The Potomac River is a vital resource for millions. Through science, collaboration, and education, ICPRB is ensuring its health for future generations.

Excerpt from the “River Report” section of the 2024 Annual Report:

Records were broken. The D.C. region experienced its longest dry streak of 38 days without significant rain. According to NOAA, October was one of the warmest and driest on record for the entire United States. The Potomac basin upstream of Washington, D.C. received only 0.8 inches of rain during that month, which is 2.2 inches below normal.

Scientists are seeing a trend in increasing average temperatures year after year. Heat-induced moisture loss could lead to longer, more widespread, drought conditions.

These increases are not limited to the ambient (air) temperature. Recent data analysis by ICPRB has seen an increase in water temperatures over the past century. Average water temperatures are increasing across all seasons with winter months seeing the fastest climb.
