2011 Hydrology Project report

I was roaming through some old files today and discovered the full-year data from 2011 for the stream flow project.  This data was not posted to the web site.  In the interest of completeness I am adding it.

The ZIP file linked below contains three kinds of files.  The .hobo files are the raw data exactly as it comes off the loggers.  In order to use these files you must have a copy of Hoboware Pro software.  read more

Dye tracing and hydrology

I have added a link to a scientific paper by Ben Miller.  The paper discusses the hydrology of Carroll Cave.  As part of the project,  extensive dye tracing was performed.  The result is a comprehensive view of where the water in the cave comes from and where it goes.

You can go to the paper from the “Links” section on the right side of the web page or by going to this URL: read more

Flood events in Lower Thunder River

In early January 2018 Carroll Cave Conservancy bought and installed another stream level data logger.  The new logger is located about 150 feet downstream from Thunder Falls.

The hypothesis supporting the new logger is that Lower Thunder River floods before Upper Thunder River.  The flood progression is for Upper Thunder River to run at normal or slightly elevated levels until Lower Thunder River is completely flooded.  Only then does the water level in Upper Thunder River begin to rise. read more
