Seepage Lake Water Quality Field & Laboratory Assistant

Employer: Cassandra Ceballos ( she/her)


The Stanley Lab is hiring one enthusiastic and resourceful undergraduate student to work as a field/laboratory assistant this summer. The position is based at the Center for Limnology’s Hasler Lab (Madison) and involves local travel to sample lakes. This ongoing research seeks to determine if and how rising lake water levels have changed water quality and biological organisms of a seepage lake (Fish Lake, Wisconsin). Decreasing lake and reservoir water levels associated with droughts can have dramatic effects on these ecosystems, but less is known about possible consequences of increasing water levels for lakes in regions that are becoming wetter, such as southern Wisconsin where large rainfall events and total annual precipitation have been increasing over the past 2-3 decades. Fish Lake’s surface water elevation steadily increased by 1.8 m since 1975 and the lake ultimately connected with an adjacent shallow lake. The student hired for this position will provide support for weekly sampling to collect water and sediment samples on site and analyze water quality parameters in the laboratory. The student must be willing to have occasional long days, work in potentially adverse weather conditions, and be comfortable working on a boat. Experience trailering and driving small watercraft is desirable but not required.

Having students with different life experiences and backgrounds is critical to ensure the exchange of diverse ideas that is called for in training tomorrow’s scientists. Because we are actively working to increase diversity and inclusivity in our discipline, underrepresented groups are especially encouraged to apply.
