Rivers Conservation Plan

The Wissahickon River Conservation Plan (RCP) was completed in 1999, supported by funding from DCNR and the William Penn Foundation. Based on information collected from a diverse array of stakeholders, the plan presents a number of ways to improve not only the creek, but quality of life for residents as well.

Comprehensive Characterization Report

Completed in 2007, The Comprehensive Characterization Report (CCR) for Wissahickon Creek Watershed contains detailed technical information about land use, geology, soils, topography, demographics, meteorology, hydrology, water quality, ecology, fluvial geomorphology, and pollutant loads in the watershed.

Act 167 Plan

The Wissahickon Act 167 Plan was completed in 2014 under the leadership of Montgomery County and the Philadelphia Water Department. Under requirements of the Pennsylvania Stormwater Management Act of 1978, the main objective of this plan is to control stormwater runoff on a watershed-wide basis

Stream Assessment Study

The Lower Wissahickon Creek Watershed Assessment Study was completed in 2010 to comprehensively evaluate the fluvial-geomorphic characteristics of each sub-watershed within the Lower Wissahickon Watershed, which encompasses the Philadelphia portion of the Wissahickon Creek Watershed. Fluvial geomorphology combines geology, hydrology, ecology and hydraulics to better understand the relationships between watershed characteristics and streams as well as the dynamic interaction between streamflow, sediment and floodplains. Understanding these concepts is instrumental to the design and implementation of stream restoration projects as well as certain aspects of stormwater management.
