Exert from Don Willis Lassen County Surveyor. May 1, 2020 “The current elevation is at 5095.81 ft. as measured at the deep-water ramp at Gallatin. This puts the level down 1.34 ft. from where it was at one year ago at this time. “ We will do fine all season at the low water ramp but spalding ramp might not last as long for larger boats.
