The Pahsimeroi River is a river in Idaho, a state in the United States. It is about 59 miles (95 kilometers) long. This river flows into the Salmon River. The Salmon River then joins the Snake River, which finally flows into the big Columbia River.
Where the Pahsimeroi River Flows
The Pahsimeroi River starts in Custer County. It begins where two smaller streams, the West Fork and East Fork, meet.
The river generally flows toward the northwest. It travels through a wide area called the Pahsimeroi Valley. This valley is located between two mountain ranges. The Lemhi Range is to the east, and the Lost River Range is to the west.
The Pahsimeroi River eventually meets the Salmon River. This meeting point is near a place called Ellis, Idaho. It is upstream from the town of Salmon, Idaho.
How People Use the River's Water
The water from the Pahsimeroi River and its smaller streams is very important. People use this water for irrigation in agriculture. Irrigation means bringing water to farms to help crops grow.
Because so much water is used for farming, some of the river's main streams are completely redirected. This means they are totally separated from the main river all year long. This happens because the water is needed for irrigation.
