Stream Ecology Institute

July 7–13, 2024

This summer, search under rocks for crawdads and salamanders, test stream waters for salinity, pH and dissolved oxygen and learn how those elements interact with living and non-living components of stream systems. At this summer institute, you’ll explore how a fish, an insect, algae and even an old tire, influence each other and are affected by one another in a continuum — from small streams to large rivers.

You’ll engage in learning experiences about the environment and long-term ecological studies, as well as explore career possibilities in science and ecology.

Students entering grades 10–12 are invited to register.

About the Program

Eager to begin your studies and to investigate:

  • If plants affect the presence of aquatic invertebrates?
  • How the material in the stream bed influence aquatic communities?
  • The correlation between stream flow, water temperature, dissolved oxygen, and fish populations?

For a full week, you will be taught the fundamentals of water quality, macroinvertebrate and fish sampling, and identification. You’ll get plenty of hands-on experience using the latest equipment and methods employed by professionals in the field of aquatic ecology.

On the final day, you will present your findings, using the latest in computer technology, to a panel of science educators and natural resource professionals.

Join us for this exciting college life experience while learning the basics of stream ecology!


At Stream Ecology Institute, you’ll get a chance to:

  • “Immerse” yourself in the Susquehanna River Basin ecosystem to learn about numerous components of the streams.
  • Learn how water movement, fish, invertebrates, vegetation, bacteria, water chemistry and pollution affect the creek.
  • Explore regional creeks from the bottom up and develop your own study to investigate an aspect of the creek that interests you.

Other highlights include:

  • Boating
  • Hiking
  • Picnicking in state parks
  • Visit to Penn’s Cave
  • Daily field trips
  • Sample collections in rivers, creeks, and small streams
  • Electrofishing in local streams
  • Study of headwater streams
  • Final research presentations for families
