Overview

Observational study reveals key drivers of seasonal eutrophication dynamics in a freshwater reservoir, highlighting the role of thermal stratification in algal proliferation.

Key Points

To evaluate spatiotemporal variations and latent patterns in lake water quality parameters to clarify eutrophication dynamics in a freshwater reservoir.
Monitored physicochemical (temperature, pH, dissolved oxygen, turbidity, conductivity) and biological (chlorophyll-a, blue-green algae) parameters biweekly across 11 monitoring stations in Tappan Lake, Ohio, USA.
Applied over 23 principal component analyses on high-resolution, multi-temporal datasets across seasonal periods to isolate dominant drivers of water quality change.
The first two principal components captured approximately 70% of total variance, with dominant factor loadings for blue-green algae (0.949), water temperature (0.818), and chlorophyll-a (0.740).
The primary principal component explained 63% of variance in spring, 55% in summer, and 62% in fall, with vertical thermal stratification strongly influencing biogeochemical cycling.
