FINDINGS OF THE WATER 1991 SCENIC RIVERS QUALITY MONITORING PROGRAM REPORT NO. 14 DRBC/NPS COOPERATIVE MONITORING PROGRAM DELAWARE RIVER BASIN COMMISSION IN COOPERATION WITH THE NATIONAL PARK SERVICE MARCH 1992 Report prepared by the Delaware River Basin Commission staff, Gerald M. Hansler, Executive Director. Warren Huff, Richard Albert, and Todd W. Kratzer were the principal authors. Pauline Ditmars provided Word Processing support. The 1991 Scenic Rivers Water Quality Monitoring Program was a cooperative effort between the Commission and two units ofthe National Park Service. Overall design and management of the program was performed byTodd W. Kratzer (Delaware River Basin Commission) with assistance from Deborah Drelich (Delaware Water Gap National Recreation Area). Planning for the program was assisted by Richard Albert with the Delaware River Basin Commission, Elizabeth Johnson with the Delaware Water Gap National Recreation Area, and Malcolm Ross Jr. with the Upper Delaware Scenic and Recreational River. Persons who particpated in the field program were Don Miller, Chris Halloran and Cyndie Faunce with the Commission; Deborah Drelich, Dirk Amtower, Ramona Abraham, Mike Croll, and Marion Damiano-Nittoli with the Delaware Water Gap National Recreation Area; and Bill Weber, Rhonda Moore, Joe Sargent, Cliff Daniels, Ralph Huebner, and Vince Pareago with the Upper Delaware Scenic and Recreational River; and Suellyn Shupe and Sylvia Sievers with the Student Conservation Association.

The program is conducted by the Delaware River Basin Commission iDRBC) and the National Park Service (NPS) in the Upper Delaware Scenic and Recreational River (UDSRR) and the Delaware WaterGap National RecreationArea (DWGNRA). The program determines the status ofwater quality in the Upper and Middle Delaware Scenic and Recreational Rivers; the eight miles ofthe Delaware that separate these two components ofthe National Wild and Scenic Rivers System; and many of the 70 plus tributaries that flow into the Delaware River. The 1991 program was the eighth year of the DRBC/NPS monitoring program. The cooperative program operates under a quality assurance plan approved by the U.S. Environmental Protection Agency. Earlier reports of the program are available. PROGRAM OBJECTIVES The 1991 Scenic Rivers Monitoring Program targeted four objectives in 1991: 1. Continue past baseline water quality monitoring; 2. Continue obtaining water quality data needed for the development of a scenic rivers water quality model and to define existing water quality along the mainstem and at tributary control points; 3. Continue tributary flow gaging efforts; and, 4. Conduct special investigations, where needed. OVERVIEW OF PROGRAM The 1991 DRBC/NPS Scenic Rivers Monitoring Program made over 600 station-visits to 77 sites in the scenic rivers region. During the sampling season, 33 tributaries (44 sites) and 28 Delaware Riverlocations (33 sites) weresampledup to tenormore times each. These station-visitswerepart of the baseline monitoring effort. In this effort, data were collected for dissolved oxygen, air temperature, water temperature, Ph, conductivity, fecal coliform and otherparameters. These data for river and tributary sites are presented in Appendices A and C, respectively. At selected sites, nutrient and biochemical oxygen demand samples were also taken for mathematical model development and for supplementing the existing data base for defining existing water quality. Figures 1 and 2 show the locations of these stations and Table 1 provides location descriptions. Macroinvertebrates (aquatic insects) were collected at 12 sites: 1 each in the East and West Branches of the Delaware River near Hancock, N.Y.; 4 in the UDSRR, 5 in the DWGNRA, and 1 in the intervening reach of the Delaware River. Macroinvertebrates serve as a surrogate for toxic analyses and an indicator of long-term changes in water quality. Macroinvertebrate data will be presented in a separate report.
