Jane S. Rogosch Cienna R. Cooper 20250311 tabular digital data https://doi.org/10.5066/P13LHQVC Stream Temperature, Intermittency, and Conductivity (STIC) loggers were deployed in tributaries of the Colorado River, TX to monitor for water presence. These loggers were deployed in a riffle and pool mesohabitat at 19 sites and recorded a measurement every six hours from June 2022 to March 2024. The loggers record temperature and relative conductivity. We calculated drying metrics derived from logger data and available discharge and precipitation data to compare characterization of stream intermittence among logger, discharge, and precipitation datasets. The data were collected to monitor water presence and absence in intermittent and perennial sites in tributaries of the Colorado River, TX. 20220607 20240313 observed Complete None planned Tributaries of the Colorado River, TX -103.0957 -97.3828 32.8427 28.9216 ISO 19115 Topic Category inlandWaters None stream intermittent STIC loggers USGS Metadata Identifier USGS:66fad2e0d34e6d68f514c521 None Colorado River Texas None.

Wilson 20250101 publication The presence and absence of water was visually assessed at points of STIC logger data retrieval and logger deployment and at those times corresponded to relative conductivity readings, given a conductivity greater than zero indicates water presence. STIC loggers lost function in temperatures greater than 130 degrees Fahrenheit. All values fell within expected ranges and appear consistent. The dataset is representative of the sites where loggers were deployed and should not be extrapolated to other sites or tributary streams.

Data were downloaded from the HOBO waterproof shuttle and compiled into one data file. Then, two fields were added to indicate the presence or absence of water based on the relative conductivity reading provided by the logger. Chapin, T. P., Todd, A. S., & Zeigler, M. P. (2014).

When calculating metrics for STIC loggers, only riffle sites were included, because of the interest in habitat connectivity.
