Is Blue Mountain Lake low for this time of year?
Compared with every October in our records, the current level is higher than 3% of them, which we classify as low for this time of year. Seasonal comparison matters more than the raw number, because most reservoirs draw down predictably through late summer and refill over winter and spring.
Why is Blue Mountain Lake low right now?
Reservoir levels move for four main reasons: rainfall and runoff into the basin, releases through the dam for downstream water supply, power generation or flood control, evaporation during hot months, and seasonal drawdown schedules set by the operating agency.
