  • The Delaware Floodplain
    The Delaware Floodplain Final Draft Report September 2011 prepared by: Gerald J. Kauffman Andrew R. Homsey Water Resources Agency Institute for Public Administration School of Public Policy & Administration College of Arts & Sciences University of Delaware - www.ipa.udel.edu serving the public good, shaping tomorrow’s leaders Introduction Situated on the Delmarva Peninsula between the Delaware Bay and Chesapeake Bay, Delaware is the lowest state in the United States, with a mean elevation of just 60 feet above sea level. Vulnerable to flooding from rising sea levels and ocean-fueled tropical storm systems, coastal Delaware is one of only three states located on a peninsula. Delaware floods originate along the hilly, rocky Piedmont streams in northern New Castle County and from the tidal bay and Atlantic Ocean. The 100-year Floodplain More than 331 square miles, or 17 percent of Delaware’s landmass, lie within a mapped 100-year floodplain. The distribution of floodplains in the three Delaware counties is similar, ranging from 16 percent to 18 percent of the land. Table 1. Area of the 100-year Floodplain in Delaware County 100-year Floodplain (sq mi) Portion of County Landmass New Castle 67 16% Kent 94 16% Sussex 170 18% Road Miles in Floodplain Approximately 621 road miles are in the 100-year floodplain in Delaware. New Castle, Kent, and Sussex Counties contain 128, 75, and 418 road miles in the 100-year floodplain, respectively. Watersheds with the largest mileage of floodplain roads include the Christina River in New Castle County (44 miles), Murderkill in Kent County (16 miles), and Indian River Bay (106 miles).

  • MURDERKILL RIVER WATERSHED REVISED NUTRIENT and DISSOLVED OXYGEN Tmdls
    Delaware Department of Natural Resources and Environmental Control MURDERKILL RIVER WATERSHED REVISED NUTRIENT AND DISSOLVED OXYGEN TMDLs Prepared by: HDR|HydroQual KCDW – 178287 March 2014 i PREFACE As required by the Federal Clean Water Act, the Delaware Department of Natural Resources and Environmental Control (DNREC) is responsible for implementing water quality monitoring and assessment activities in the State and also for establishing Total Maximum Daily Loads (TMDLs) on impaired State surface waters as indicated on the State’s 303(d) List. On May 12, 2005, the Cabinet Secretary of DNREC issued Order No. 2005-W-0025 adopting amended Total Maximum Daily Load (TMDL) Regulations for nutrients and oxygen consuming compounds for the entire Murderkill River Watershed. Since promulgation of the 2005 amended TMDL, a multi-year monitoring, research and modeling study of the Murderkill River Watershed by DNREC and other cooperating agencies and institutions resulted in proposing scientifically-based, site-specific dissolved oxygen (DO) criteria and nutrient targets for the tidal Murderkill River. This multi-year effort necessitated revisions to the 2005 TMDL that will comply with the proposed site-specific DO criteria and nutrient targets for the tidal Murderkill River. The proposed revisions to the Murderkill River Watershed nutrient and DO TMDL will be presented during a Public Hearing to be held on April 29, 2014 at the DNREC main office in Dover. All comments received before and during the Public Hearing process will be considered by DNREC. Based on the comments received, the report may be modified accordingly. i CONTENTS Section Page 1 INTRODUCTION ......................................................................................................................... 1-1 1.1 303(D) LISTED WATERBODIES ...............................................................................

  • Water Quality Trends Along Delaware Streams from 1970 to 2005
    WATER QUALITY TRENDS ALONG DELAWARE STREAMS FROM 1970 TO 2005 Gerald J. Kauffman, Andrew C. Belden, and Christina L. Callahan1 ABSTRACT: Water quality trends from 1970 through 2005 were detected using the Seasonal Kendall test along 30 streams in the State of Delaware. Twenty-four streams flow east to the Delaware Bay and 6 streams flow west towards the Chesapeake Bay. Water quality improved or was constant at 69% of stations since 1990 and at 80% of stations since 1970-1980. Dissolved oxygen improved or was constant at 22 of 30 streams since 1990 and 8 of 25 streams since 1970-1980. Total suspended sediment improved or was constant at 21 of 28 streams since 1990 and 11 of 11 streams since 1970-1980. Enterococcus bacteria improved or was constant at 24 of 30 streams since 1990 and 25 of 27 streams since 1970-1980. Total Kjeldahl nitrogen improved or was constant at 14 of 29 streams since 1990 and 24 of 24 streams since 1970-1980. Total phosphorus improved or was constant at 19 of 29 streams since 1990 and 23 of 27 streams since 1970-1980. Median 2001–2005 levels were fair to good at 100% of DO stations, 75% for TSS, 48% for bacteria, 60% for TKN, and 43% for phosphorus. Water quality improves with increased forest area in Delaware watersheds. Since the Federal Clean Water Act Amendments of the 1970s, improving water quality stations (50) outnumbered degrading stations (23) along Delaware streams by a 2:1 margin. Since 1990, degrading water quality stations (46) exceeded improving water quality stations (38) indicating a slight reversal from the early gains achieved since the implementation of the 1970s Clean Water Act amendments.
