The mission of the National Park Service (NPS) is "to conserve unimpaired the natural and cultural resources and values of the national park system for the enjoyment of this and future generations" (NPS 1999). To achieve that goal, and as a result of the Natural Resource Challenge, 270 parks in the national park system were organized into 32 Inventory and Monitoring (I&M) Networks. One of those networks, the Eastern Rivers and Mountains Network (ERMN), includes nine parks in New Jersey, New York, Pennsylvania, and West Virginia.
This report was intended to provide preliminary results to the Natural Resource Manager at Allegheny Portage Railroad National Historic Site (ALPO) and Johnstown Flood National Memorial (JOFL).
This 'Level 1' water quality inventory was conducted for streams located within Allegheny Portage Railroad National Historic Site (ALPO) and Johnstown Flood National Memorial (JOFL), National Park Service (NPS) properties, from April 2004 to November 2004.

During 2008, the ERMN began collecting data using the Wadeable Streams Monitoring Protocol, which addressed the benthic macroinvertebrate and water quality vital signs. This report summarizes the status of benthic macroinvertebrate communities and water quality in selected wadeable streams throughout parks in the Northern Appalachians Ecoregion of the ERMN (i.e., Allegheny Portage Railroad National Historic Site, Delaware Water Gap National Recreation Area, Johnstown Flood National Memorial, and Upper Delaware Scenic and Recreational River). Data collected since 2008 (with emphasis on data collected during 2010) are presented and discussed. All data were collected following methods detailed in the Wadeable Streams Monitoring Protocol (Tzilkowski et al. 2009).
