Algae Control

The objective is to prevent algae activity, particularly blue-green algae blooms.Techniques include algaecides to kill algae, but also a number of preventive measures to reduce internal and external nutrient loading which causes excessive algae production.

 

Harmful Algae Blooms (HAB)

During the summer of 2017 Swartswood Lake experienced three Harmful Algae Blooms (HAB). Apparently Swartswood Lake experienced the first recorded HAB event in New Jersey, although subsequently HAB’s occurred in at least eight other New Jersey lakes during 2017. HAB’s have only recently been recognized by the industry as potentially harmful toxic events. As a result information and decisions on how to deal with HAB’s is evolving. The focus of the presentation is to inform the NJCOLA community on the Swartswood Lake experience, provide examples of what HAB’s might look like, identify the potential risk to humans and identify steps lake communities can prepare so that they can more rapidly respond to an HAB should it occur.

The information contained in the presentation below is based upon publications and web information by the World Health Organization, United States Environmental Protection Agency, New York State Department of Environmental Conservation and New Jersey Department of Environmental Protection (NJDEP). Website relied upon for the presentation are identified in the slides. Also NJDEP and Swartswood Lakes and Watershed Association met on Thursday September 14, 2017, which is factored into the presentation. It should be noted additional HAB information is contained in presentation materials by Fred Lubnow of Princeton Hydro.
