Back in January during the regular data logger service trip, I had trouble downloading data from the logger in UL2. To further diagnose the problem, I took the logger out of the cave. It turned out to have a low battery. We sent it in for a battery replacement. It was returned in early March and placed back in the cave during a trip on 20 March.
The stream flow data and graphs for 2021 are attached to this post as a ZIP file. Download and open this file to see the data. All of the graphs are in .PNG format. Raw data is also included, both as comma-separated values (CSV) files and as .hobo files.
There were no big flood events during 2021. Thunder River reached just under 4 feet in January, and never rose above 2.5 feet for the remainder of the year.

This is the annual summer trip to download data from all of the data loggers in the cave. The loggers only hold about 7 months of data, so we visit them every 6 months or so.
I drove to the silo campground Friday afternoon, arriving about 4:00pm. After parking the camper, I started the lawn mower. The grass was not all that high except right nround the camper. I mowed in front of the silo, around the picnic table and around my camper and truck. I also ran a string trimmer. My string trimmer is a small battery-powered device that just does not have the power to deal with tall grass such as what is under the picnic table.
The Stream Flow Project is complete for 2020. The ZIP file linked below contains all of the raw data along with graphs.
There was only one major flood in Carroll Cave during 2020. That flood occurred on 12 January. The stream level at the ladder reached about 12 feet, and below Thunder Falls it reached almost 21 feet. Other minor floods happened throughout the spring, and there was one minor event in October.
