City of Pocatello v. Idaho
275 P.3d 845
Idaho2012Background
- Snake River Basin Adjudication initiated; City of Pocatello filed groundwater and surface water claims for in-town system and airport system.
- Pocatello asserted its interconnected wells function as alternate points of diversion for 21 groundwater rights and several surface rights under I.C. §42-1425, with conditions to protect administration and priority.
- IDWR recommended conditioning each well for alternate points of diversion to prevent injury to other rights; three rights did not receive the condition due to existing transfer No. 5452.
- Special Master adopted IDWR’s conditioning; district court affirmed; Pocatello challenged on multiple grounds including pre-1969 rights and source-change issues.
- District court determined one groundwater right (29-7770) remained irrigation, not municipal, because change required administrative transfer; pre-1987 changes were limited to certain elements.
- Priority dates for water rights 29-13558 and 29-13639 were upheld as July 16, 1924 and October 22, 1952 (with one-day adjustment for 29-13639).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Are the conditioned alternate points valid? | Pocatello argues no injury without actual third-party objections. | District court correctly upheld condition to prevent future priority injury. | Yes, conditions upheld to protect junior rights. |
| Did IDWR have authority to attach the condition absent prior similar-case practice? | IDWR changing position without rulemaking invalid. | IDWR can determine necessary administration; Rule 59(e) improper for new theory. | No; issue not preserved for appeal; not addressed. |
| Can wells serve as alternate points for surface water rights? | Wells and aquifer constitute same source; should be alterable. | Source cannot be changed under I.C. §42-1425; only place, use, etc. changes are permitted. | No; source changes not allowed under §42-1425. |
| Are priority dates properly determined for 29-13558 and 29-13639? | Evidence supports earlier dates (1905 and 1940). | Records support July 16, 1924 and October 21, 1952; no evidence for earlier dates. | Yes; priority dates sustained as recorded. |
