Schuylkill River Project

Lofty Creek

Lofty Creek in the headwaters of the Little Schuylkill River

Our Schuylkill River project is an effort to describe stream water quality throughout the 1900-square mile Schuylkill River basin in southeastern Pennsylvania. We assess stream condition by sampling the macroinvertebrates (mostly insects, crustaceans, mollusks and worms) that live on the stream bottom.

The presence of particular types as well as their relative abundances are combined with knowledge of the ability of the various types to withstand pollution to come up with a water quality “score” for each site. Water quality scores identify poor quality streams in need of mitigation, high quality streams worthy of special protection, and fair quality streams that may deserve intervention to prevent them from becoming poor quality streams.

Overview of Web Pages

This website presents the results of 12 years of study, from 1996 to 2007. Included are data from 19 long-term study sites on major tributaries that are sampled each year. These sites provide a current and long-term assessment of watershed health throughout the basin. An additional 120 sites, located upstream from the original 19 sites and sampled in one year only, provide a more complete picture of conditions within the major tributaries within the Schuylkill basin. Throughout this website, sampling sites are color coded to indicate water quality conditions, with blue signifying “good”, yellow “fair” and red “poor”.

The site is organized into pages as follows:
