Regional water supply forecast below average

The Columbia Basin's water supply forecast predicts a runoff at 86% of normal, indicating a below-average situation for the region. Experts, including Kurt Miller from the Northwest Public Power Association, express relief that conditions are better than last year, though they remain below optimal levels for hydropower and fisheries. Snowpack levels vary significantly across the region, with Clearwater at 95%, Salmon River at 109%, and the upper Columbia River basin at just 65% of average. Dry weather this April has led Idaho Power Company to adjust water flows from Brownlee Dam to mitigate lower runoff. Craig Mountain is particularly affected, with local irrigation districts reporting insufficient snow accumulation.

Jonathan Ebel from the Idaho Department of Fish and Game stresses that dry conditions hinder soil moisture, affecting water availability for crops and fish. The interplay of winter snow and spring weather is critical, as cooler temperatures can help preserve snowpack. As the region prepares for summer, experts remain vigilant about managing water resources effectively.
