Continuous Stream Monitoring Program

The purpose of the Countywide Stream Assessment Program (CSAP) of the Dauphin County Conservation District (DCCD) is to collect data to determine the present condition of Dauphin County’s streams.  The CSAP will document and measure changes in stream conditions occurring over time.  In addition, CSAP will provide some evaluation of the factors affecting stream condition in order to protect, maintain, and restore stream conditions to meet designated uses. 

The results of this 5 year study are intended to present water quality issues to the public in order to promote and support initiatives that increase direct participation in stream stewardship and the reduction of water pollution.  The study also focuses DCCD programs and prioritizes the most critical stream protection needs in the County’s watersheds.  To improve public education, this document contains information regarding the character of the County’s watersheds and issues found within them. 

Data has been collected for the CSAP every year since 2004, with 2008 being the last year included in this report.  Upon completion, the results were reviewed and made understandable and accessible for all interested groups and individuals.  Yearly assessments are continuing to note changes that are occurring.

Background on the Stream Health Report

Background information on the study design, stream classifications, common pollution sources, and monitoring methods can be found in the Stream Health Report Background.

Study Result Within the Northern Dauphin County Watersheds

Stream health results for Mahantango Creek, Wiconisco Creek, Armstrong Creek, Powell Creek, Clark Creek, and Stony Creek can be found in this section of the report.  Results are organized by watershed, providing background information about stream classifications, sample site locations, and stream health scores based on macroinvertebrate communities.

Study Result Within the Southern Dauphin County Watersheds

Stream health results for Fishing Creek, Paxton Creek, Spring Creek (West), Swatara Creek, and Conewago Creek can be found in this section of the report.  Results are organized by watershed, providing background information about stream classifications, sample site locations, and stream health scores based on macroinvertebrate communities.

Conclusions and Recommendations

Context of the results can be found in the conclusion of the report, including a discussion on the need for further analysis, and overall watershed health based on sample site scores.  Furthermore, Recommendations to protect and improve water quality are described. This section of the report also provides appendices, detailing technical descriptions of study methods, along with figures, tables, and maps.
