McPherson (410) 238-4255 (410) 238-4210 Below Normal Rainfall and Warm Temperatures Lead to Record Low Water Levels in December Three months of above normal temperatures and four months of below normal rainfall have led to record low monthly streamflow and ground-water levels, according to hydrologists at the U.S. Geological Survey (USGS) in Baltimore, Maryland. Streamflow was below normal at 94 percent of the real-time USGS gaging stations and 83 percent of the USGS observation wells across Maryland and Delaware in December. Record low streamflow levels for December were set at Winters Run and Pocomoke River. Streamflow levels at Deer Creek and Winters Run in Harford County have frequently set new record daily lows for the last four months (see real-time graphs at http://md.water.usgs.gov/realtime/). Streamflow was also significantly below normal at Antietam Creek, Choptank River, Conococheague Creek, Nassawango Creek, Patapsco River, Gunpowder River, Patuxent River, Piscataway Creek, Monocacy River, and Potomac River in Maryland, and Christina River, St. Jones River, and White Clay Creek in Delaware. The monthly streamflow in the Potomac River near Washington, D.C. was 82 percent below normal in December and 54 percent below normal for 2001. Streamflow entering the Chesapeake Bay averaged 23.7 bgd (billion gallons per day), which is 54 percent below the long-term average for December. -

Delaware Offshore Geologic Inventory 2001 to 2008
Executive Summary Episodic large storms and trends in long-term shoreline change continue to erode Delaware's beaches. To combat the erosion, beach nourishment is the preferred method for maintaining the Atlantic shoreline of Delaware for the purpose of protecting structures and infrastructure. State, local, and federal governments have contributed to the protection against coastal erosion. There were a number of government-sponsored beach fills between 1957 and 2005, and those amounted to emplacing 9,491,799 cubic yards at a cost of $23,960,001 (DNREC, 2005 spreadsheet). Most of the sand used for these projects came from upland sites and several areas offshore Delaware. As those sites become depleted, new sources of sand must be found. Over the past 18 years, the Delaware Geological Survey (DGS) has compiled a geologic database titled the Delaware Offshore Geologic Inventory (DOGI). This database contains information on the location of potential sand resources from state and federal waters for use in beach nourishment. The DGS has worked in partnership with the US Minerals Management Service (MMS) and the Delaware Department of Natural Resources and Environmental Control (DNREC) to determine the offshore geologic framework and to identify new sources of beach- quality sand. Also included in the DOGI are vibracores (cores) that were taken from offshore Delaware. The DGS maintains the state’s offshore core repository. This report represents a compilation of data that has been collected for the DOGI from 2001 to 2007 in partnership with MMS. During this time period, a total of 61 cores were collected in the Atlantic waters offshore Delaware for the purpose of determining potential borrow areas that could be used for beach nourishment. -

Karen Bennett, Greg Moore and Janet Dennis of the Delaware Division of Fish and Wildlife Bill McAvoy of the Delaware Natural Heritage Program Dr. John Kartesz of the Biota of North America Program Dr. Keith Clancy and Pete Bowman, Ecologists, formerly of the Delaware Natural Heritage Program Ery Largay and Leslie Sneddon of Natureserve All people unmentioned who made countless contributions to this document. -Take me to the vegetation community keys- Guide to Delaware Vegetation Communities-Spring 2009 Introduction The Guide to Delaware Vegetation Communities is intended to provide a Delaware flavor to the National Vegetation Classification System (NVCS). All common names of communities, except for those not in the NVCS, follow the NVCS. This document is designed for the web and CD only, but desired sections can be printed by users. In this matter, paper and therefore trees can be preserved and impacts to the communities discussed within can be minimized. In spirit of saving these communities please only print those community descriptions that you will use or print none at all. The State of Delaware covers 1,524,863.4 acres of which 1,231,393.6 acres are terrestrial and 293,469.8 acres are water (Table 1). Currently 130 vegetation communities are known to occur in Delaware. Some of the largest vegetation communities/land covers in the state include: Table 1. -
