THE PRESENT AND POTENTIAL PRODUCTIVITY OF THE BAYLOR GROUNDS IN VIRGINIA.

By Dexter S. Haven, James P. Whitcomb and Paul c. Kendall Special Report Noa 243 in Applied Marine Science and Ocean Engineering Virginia Institute of Marine Science and School of Marine Science, The College of William and Mary Gloucester Point, Virginia 23062 April, 1981 FOREWORD Introduction This is Volume II of a study of the Baylor Grounds in Virginia. The study is presented in two volumes: Volume I. The foreword and discussion of the Baylor Grounds in the following river systems: The Rappahannock, Corrotoman, Great Wicomico, Piankatank, York and Poquoson rivers, and Mobjack Bay and its tributaries (East, North, Severn, and Ware rivers). Volume II. The Baylor Grounds in the James River, Pocomoke and Tangier sounds, the Bayside and Seaside of the Eastern Shore, and the Virginia tributaries of the Potomac River (Coan and Yeocomico rivers, and Lower Machodoc and Nomini creeks}. Volume II also contains charts of all the Baylor Grounds discussed in Volumes I and II reduced to page size from 1/10,000 charts. Volume II represents our final report on the project (Contract No. 3-265-R-3). Large scale 1/10,000 charts were prepared for this report showing bottom type on the various Baylor bottoms. These master charts are on file at the Institutei copies at 1/20,000 scale may be obtained on request at cost from the Institute. We have submitted to the Virginia Marine Resources Commission along with Volume II, copies of the 1/10, 000 charts at 1/20,000 scale. Copies of these charts may also be obtained at cost £rem the Institute upon request. i Funding This study was funded as a matchi~g fund_ grant with funds provided by the Nati.anal Marine Fisheries Service thro~gh the Virginia Marine ·Resources Commission (Contract No. 3-265-R-3). We gratefully acknowledge the role of Conunissioner James E. Douglas, Jr. and members of the Vi~ginia Marine Resources Commission for providi~g matching funds to the Institute for this study. We also extend our thanks to the many employees of the Commission who assisted us. The services of Reinaldo Morales-Alamo of the Institute's staff as well as others who crewed the survey are also gratefully acknowledged. We are especially thankful for the services of Mrs. Gloria Rowe who typed this report. Purpose of the Study and Its Objectives There has long been a need by management agencies to know more about the state's public oyster bottoms in respect to their value or suitability for shellfish culture. The study of 1894 referred to as the Baylor Survey only delineated the bounds of the naturally productive oyster beds. It did not include an examination of the bottom; no biological data were considered. The original 1894 study delineated 210,074 acres and it included much of Virginia's naturally productive bottom. It also included, however, much barren or unproductive bottom (Moore, 1910). Since the original study 32·,274 acres were added by petition or by legislative action (Haven, Hargis and Kendall, 1978). Today, the Baylor bottoms occupy most of the area in many of Virginia's estuaries (Figure 1). ii ""~ ~ ""Q... ~ (/) ...i -.,,,....-:-::-ff.a_,..:.._...,......l~-- - ---------, ~ --:-----~~~F".'"-:-''----:4~R----------~40' ~ ~ , ..j ~ ]30'~ i ~ -~t H~ -~ 1 ~10 -1 ~ i --+------------_;Jwoo'~ST• I! ~ ~ . ~IIO' ~ H Figure 1.
