<span style="font-family: "Times New Roman", serif; font-size: 12pt; color: rgb(0, 0, 0);">Maryland regulatory agencies are considering establishment of a TMDL for stream temperature. Toward that end, there is an interest in quantifying the effects of stormwater
BMPs vs uncontrolled storm runoff to determine impacts on stream thermal regime. To assist in this assessment, we have deployed 204 HOBO TidbiT MX 2203 temperature data loggers over all 16 km of daylighted segments of Dead Run in Baltimore County, MD as a
case study. Sensor spacing varies between 50 and 100 m, with additional sensors placed ~2 m downstream of every stormwater management facility. The sensors are secured to the streambed using a system of rebar, snap hooks, and zip ties. Data are recorded every
5 minutes, with data collection having started in December 2021. Data retrieval via Bluetooth technology requires hiking the stream and removing the sensors for download. All downloaded data are stored at UMBC in a relational database. A GIS-based algorithm
has been developed to video-animate the data. Quantitative analysis reveals that the greatest contrast between baseflow temperature and peak runoff temperature is observed at stormwater pipe outfalls draining buried headwater streams, where the drainage system
collects hot runoff via street inlets during storms. The stream temperature variability due to storm runoff collapses moving toward the main stem outlet. Contributions to stream thermal load from stormwater management facilities appear to be no greater than
that from the abundant outfalls from pipes draining directly connected impervious area. This work has been supported by Chesapeake Bay Trust.</span></p>
