Hog Island Shore Protection And Habitat Restoration Living Shoreline Project, C. Scott Hardaway Jr., Donna A. Milligan, Christine A. Wilcox, Nicholas J. Dinapoli

Reports

Hog Island is an emergent estuarine marsh complex that is part of the overall Guinea marshes (Figure 1). These marshes are located at the confluence of Mobjack Bay and the York River in Gloucester County, Virginia. Hog Island is a high wave energy eroding shoreline along its south-face on the York River, and lower wave energy along its west and east flanks that occur on Monday Creek (Figure 2). The marsh consists mainly of grasses such as Spartina alterniflora and Spartina patens. A higher, sandy area along the higher energy shorelines has some scrub shrub. Two small ponds and a ...


Farm Resiliency Education For At-Risk Coastal Areas In The Chesapeake Bay, Kristen Saacke Blunk, Kristen Hughes Evans, Jennifer Miller Herzog, Julie Herman, Carl Hershner, Donna Bilkovic, Kirk J. Havens Aug 2020

Farm Resiliency Education For At-Risk Coastal Areas In The Chesapeake Bay, Kristen Saacke Blunk, Kristen Hughes Evans, Jennifer Miller Herzog, Julie Herman, Carl Hershner, Donna Bilkovic, Kirk J. Havens

Reports

The Virginia Institute of Marine Science (VIMS) in collaboration with its partners, the Land Trust Alliance, Sustainable Chesapeake, and The Nature Conservancy, explored and refined questions critical for advising and guiding landowners who farm within coastal areas that are vulnerable to sea level rise and saltwater intrusion, and ultimately, loss of arable cropland in the Chesapeake Bay watershed. While the questions posed are those that agricultural experts across the coastal zones are struggling with, this effort focused on identifying the current state of the science and informational gaps; building current, best professional guidance for landowner conservation program choices; and developing ...


Virginia Game Fish Tagging Program Annual Report 2019, Susanna Musick, Lewis Gillingham May 2020

Virginia Game Fish Tagging Program Annual Report 2019, Susanna Musick, Lewis Gillingham

Reports

Through 2019, the Virginia Game Fish Tagging Program (VGFTP) has maintained a 24-year database of records for tagged and recaptured fish. The program is a cooperative project of the Virginia Saltwater Fishing Tournament (VSFT) under the Virginia Marine Resources Commission-(VMRC) and the Virginia Institute of Marine Science (VIMS) of the College of William and Mary (under the VIMS Marine Advisory Program).

Data

This work complements the efforts by the Virginia Tech Department of Civil & Environmental Engineering in SERDP MR18-1233, as described in the project’s final report (Stark et al, 2020) and in the Master’s thesis by Dennis Kiptoo (Kiptoo, 2020). One of the objectives of the project was to improve calibration of the Bluedrop free fall penetrometer (FFP) with high resolution sampling of a variety of sediment types. To accomplish this, a series of 9 stations over 12 cruises were visited along the York River, an estuary in the Virginia portion of the Chesapeake Bay, and in the Pamunkey River ...

Previous work on this project, conducted in the York River during 2018-2918 worked to improve calibration of the Bluedrop free fall penetrometer (FFP) with high resolution sampling of a variety of sediment types (Massey et al, 2020a). Calibration methods developed (Kiptoo, 2020) were used to rapidly identify different sediment types from a grid of 59 Bluedrop PPF stations sampled on ...


Shoreline Management Handbook, Pamela Mason, Angela King, Clay Bernick Apr 2020

Shoreline Management Handbook, Pamela Mason, Angela King, Clay Bernick

Reports

Shoreline habitats and processes are impacted by the decisions we make about managing coastal development and shorelines. Shoreline Management is making choices to address the desire to protect upland property from erosion or develop property balanced with the benefits and uses of natural and nature-based shoreline features and shoreline habitat restoration. This requires a weighing of the private benefits and cots of management actions and the benefits and costs to public held common resources, also known as the public trust. The natural features along our shorelines -tidal wetlands, beaches and dunes, and riparian buffers, are economically and ecologically valuable. They ...


Surface Water Nitrogen Attenuation From The Accomack County, Va Southern Landfill Groundwater Discharge, Richard A. Snyder, Paige G. Ross Feb 2020

Surface Water Nitrogen Attenuation From The Accomack County, Va Southern Landfill Groundwater Discharge, Richard A. Snyder, Paige G. Ross

Reports

Previous sampling of the stream crossing Bobtown Road (Rt 178) near the intersection of Hollies Church Road (Rt. 620), had indicated high levels of nitrogen in the stream flow (Snyder and Ross, 2019a). The proximity of the retired Accomack County Landfill upstream of the site triggered a higher resolution sampling of the stream in an attempt to isolate a source of the nitrogen loading (Snyder and Ross, 2019b). Accomack County has requested repeated sampling of this stream segment to monitor nutrient attenuation trends from the site, and stations were established for that purpose. This is the first report of that ...


Monitoring The Abundance Of American Shad And River Herring In Virginia's Rivers - 2019 Annual Report, Eric J. Hilton, Robert Latour, Patrick E. Mcgrath, Brian Watkins, Ashleigh Magee Jan 2020

Monitoring The Abundance Of American Shad And River Herring In Virginia's Rivers - 2019 Annual Report, Eric J. Hilton, Robert Latour, Patrick E. Mcgrath, Brian Watkins, Ashleigh Magee

Reports

This report describes the results of the twenty-second year of a continuing study to estimate the relative abundance and assess the status of American shad (Alosa sapidissima) stocks in Virginia by monitoring the spawning runs in the James, York and Rappahannock rivers in spring 2019, evaluating hatchery programs, and contributing to coast-wide assessments (ASMFC 2007). We also report on two fishery-independent monitoring programs using anchor gillnets in the Rappahannock River (year 2) and the Chickahominy River (year 5; a major tributary of the James River), to determine relative abundance and stock structure for the adult spawning run of river herring ...


Water Quality In Accomack County Freshwater Streams, Richard A. Snyder, Paige G. Ross Jan 2020

Water Quality In Accomack County Freshwater Streams, Richard A. Snyder, Paige G. Ross

Reports

Expansion of poultry house operations and use of litter as a soil amendment in Accomack County Virginia has raised concerns for water quality impacts both seaside and bayside of the Eastern Shore of Virginia (ESVA). This ongoing investigation is examining freshwater stream water quality in Accomack Virginia to identify water quality impairments from poultry operation storm water runoff. Sampling in 2019 followed two inch rainfall events covering 83 streams at road crossings in southern and northern Accomack County. Estimates of land cover in the drainages for these streams were used to determine correlations between stream water nutrient levels and the ...


Expanding The Use Of Natural And Nature-Based Infrastructure To Enhance Coastal Resiliency: Forecast And Hind-Cast Load Reductions From Living Shoreline Bmps : Project Report (Year 2 Of 3), Marcia Berman, Pamela Mason, Tamia Rudnicky Jan 2020

Expanding The Use Of Natural And Nature-Based Infrastructure To Enhance Coastal Resiliency: Forecast And Hind-Cast Load Reductions From Living Shoreline Bmps : Project Report (Year 2 Of 3), Marcia Berman, Pamela Mason, Tamia Rudnicky

Reports

The vulnerability of coastal communities and the growing risks to coastal infrastructure continue largely due to past and ongoing patterns of development in high risk areas. This project is focused on increasing the use of natural and nature-based features (NNBFs) to increase resilience of coastal communities to flooding caused by extreme weather events. This project has proposed two efforts to increase understanding of NNBFS; 1) describe the current status, and 2) quantify role of NNBF creation/ restoration for water quality benefits in support of coastal resilience. The products of the 3-year project are intended to support informed coastal management decision-making ...
