Nampa & Meridian Irrigation District v. Bond

Background

In 1915 an irrigation district organized under Idaho law contracted with the United States, then building the Boise irrigation project, for water and a drainage system. The district agreed to collect construction installments and operation and maintenance charges from landowners and pay them to the Government. An original drainage system was built and its cost charged as construction across project lands. Later, rising seepage ruined project lands outside the district, and the Secretary of the Interior authorized additional drainage work to be paid from operation and maintenance and shared ratably by all project users. The district refused, arguing the new charge was a construction increase barred by the Reclamation Extension Act of 1914 unless a majority agreed, and argued state law barred charging lands that received no direct benefit. The Government threatened to cut off water; the district sued to enjoin enforcement.

Reasoning

The Court addressed whether the drainage cost was construction or an operating expense. It held the work remedied harms from normal operation of a completed system, so it counted as operation and maintenance rather than new construction. The Court relied on the district’s contract saying project lands must pay the operation and maintenance charge per acre set by the Secretary. The state‑law objection failed because the system is treated as a unit supported by a common fund to which all project lands contribute ratably.

Real world impact

The decision lets the Government require the district to collect and pay the ratable drainage charges, and permits enforcement measures such as water shutoff for nonpayment. Project landowners inside the district must share operation and maintenance costs even if they do not get a direct immediate benefit from a particular repair. The ruling affirms the lower courts’ decrees and applies the contract’s operation and maintenance rules rather than the construction‑charge restriction.
