Lease Water Rights in Idaho
Idaho runs the cleanest on-ramp to water leasing in the West: the state Water Supply Bank. You lease your right into the Bank, the state rents it to someone who needs it, and you keep 90 percent of the rent while the right stays protected.

How water leasing works in Idaho
The Idaho Water Resource Board operates the statewide Water Supply Bank, administered through IDWR. An owner files an application to lease a right into the Bank; once accepted, the right can be rented by other users, and time in the Bank is protected against forfeiture. The Board sets a posted rental rate, currently $33 per acre foot for irrigation rentals beginning in 2025, with the owner receiving 90 percent of gross rent.
On the Upper Snake, local rental pools run under Board rules handle storage-water rentals with their own posted procedures, and negotiated private leases outside the Bank are also allowed with IDWR approval. The combination gives Idaho owners a rare thing in water: a published, state-backed floor price to negotiate above.

Leasing water in Idaho: FAQ
Can I lease my water rights in Idaho?
Yes. Idaho allows water rights to be leased, subject to approval by the Idaho Department of Water Resources. The lease has to respect other users' priority dates and, in most cases, goes through a state review before the water can legally change hands or change use. WaterLeases walks you through the path and connects you with vetted professionals in Idaho when a deal makes sense.
Who approves a water lease in Idaho?
The Idaho Department of Water Resources administers water rights in Idaho. Depending on the lease, you may need a change approval, a bank or trust filing, or district consent before the lessee can take delivery. The paperwork protects your priority date; skipping it is how owners lose value.
What is my Idaho water right worth to lease?
It depends on the basin, the priority date, the reliability of supply, and who needs the water. The Water Supply Bank pays a posted $33 per acre foot for irrigation rentals as of 2025, and negotiated private leases can clear higher where municipal or industrial demand exists. A confidential WaterLeases valuation gives you a defensible range before you talk to any buyer.
Will leasing my Idaho water right risk forfeiture or abandonment?
Done properly, no. A state-approved lease is generally treated as beneficial use, which protects the right while someone else uses the water. That protection is one of the main reasons owners lease through official channels instead of letting water sit unused.
How does the Idaho Water Supply Bank split the rent?
The Board retains 10 percent of the gross rental fee for administration and the water right owner receives 90 percent. At the posted 2025 irrigation rate of $33 per acre foot, that is $29.70 per acre foot to the owner, with the right protected from forfeiture while it sits in the Bank.
