With low snowpack, what about hydro power?

Almost no measurable snow fell in Washington in February, according to the USDA's Natural Resources Conservation Service.
The agency also said more than 27 percent of its snow monitoring stations set new record low or near-record low measurements for snow water equivalent for March 1.
The water content in the snow is 8 percent of average in the Central Cascades and 7 percent of average in the Olympics.
Snowpack helps feeds the rivers that run through hydroelectric dams, a major source of power in the state.
Puget Sound Energy, with more than a million electric customers, said Thursday it's too soon to know if there will be an impact on hydropower generation or what customers pay.
Seattle City Light, Tacoma Power and Snohomish County PUD all gave more reassuring messages, saying they were not planning surcharges.
Although the snowpack is low, there has been plenty of rain, filling reservoirs behind dams to provide adequate power.
"Location, location, location makes a huge difference for us," said Scott Thomsen of Seattle City Light.
Although the mountains closest to Seattle have dismal snow, the city gets its hydro power from dams farther away where this year's snowpack is not as bad.
On the Skagit River in the North Cascades, the water content in the snow is 78 percent of average, according to City Light.
At Boundary Dam in Northeast Washington, it's 83 percent.
