Freshwater Ecology & Watershed Research

Exploring the biology, chemistry, and geography of freshwater systems in south-central Kentucky.

Every stream and pond is a meeting point. Rain falling on fields, forests, roads and rooftops carries soil, nutrients and dissolved minerals downhill; in the water, microbial communities, algae and cyanobacteria take up those nutrients, grazers eat them, and decomposers return them. Studying a creek is therefore a way of studying the whole landscape around it — and the human activity on it.

This portal is where Somerset Community College students learn the science, explore the geography, and build careful, evidence-labeled research — beginning with Allen Branch, a stream mapped a short walk from the main campus.

Centered on Somerset Community College, 808 Monticello Street (navy marker). Dashed circles: 0.5, 1 and 2 km from campus. Dark blue line with arrows: Allen Branch as mapped by USGS, about 250 m from campus at its nearest point. Dashed blue line: the mapped path downstream. All features are Mapped, not field-verified.

Research questions

All questions & projects →

Open questions students can take on. None has started yet, so every one is marked Proposed.

  • Light and habitat Proposed

    Do benthic cyanobacteria make up a larger share of the biofilm in sunlit stream reaches than in shaded reaches of the same stream?

  • Nutrients and communities Proposed

    Are nitrate and orthophosphate concentrations in Allen Branch related to the composition of its microbial biofilm?

  • Seasonality Proposed

    How do benthic biofilms in Allen Branch change from spring to fall, and do cyanobacteria become more common as flow declines?

  • Land use and stream chemistry Proposed

    Once its drainage area is delineated, how does land cover in the Allen Branch basin compare with nearby basins, and does stream chemistry differ accordingly?

How to read this portal

Evidence & citation standards →

Every geographic fact carries a label saying how we know it. A fact never moves up the list without evidence.

  • Unverified stated or suspected, not yet checked
  • Mapped shown in authoritative map data
  • Field confirmed observed on site and recorded
  • Laboratory confirmed measured in a laboratory
Before any water visit Check current Kentucky harmful algal bloom advisories. Keep people and pets out of water with surface scum, mats or unusual color. When in doubt, stay out.
