Bear Lake Watch Info


MESSAGE FROM PACIFICORP
PacifiCorp Message in Black / [SplashBack commentary in Blue]
EMAIL MESSAGE FROM PACIFICORP: [Which we do very much appreciate; this type of partnership and information -sharing hasn’t always existed]

PacifiCorp has set the PacifiCorp Target Elevation (PTE) for Bear Lake to 5,917.4 feet and is adjusting the Bear Lake Outlet Canal flows to achieve the PTE [PTE: This is the elevation they think the lake should be on April 1st in order to best manage the spring runoff]
(Bear Lake is currently at 5,918.12 feet).

 This target elevation is consistent with current available forecasts and hydrologic conditions,
including basin-average snow water equivalent [the SWE from the SNOTEL graphs we show you] which is slightly above normal at 118% of average for February 18th [there’s that ‘Normal” again] and 89% of the typical maximum snowpack observed around April 1st (see plot below). 
PacifiCorp personnel routinely evaluate the target elevation and may update it and adjust the Bear Lake Outlet Canal flows to target the revised PTE.
