This summary report is part of a series documenting the field site investigations conducted by the Habitat Development Project initiated to study for more definitive information on the environmental impact of dredging and dredged material disposal operations. This report documents tasks such as: (a) Effects of Marsh and Terrestrial Disposal, (b) Marsh Development, (c) Terrestrial Habitat Development, (d) Aquatic Habitat Development, and (e) Island Habitat Development.

This report follows the Windmill Point marsh habitat development project. The marsh was constructed in the James River between November 1974 and February 1975, then studied for benthic invertebrates, fish, wildlife, plants and soil characteristics from the summer of 1976 to fall of 1977.

From preface: "This report contains the results of investigations of the chemical and sedimentological characteristics of the James River Artificial Habitat Development Site and a reference marsh near Windmill Point, Virginia. Studies were conducted in the channel before dredging and during site construction as well as at specific time intervals after marsh development."

Appendix containing sediment parameters from macrobenthic sampling locations to accompany a report on the environmental impacts of marsh development with dredged material as part of a study on the feasibility of marsh development using dredged material at the Windmill Point Marsh Development Site, James River, Virginia.

Appendix containing supplementary tabulated data to accompany a report on habitat development field investigations of the Windmill Point Marsh Development Site, James River, Virginia.

Appendix containing an assessment of vegetation on a dredged material island located near Windmill Point in the freshwater tidal reach of the James River. It accompanies a report on habitat development field investigations of the Windmill Point Marsh Development Site, James River, Virginia.
