To direct the Secretary of the Interior to conduct a comprehensive study of the Rathdrum Prairie/Spokane Valley Aquifer, located in Idaho and Washington.

This bill, introduced in 2002, directs the Department of the Interior to conduct a comprehensive scientific study of the Rathdrum Prairie/Spokane Valley Aquifer, which spans the border of Idaho and Washington. The goal is to create a detailed computer model of the aquifer to help both states develop a shared, data-driven understanding of how much water is available and how it moves underground. For local residents, this legislation aims to ensure more reliable water management and help prevent future legal disputes between the two states over shared water resources.
