2009 Sediment Study by Christopher Newport University (PDF - 1.8MB) - Study to "observe the potential impacts of weather on the physical conditions of Lake Tecumseh in Virginia Beach, with specific emphasis on turbidity outflow". Study discusses Lake Tecumseh as a sediment source instead of a sediment sink and the impact of this on environmental conditions in the lake. In September 2009, the second phase of this study was initiated by Christopher Newport University Center for Wetland Conservation. This portion of the study seeks to further quantify the contribution of suspended sediment from Lake Tecumseh to the Back Bay Estuary and how it compares to other sources such as Muddy and Nawney Creeks.
2009 Navigability Determination by the Army Corps of Engineers (PDF) - Army Corps of Engineers letter that states that Lake Tecumseh will remain a navigable water of the United States after installation of the weir.
2005 Recreational Use Survey (PDF) - Prepared by Old Dominion University. The purpose of the study was to document the extent and type of uses that occur in Asheville Birdge Canal.
2004 Flood Study (PDF - 743KB) - The report titled "Simulated Flooding Effects of Proposed Water-Control Structures for Lake Tecumseh and Adjacent Wetlands in Virginia Beach, Virginia" was published in 2004 by Jefferson N. Keaton of the United States Geological Survey. The U.S. Fish and Wildlife Service had received a grant for the restoration of Lake Tecumseh. Two management strategies were established for the restoration, including installing flap gates on Canal 1 to prevent wind-driven tides form entering Lake Tecumseh or installing a weir across the outlet of Canal 1 that connects to the lake. This report evaluates the hydrological effects on upstream water levels of the two alternatives of the mangement plan for Lake Tecumseh and adjacent wetlands in Virginia Beach, Virginia. Please be aware this study includes an analysis of a weir placed either in Asheville Bridge Canal or Lake Tecumseh. A weir in Asheville Bridge Canal was included in this study because at the time the City of Virginia Beach was looking for solutions to flooding issues in the communities of Red Mill and Ocean Lakes. The weir in Asheville Bridge Canal was included to determine if excluding wind tide flooding in the canal north of the proposed Nimmo Parkway alignment would eliminate the flooding problems in these neighborhoods. The U.S. Fish and Wildlife Service does not support placing a weir in Asheville Bridge Canal. This would violate the established goals and accomplishments of the Lake Tecumseh weir project. The City of Virginia Beach contracted with URS Corporation in 2007 to perform an additional flood study to determine the effect of the weirs on surrounding communities. The results were identical to the study performed by USGS in 2004. Copies of the study may be obtained from the City of Virginia Beach Stormwater Management Department at the address below.

2000 Effect of Sediment on Aquatic Life (PDF - 938KB) - An article that describes the imapct that sedimentation can have on aquatic life.
1967 Engineering Study (PDF - 1.4MB) - Report completed by Langley, McDonald, and Overman for the City of Virginia Beach to study the possible effects of the construction of a waterway connecting Back Bay with the Atlantic Ocean through Rudee Inlet.
1958 Hydrological Report (PDF - 3.8MB) - The report was submitted in August 1958 by the Bureau of Sport Fisheries and Wildlife of the Fish and Wildlife Service, United States Department of the Interior. It discusses the probable effects on fish and wildlife resources of the watershed as a result of the proposed Princess Anne County Watershed project. The watershed is composed of the drainages of several streams that originate in Princess Anne County which empty into North Landing River or Back Bay.The objective of the project was to obtain better drainage of farm land in the watershed through the construction of several new drainage ditches. Fish and wildlife resources of both the project area and Currituck Sound were included in the assessment. The report suggests alternatives to minimize adverse effects on fish and wildlife resources.
