BOROUGH OF MOUNTAIN LAKES
Morris County, New Jersey
Mr. Gary Webb, Borough Manager

STATUS – 1990 – present

Manage the community lakes to maximize recreational use, to improve the ecological community of each lake and to protect the Borough’s property values.

PROJECT STATEMENT - MANAGEMENT OF 9 BOROUGH-OWNED LAKES

Allied Biological has been the Borough’s Lake Management Consultant for more than a decade. In the early 1990’s, the Borough largest lakes suffered from recurring phytoplankton blooms, which rendered the lake unusable in the hottest part of the summer. Allied Biological initiated a restoration project centered on the use of aluminum sulfate to sequester in-lake nutrients and prevent them from fueling phytoplankton growth. Alum applications resulted in steep declines in phytoplankton populations and enormous water clarity improvements, effectively restoring the lakes to a balanced plant-algae community.

Allied Biological has continued to employ alum sensitively throughout the last decade, in combination with selective aquatic plant management and water quality assessment. The Borough has also conducted a multi-year Lakes Cleaning Project employing Allied Biological’s hydro-rake services to remove accumulations of leaves and other organic debris in portions of each lake. Allied Biological meets with the Lake Committee each month to review activities and consult on lake issues.

GLEN LAKE PROTECTIVE ASSOCIATION
Queensbury, New York
Paul Derby, President

STATUS – 2004 – present

Prepare an Aquatic Vegetation Management Plan and conduct selective management of native and invasive aquatic plants.

PROJECT STATEMENT

In Spring, 2004, Allied Biological was awarded a contract by the Glen Lake Protective Association (GLPA) to develop an Aquatic Vegetation Management Plan for their 320 acre lake. The focus of the Plan was to be the assessment and management of the invasive aquatic plant Eurasian Watermilfoil, which threatened the lake’s biodiversity and aspects of its recreational use.

Allied Biological completed a review of historical data and conducted mapping of lake vegetation and water quality assessment in preparation of the Plan. The Plan was then presented to the GLPA at a regular meeting in the winter of 2004-2005, and ultimately accepted. The Plan was submitted to the NY Department of Environmental Conservation in early 2005 in conjunction with a permit application to apply aquatic herbicides in portions of Glen Lake.

Allied Biological conducted the herbicide application in Spring 2005. Control of the target plants was successful, and lasted through the early summer of 2006, two to three months longer than anticipated. The GLPA retained Allied Biological to make adaptations to the Plan based on the applications results and then repeat the detailed plant mapping in Summer, 2007 in anticipation of a permit submission for an alternative plant control in 2008.

BRISTOL-MYERS SQUIBB HEADQUARTERS LAKE
Lawrenceville, New Jersey
Ronald Kadi, Project Engineer

STATUS – 1995 – present

Manage the lake as an aesthetic focal point of the campus, and ensure NJPDES compliance.

PROJECT STATEMENT

Prior to 2000, Allied Biological conducted a biological enhancement program at the BM Squibb Lawrenceville lake. The program was designed to sequester nutrients in beneficial bacteria, thus reducing algae growth. This proved insufficient to reach project goals and a comprehensive Action Plan for the lake was adopted in November, 2001.

The Action Plan detailed a multi-faceted approach to restoration of the lake, emphasizing reduction of manageable nutrient sources. To minimize recycling of in-lake nutrients, Allied Biological installed a diffused air injection system and continued biological enhancements. Bristol-Myers Squibb aided the program by aggressively managing geese populations and adapting landscaping programs to reduce runoff. Over a period of three years, Allied Biological also installed native emergent plants along the entire lake shoreline. These plants provided for nutrient uptake, filtration of runoff and improved habitat for aquatic organisms.

Allied Biological continues to maintain the lake and provide on-going water quality assessment. Since the Action Plan was initiated, water quality has been vastly improved and the lake has returned to a more balanced ecological community without significant algal blooms.
