Notes From the Road: Episode 1

Catching the Anomaly: A Site Identification Trip Through the Rock River Watershed

by Martha Gerig, PhD

Earlier this month, Shawn Meyer, Waterborne Lead Scientist and Manager, and I met in Dixon, IL, and spent two days winding our way from the border of Wisconsin to the Mississippi River. We followed the paths of rivers and streams that make up the lower Rock River watershed with a straightforward goal: to identify potential river sampling sites that would help us better understand nutrient loss across this priority watershed in Illinois’ Nutrient Loss Reduction strategy. The purpose of this particular trip was to identify sites that would capture the most representative "signal" of nutrient loads moving through the watershed, while ensuring that locations were safely accessible for consistent, repeatable sampling efforts.



We focused on bridge crossings with existing U.S. Geological Survey (USGS) gaging stations to take advantage of publicly available data. These gages are like time capsules, recording years (and sometimes decades) of streamflow data. Visiting these spots in person helped us assess accessibility and site conditions for future monitoring, but it also offered a rare on-the-ground view of something we usually study on screens and spreadsheets: the rivers themselves.


And what we found was striking. Every site we visited—whether a small tributary or the mainstem of the Rock River—was running exceptionally low. Exposed riffles, sluggish side currents, and wide stretches of visible riverbed provided visual context for what were abnormal levels. When we checked the USGS data later, it confirmed our observations: these were some of the lowest streamflows on record for this time of year...

Bats: Hero Pollinators and Halloween Stars

When most people think of bats at Halloween, spooky images and haunted houses are likely to come to mind. Surely a by-product of literature and Hollywood horror movies, the bat's image over the years has landed it solidly on the "scary" side of the animal kingdom. Yet dangerous and nefarious is far from an accurate portrayal of an intriguing mammal that plays a vital role in our ecosystems, especially as a pollinator.



The reality is that bats are critical pollinators in many ecosystems, particularly in tropical and subtropical regions, including parts of the United States. Approximately 500 species of bats worldwide feed on nectar, pollen, or fruit, transferring pollen as they move between flowers. In the U.S., nectar-feeding bats such as the Mexican long-tongued bat and lesser long-nosed bat play a critical role in pollinating plants like bananas, agave, cacti, and various desert wildflowers. It's fair to say that the Tequila industry would struggle without bats!


Bats are most active at night, making them perfect Halloween icons. They are especially effective pollinators because they travel long distances, visit multiple flowers, and often feed on flowers that are inaccessible to other pollinators. Beyond food crops, the bat helps to maintain the health of forests and wild landscapes, and their daily activities ensure genetic diversity and plant reproduction within these habitats.


So this Halloween, rather than fear the bat, instead take a moment to thank this delicate creature for its contributions to our food chain and ecosystems!
