WashFormed by a prehistoric landslide, Bull Run Lake sits above
the headwaters of Bull Run River, which is a highly productive
source of fresh water for the City of Portland.

Delivering reliable, high-quality water requires a delicate balance between water supplies and customer demands. While water managers continually strive to maintain this supply-and-demand balance through long-term water resources planning and demand management, new challenges exist due to the impacts of climate change, putting the world's water resources at risk.

From heavy rainfall events and flooding to prolonged drought, watersheds throughout the world are experiencing greater variability in weather patterns. These extreme events also are impacting water infrastructure systems. Solely relying on historical data to predict future precipitation, snowpack, runoff and stream flow is no longer is practical. In addition to climate change, population growth, increased water demands, water quality concerns and endangered species issues make the availability of water resources and impacts to water infrastructure a critical concern for water providers.

The Water Utility Climate Alliance (WUCA) is dedicated to collaborating on climate change issues affecting drinking water utilities. WUCA is enhancing climate change research and improving water management decision-making to ensure that water utilities will be positioned to respond to climate change and protect our water supplies.
