 This year also marks the first year of implementing the Lake Tahoe Destination Stewardship Plan, an award-winning plan that establishes a vision for outdoor recreation and tourism in the region. I'm Sophia Holm, KUNR News. Temps will be going into the 100 degree range starting the 4th of July weekend and then at near or above 105 degrees as the weekend progresses through Monday the 9th. Excessive heat warning is in effect until then.
