Authors: Butler, Afrachanna D.; Thomas, Catherine C.; Calomeni, Alyssa J.; McQueen, Andrew D.; Slack, William Todd
Abstract: The proliferation and shoreline accumulation of the filamentous biphasic cyanobacterium, Microseira wollei (M. wollei) (previously classified as Lyngbya wollei), have become an increasing problem in the Great Lakes, both for aesthetic reasons and its potential to harbor harmful bacteria and pathogens (Vijayavel et al. 2013). Occurrences have been reported and studies have also been conducted in the southeastern US where M. wollei has become a nuisance in recent years and is known to produce toxins (Hudon et al. 2014). Reports of M. wollei proliferations in the eastern US have been identified in the Manitoba lakes (Macbeth 2004), in Lake Erie from Maumee Bay (Bridgeman and Penamon 2010), in Lake St. Clair near Detroit (Vijayavel et al. 2013), and throughout the St Lawrence River (Vis et al. 2008; Lévesque et al. 2012). M. wollei has become a serious nuisance for marinas, public beaches, and lakefront property owners. In addition, M. wollei appears to have the ability to produce a wide range of toxins, but the conditions promoting their production, type, and concentration are poorly known (Hudon et al. 2014). Occurrences of large algal mats matching characteristics of M. wollei have been observed along the northwest shore and nearshore waters of the beach at Lake St. Clair dating back to 2010. To date, a comprehensive study detailing the potential impacts M. wollei has on freshwater ecosystems in the Great Lakes River, particularly Lake St. Clair is lacking. Further, management solutions are not well understood. This technical note (TN) reviews the potential causes of M. wollei blooms and their ecological impacts on aquatic systems and assesses the management options available to eliminate or minimize the impacts of these blooms.

Authors: McKay, S. Kyle; Rupp, Byron R.
Abstract: The US Army Corps of Engineers (USACE), New England District (NAE) conducted a watershed study of the Pamet River basin in Truro, Massachusetts. The study broadly focused on basin planning with specific goals of establishing baseline hydrologic and ecological condition, identifying management opportunities, assessing the relative effects of management opportunities, and recommending alternative courses of action for the community. This technical note (TN) reviews a rapid reconnaissance effort to guide scoping for the broader watershed study related to problem identification, objective setting, management alternatives, and a potential decision framework.

Authors: Medina, Victor F.; Killgore, K. Jack; Hoover, Jan Jeffrey, 1954-
Abstract: The purpose of this report is to review the concept of developing a special channel near the Chicago Area Waterway System (CAWS) to treat ship and barge traffic headed towards Lake Michigan with chlorinated water, minimizing the movement of aquatic invasive species (AIS) into the Great Lakes. This concept was proposed in a white paper titled Conceptual Aquatic Invasive Species Treatment System for the Chicago Area Waterways, which was prepared by CH2M for the Nature Conservancy (CH2M 2016). Victor Medina is an environmental engineer with a strong background in water treatment including disinfection, Jack Killgore and Jan Jeffrey Hoover are research fishery biologists who are experts in AIS, particularly the Asian Carp. All are members of the Environmental Laboratory (EL) of the U.S. Army Engineer Research and Development Center (ERDC). This project identifies several critical concerns that should be considered before pursuing such a course. All issues could be conceivably addressed with additional studies and/or extensive engineering. That said, some of the identified issues may be challenging to overcome.2018-01-01T00:00:00ZRiparian buffers for runoff control and sensitive species habitat on U.S. Army Corps of Engineers lake and reservoir projectsMedina, Victor F.Fischer, Richard A., Jr., 1964-Ruiz, Carlos E.https://hdl.handle.net/11681/203652023-04-06T18:35:06Z2016-10-01T00:00:00ZTitle: Riparian buffers for runoff control and sensitive species habitat on U.S. Army Corps of Engineers lake and reservoir projects
Authors: Medina, Victor F.; Fischer, Richard A., Jr., 1964-; Ruiz, Carlos E.
Abstract: Purpose: The purpose of this document is to provide a conceptual framework for a field demonstration of multi-functional, vegetated riparian buffers, which would be placed on reservoir shorelines and riverine tributaries to lakes and reservoirs operated by the United States (U.S.) Army Corps of Engineers (USACE). Riparian buffers will not only provide traditional control of sediment, nutrients, and other chemicals in runoff entering the reservoir, but also potentially provide habitat for federally listed and “at-risk” birds and other sensitive species. The study focuses on applications in the southwestern U.S., which is managed by the USACE South Pacific Division (SPD).2016-10-01T00:00:00Z
