and guidelines are also applicable and useful for water measurement requirements within water districts.

Water Measurement Information Systems (WMIS)
The WMIS and Water District Diversion Data applications are used by IDWR, watermasters, and district hydrographers to enter and retrieve delivery measurements and estimations of annual water usage. The WMIS database primarily contains information related to irrigation wells on the Eastern Snake River Plain Aquifer, but it is also used for other ground and surface water points of diversion for which annual delivery totals are recorded. The Water District Diversion Data database contains daily diversion records for certain surface water diversions and some ground water diversions for which regular flow rate measurements are taken. For further information, please contact the Water Distribution Section at (208) 287-4958.
