I collected data from the stream level data loggers on May 31.  Attached are
PDF files showing graphs.  There is a very large spike in the river level
between May 14 and 24.

Looking at the raw numbers from Thunder River:

5/24 at 4pm – 4 feet
5/15 at 1:15pm – 17 feet
5/17 at 6pm – Falls below 17 feet
5/20 at 1am – Hits a minumum of 3 feet, then starts to rise again
5/21 at 2:15am – Hits 21 feet
5/24 at 8:45pm – Falls below 2 feet.

The data for UL2 shows rise and fall times within hours of the Thunder River times.
