(Al Hartmann | Tribune file photo) Bert and Christine DeLambert look down onto their cattle ranch along the long valley in Main Canyon in Uintah County Thursday Dec. 8, 2016. The DeLamberts' land is immediately below the PR Spring tar sands mine on the rim about three miles away. His springs have gone dry in the years since U.S. Oil Sands drilled exploratory holes and water wells. The DeLamberts unsuccessfully tried to block a water rights transfer to U.S. Oil Sands that would allow them to pump more groundwater.
