Lake Management Home

Lake Management is the term the WLA uses to include lake and stream monitoring, invasive weed management, runoff control, and lake studies.

Lake and Stream Monitoring

The WLA has supported ongoing monitoring of both Webster Lake and the streams in the lake watershed. This monitoring has involved the regular collection of chemical and physical values such as water temperature, clarity, and oxygen content. This is done by volunteer WLA teams in conjunction with consulting firms. Monitoring was originally done by the WLA team on a monthly basis, and is now carried out three times a year: spring, summer and fall.

Weed Management

By far, the largest portion of the WLA budget is used for management and control of invasive weeds. For a variety of reasons, application of herbicides has been found to be the most effective method for control of weeds in the lake and the is method most frequently used by the WLA. Other methods have been considered and recommended in specific situations but have been generally rejected for this lake.

The WLA has employed two different companies (Geosyntec and Aquatic Control Technologies (ACT)) for advice about the type, location, and amount of weed management. Geosyntec was hired to do evaluations of the situation on our lake. ACT was then hired to carry out the weed management program (including obtaining and applying the herbicides) and to help with questions that the WLA might have. ACT is a Massachusetts based licensed company. ACT applies for and works under a permit from the Webster Conservation Board.

The WLA also hired a consultant, Dr. Ken Wagner of Water Resources Services, LLC, to develop a State of the Lake report, completed in 2011. He analyzed a variety of data sources and reported on the effectiveness of the lake management programs of the WLA and on the overall state of the lake. This report was funded wholly by the Janet Malser Humanities Trust.
In 2012, Dr. Wagner conducted a Plant Survey and completed a report which presented and analyzed the results of this survey. This survey and report were funded in part by the Janet Malser Humanities Trust and also by funding from the Webster Lake Association.

The lake management program has generally been successful. It has slowed the spread of the invasive weed species and has reduced the areas of infestation. The complete elimination of these species would be very difficult could not be done without a great amount of work and money. Elimination of these species is not a goal of the WLA weed management program.

Runoff Control

In the past, with the help of money from the state and services from the town, the WLA has been involved in a variety of active steps to help reduce the negative effects of runoff into our lake. Rainwater which drains directly into the lake can carry both silt and pollutants which are damaging to water quality and habitats.

CME Associates, a engineering consultant to the town of Webster, studied the ways in which runoff enters the lake and developed a master plan to correct the main problem areas. Ten to twelve sites were originally proposed where catch basins could be used to reduce the negative effects of runoff. Work at three of those sites was completed, but the others were put on hold. These catch basins trap harmful material before it runs into the lake. The WLA has also taken some initial steps to reduce the flow of damaging pollutants from lawn fertilizers and other treatments. More work needs to be done in all of these areas.
