I've been driving Firehole Lake Drive a bit more often this week on tours, and I've noticed Lemon Spring with lowered water level twice. I know I've seen the water level down in it before, but it seemed to be maybe once a month last summer. On Tuesday, 7/17/12 it was at overflow when I went by in the early afternoon (~1:30pm) for my first tour, water level was down when I went by on my second tour (~4:45pm), and back up to overflow on my third tour (~7:30pm). Today (7/1912) when I went by with a tour (~3:15pm) it was overflowing, and then on my next tour (~5:30pm) the water level was down about two feet. Has it been varying so frequently often this summer? Karen Low -------------- next part -------------- An HTML attachment was scrubbed...
