Water Supply Bank Administration

General Information

The Board’s water supply bank is administered by staff at the State Office of the Idaho Department of Water Resources while rental pools are administered by Water District staff and rental pool local committees, which are frequently Water District advisory committees. Both the Board’s bank and the various rental pools are administered pursuant to Idaho Code §§ 42-1761 through 42-1766 and Water Supply Bank rules, as well as rental pool procedures.

Rental Pool Administration

Water users looking to lease their water rights to regional rental pools should contact the water district watermasters responsible for rental pool administration.

IDWR State Office staff review applications to lease and rent water rights year-round. Rental applications are prioritized for processing between November through March. Applications are typically processed within 30-60 days but may take longer depending on the timing, request, and location. Applicants should submit their lease and/or rental applications several months in advance of the intended start of their use, or non-use, of water. Refer to the processing calendar below for more information on priorities and timelines. 

Shoshone-Bannock Tribal Water Supply Bank

The Shoshone-Bannock Tribes operate a Water Supply Bank for the lease of Tribal water stored in Upper Snake River federal reservoirs.  

Transaction Processing

The Water Supply Bank operates year round. However, administrative activity is least active during summer months when IDWR staffing resources are reallocated to other priority activities of the Department. Seasonal objectives dictate programmatic priorities—lease applications are most actively processed during fall months while rental applications are prioritized for processing during winter and spring.

On the Water Supply Bank Calendar, the priority level color bars represent the dedication of staffing resources to a process. High priority signifies that significant staffing resources are dedicated to a process while Standard priority indicates limited staffing resources are dedicated to a process.
