There are no active Water Measurement Districts at this time.
- In October 1996, the IDWR Director created three Water Measurement Districts within the ESPA. However, those measurement districts were replaced by water districts that were created and/or expanded within the ESPA between 2002 and 2007 (refer to Water Districts 100, 110, 120, 130, and 140).
- In September 2011, the IDWR Director created a Water Measurement District in the Upper Big Wood and Little Wood River Basins. However, this measurement district was abolished in September 2013 with the inclusion of both surface and groundwater rights in Water Districts 37 and 37B.
