Last summer, a minnow called the laurel dace faced extinction when drought dried up the few streams where it lives in southeastern Tennessee. Conservation biologists rescued two populations to keep at the Tennessee Aquarium, and now two Odum School graduate students are working with other researchers and local residents to save the endangered fish.
Amy Rosemond and Catherine Pringle were inducted into the Fellows of the Society for Freshwater Science at a recent meeting in Puerto Rico. Several members of the Pringle Lab also held a two-part panel discussion—“Hydrologic connectivity and watershed conservation: a session in honor of Dr. Cathy Pringle”— to highlight the knowledge amassed during 30 years of working with Pringle, who supervised 24 doctoral and 22 master’s students over her career.
Valeria Aspinall was at the Tapir Valley Nature Preserve in northern Costa Rica the day an expert herpetologist declared that the tree frog living there is a distinct species, something that had not been recognized by science. Aspinall is now at the Odum School of Ecology working on a master’s degree with a Spencer Fellowship and conducting research that she hopes will protect the very rare, critically endangered frog, which has only been found in a 20-acre wetland within the larger nature reserve adjoining Tenorio Volcano National Park.
Athens, Ga. – “Purified water,” “reused water,” “recycled water”—these terms mean exactly the same thing. Even though all three refer to water that’s been treated to the highest drinking water standards, research has shown that people much prefer the idea of consuming purified water to reused or recycled water. A recent study from a team of University of Georgia River Basin Center affiliates has for the first time put a dollar value on that preference.
The Land Conservation Clinic and the River Basin Center have released the updated Local Wetlands Protection Primer, a guide to help protect wetlands that provide flood prevention, water quality improvements, protection from erosion, support for fisheries and biodiversity, and opportunities for recreation activities.
As an undergrad at the University of Benin in Nigeria, Justin Jimawo studied tropical zooplankton, the tiny organisms that live near the surface of streams and ponds.
ATHENS, GA – Interdisciplinary knowledge is a critical aspect of solving big environmental problems. That’s why, for the 2025 Georgia Water Resources Conference, we brought everyone together. We do mean everyone: ecologists, hydrologists, engineers, geoscientists, lawyers, anthropologists, consultants and certified fish enthusiasts.
Athens, Ga. – Six graduate student affiliates of the River Basin Center have been named recipients of John Spencer research grants for 2025. This year’s awards will provide a total of $10,000 to support a range of projects that contribute to water sustainability and resilience across the southeastern United States and beyond.
Few resources are as vital as water. But as human activity continues to shape urban rivers, that refreshing dip in the stream, summer kayaking trip, or glass of ice water can be harder to achieve. This is why every year, on March 22, we observe World Water Day: a tradition started by the United Nations in 1993 to highlight the importance of clean, accessible water. Sustainable water management is important not just for the environment, but for the 8.2 billion people that rely on water.
Something “clicked” for Mackenzi Hallmark while doing fieldwork in northwest Georgia.
The current Odum School of Ecology graduate student and 2024 James E. Butler Fellow was measuring water quality in the Etowah and Conasauga rivers, part of her role as a research technician for the school’s River Basin Center (RBC). She became enamored with the biodiversity she encountered, from freshwater mussels to fish species like the amber darter.
