Join us for the *April 29* research presentation in our spring webinar
series.

*Nutrient Loading from Headwater Streams in the Lake Champlain Basin:
Quantifying High-Flow Events*

*Date/Time:* Wednesday, April 29, 2026 - 12:00pm to 1:00pm

*Location:* Zoom (registration required). *REGISTER HERE

*Speaker:* Alex Amann, Master’s Student in the Center for Earth &
Environmental Science at SUNY Plattsburgh.

*Description: *Rapid shifts in water quality during episodic high-flow
events can disproportionately affect annual nutrient loading from forested
headwater catchments. In the Northeastern United States, observed increases
in total and extreme precipitation over the past century – trends expected
to intensify with ongoing climate change – raise concerns about how these
events drive watershed nutrient fluxes. In recent decades, several flooding
events in the Lake Champlain Basin (LCB) of NY/VT have been associated with
acute deterioration of lake water quality and traditional long-term
sampling regimes may underestimate episodic contributions. We are
collecting and analyzing high-flow event stream water from four LCB
headwater catchments in the Adirondack Mountains of New York. These
catchments vary principally in their forest management history and age,
occupying a spectrum from recently harvested timberland to old growth
forest. Our focus is on total and dissolved forms of nitrogen and
phosphorus, as well as major cations and anions. Of particular interest is
determining precipitation thresholds required to activate strong nutrient
export responses, as well as how the timing and magnitude of these exports
varies in each of the catchments during a specific event. This study will
contribute to ongoing efforts to refine watershed nutrient budgets and
inform nonpoint source pollution mitigation strategies that address
downstream water quality issues such as eutrophication under variable
hydroclimatic regimes.

Participants should expect approximately 30 minutes of presentation, which
will be recorded, followed by a facilitated, 30-minute Q&A period.

Hope to see you there!
