CharacteristicsCharacteristics
• 4th Largest river in North America• Most powerful (35,000 MW total capacity)• Drainage area = 259,000 mi2 (669,500 km2)
219,000 (84% in 7 US states) + 39,500 (Canada)• Source in British Columbia, Canada; L= 1,214 mi. (1,950 km)• Major Sub-basins: Kootenay, Pend d’Oreille; Snake; Willamette • Climate: winter (wet, mild); summer (dry, warm)• Precip: 6 – 180” (1500 – 4600 mm); max. in winter• Snow: 400” (10,000 mm) in fall - early spring• Evaporation: 35 – 55” (900-1,400mm)• Runoff and Streamflow:
• Eastern Basin = snow; Western = rain)• Discharge: Avg 275 kcfs (7,787 m3/s); Vol.: 198 maf (244 km3)• Highest recorded flow: (1894): 1,240 kfs (35,113 m3/s)

Operational Operational ConsiderationsConsiderations
• Projects within basin are operated as a system to meet regional needs for hydropower, flood risk management, etc.• System is operated for multiple purposes that can conflict with each other
•Ex. Flood risk management requires lower reservoirs in winter and spring to store flood waters; fisheries requires reservoirs to be higher
• Environmental and fisheries requirements have increased significantly in recent years due to Endangered Species Act, Clean Water Act, and other factors. • Infrastructure within the system is aging (average age is about 35 years), budget for improvements is constrained (spillways, gates, powerplants, etc.)• Awareness, interest, involvement, and expectations of stakeholders has grown significantly • Given all of these factors, operational flexibility is much more limited than in past

SummarySummary
• Columbia River is a very important resource in the regional in terms of economic development, environmental sustainability, and other areas.• Columbia River is operated as a system to meet multiple purposes• Operating requirements have become more difficult to implement as increasing demands are being placed on the river• Good coordination, communication, and working relations among the various parties involved are one of the major keys to success
