The stream flow data from full year 2013 is now collected and graphed.  The attached ZIP file contains all of the raw data in TXT format plus PDF graphs of each major data set.  If anyone has HoboWare Plus (not a free program) and wants the true raw data, let me know and I will send it out.

There was one major flood event in 2013.  In early August the area received almost 18 inches of rain in just a few days.  As expected the stream levels in the cave rose quite rapidly.  The rain began on August second and continued through August 9.  The silo rain gauge recorded 17.88 inches of rain in this period.

Thunder River started rising about noon on August 5.  After a brief peak just over 3 feet and a bit of decline, the serious flooding started in the early morning of August 7.  By 3:00pm on August 7 the level was over 17 feet.  There were a few minor fluctuations, with the peak of 18.6 feet occurring at 6:00pm on August 8.  It stayed at that level for about two days, then on August 10 it began to fall.  It went under 2 feet in the very early morning of August 13.

Both Carroll River and the stream in UL2 showed similar rises.  Carroll River peaked at just over 3.6 feet at 7:00pm August 9.  UL2 peaked at about 12.2 feet at the same time.

There were other minor changes in the stream level, amounting to less than a foot change.
