Canadian Snowpack Forecasts Favorable
EPHRATA, WA – Columbia River hydroelectric dams see good snowpack conditions in the Canadian mountain ranges that feed spring and summer runoff water into the river. However, even in late February runoff forecasts through July were still in the 90 to 100 percent of average. Canadian forecasters are more optimistic with snow measurements at 120 to 140 percent of normal.
Intense winter storms brought high snowfall to Canadian peaks and valleys in the upper Columbia River region. But February results are about two-thirds of winter snow accumulation.
“The snowpack situation in the upper Columbia River is starting to give us a better picture of river flow conditions for 2007,” said Kevin Nordt, Grant PUD director of power management.
Power management forecasters look for additional spring snow in the mountains and also watch for the type of snowmelt occurring in May and June. In those months, high temperatures and rain can reduce snowpack needed for the rest of the year and bring flooding in some areas.
“In the weeks ahead we hope to see continued improvement in water supply. We expect that we may see average or slightly better than average water projections through the summer. Based on water flow, we make critical decisions for power generation, power purchases, fish protection, recreation and coordinated operations of Mid-Columbia River dams,” said Nordt.
Precipitation in March and April will tell the major story for this year’s Columbia River flows. In late February, Grant PUD power management forecasters were still seeing a January – July runoff forecasted at mid-90s percent as compared to last year’s over 120 percent forecast for the same period.
