Clearwater River River Levels

Last Updated: December 5, 2025

The Clearwater River is a major tributary of the Snake River, spanning approximately 74 miles in length.


Summary

Total streamflow across the Clearwater River was last observed at 11,332 cfs, and is expected to yield approximately 22,476 acre-ft of water today; about 80% of normal. Average streamflow for this time of year is 14,207 cfs, with recent peaks last observed on 2022-06-12 when daily discharge volume was observed at 263,553 cfs.

Maximum discharge along the river is currently at the Clearwater River At Spalding Id reporting a streamflow rate of 4,430 cfs. However, the streamgauge with the highest stage along the river is the Clearwater River At Red Lake Falls with a gauge stage of 4.83 ft. This river is monitored from 7 different streamgauging stations along the Clearwater River, the highest being situated at an altitude of 3,909 ft, the Clearwater R Ab Trap Cr Nr T Falls.

A clearwater river is classified based on its chemistry, sediments and water colour. Clearwater rivers have a low conductivity, relatively low levels of dissolved solids, typically have a neutral to slightly acidic pH and are very clear with a greenish colour. Clearwater rivers often have fast-flowing sections.The main clearwater rivers are South American and have their source in the Brazilian Plateau or the Guiana Shield. Outside South America the classification is not commonly used, but rivers with clearwater characteristics are found elsewhere.Amazonian rivers fall into three main categories: clearwater, blackwater and whitewater. This classification system was first proposed by Alfred Russel Wallace in 1853 based on water colour, but the types were more clearly defined according to chemistry and physics by Harald Sioli (de) from the 1950s to the 1980s. Although many Amazonian rivers fall clearly into one of these categories, others show a mix of characteristics and may vary depending on season and flood levels.
