Cranstons Mill Pond Nutrient Bank

Cranstons Mill Pond


 IN 2009 CBNLT teamed up with Restoration Systems of North Carolina on a project to be known as Cranstons Mill Pond. The property is located on the east side of State Route 632 (Cranston’s Mill Pond Road) in James City County, approximately 4 miles southwest of Toano. The pond is historically an impounded segment of the Yarmouth Creek, which drains to the Chickahominy River at Wrights Island and then to the James River and into the Chesapeake Bay.

Property Description:

The property is approximately 50+ Acres of Pond with 5 Acres of upland areas. The historic mill pond dominating the parcel had been in place for approximately 100 years.The earthen dam was breached during Hurricane Ernesto on September 1, 2006, causing lowered water elevation in the pond and allowing nutrients to flow downstream into the Chickahominy River, the James River, and ultimately the Chesapeake Bay.

Watershed Conditions

In 2003 the DCR conducted a natural resource inventory and classified portions of the sixteen square mile watershed as highly significant to biodiversity in the state. This resource inventory would become to be known as the Yarmouth Creek Watershed Plan. The Yarmouth Plan states that the watershed contains extensive complexes of nontidal wetlands, forested uplands, bald cypress swamps, and rare types of tidal freshwater marsh. Many of these highly functional and environmentally sensitive communities are located in the tidal mainstem of Yarmouth Creek downstream from Cranston’s Mill Pond, emphasizing the importance of maintaining the historic pond and preventing nutrients and sediments from polluting well established ecosystems. The Yarmouth Creek watershed provides a high level of recreational value due to the diversity of fish, waterfowl and wildlife.

Project Goals and Objectives:

The primary goal of the project is the reduction of nitrogen and phosphorus loading nto the Chesapeake Bay and its tributaries (specifically Yarmouth Creek, the Chickahominy River and the James River). These reductions will Provide DEQ and the Department of Conservation and Recreation (“DCR”) with an implemented project in the Bay watershed that provides innovative, demonstrable, and quantifiable progress towards Virginia’s commitment to nutrient reduction and meeting the Bay TMDL (total maximum daily loading) goals as established in coordination with EPA.

Secondary Goals are to restore the hydrologic conditions above Cranston’s Mill Pond dam and eliminate the ongoing head-cut erosion of the pond-bed sediments. Once these items are addressed we can prevent further degradation to the water quality downstream of Cranston’s Mill Pond ncluding reaches of Yarmouth Creek, the Chickahominy River, the James River, the Chesapeake Bay and associated high quality tidal and nontidal wetlands. Additional ancillary benefits may include reducing the potential for a) stream bed and bank erosion; b) loss of established habitats within and downstream of the Property; c) changes to riparian vegetation; d) increase in invasive species, and e) increased flooding of and damage to state roads.
