Lake Preservation Tips and Info
Spring 2018 President's Report - Art Wood
The ALMA organization has been busy throughout the fall and winter making sure that the lake will remain the wonderful asset that we have all come to love. Here are Some of the activities that have gone on throughout the fall and winter to keep our lake healthy.
Water quality is always of importance when it comes to maintaining the quality of the lake. While water monitoring ends in October due to lake levels and Ice the summer data was analyzed by our limnologist George Knocklein. Fortunately, although some levels did creep up to a marginally unacceptable level by October George says that he does not see any issues with Andover Lakes water. His recommendations are to continue to monitor water quality and weed population, but no other actions are required right now. We will be lowering the level slightly in the next few weeks to allow a more comprehensive perimeter sampling. This study collects and tests samples of water entering the lake from 26 locations for bacteria and other chemicals (nutrients) which might suggest problems with septic systems. This should be completed by the third weekend in March, provided there is no ice remaining on the lake, it will then be brought up to the summer level.
Weeds are also a concern with lakes like ours however George also sees no problem with our lake in that area.
Maintenance on the Dam walkway was also done in the late fall by ALMA. The boards on the walkway were treated with a preservative and the bolts holding the boards on were tightened or replaced where necessary. There are a few boards that have warped or cracked, and these will be replaced in the spring. An additional boat rack was also added to the 320 Lake Road Right of way.
Several residents have applied for approval to perform maintenance on the waterfront or build retaining walls. ALMA has reviewed these applications and worked with the land owners to find acceptable solutions.
On the administrative side ALMA has elected officers for 2018, click on Contact Info tab to view.
Retaining Walls & Docks
ALMA must approve all docks, floats and walls constructed or placed on the Lake. This applies to new docks, floats, and walls, as well as to changes to existing docks, floats, and walls beyond simple maintenance. A written description of the project must be submitted to ALMA. The DFW committee will review these proposals. Before erecting a dock or float or building a wall - please read the Wall Guidelines and Wall Application AND Dock Guidelines and Dock Application or Pulling weeds consent must first be obtained from ALMA.

How you can help to keep the lake clean
>Pick up your dog’s droppings from all paths, right-of-ways, dam area and roadways.
> Phosphates are a major source of algae blooms, weed growth, and poor water quality in lakes. ALMA and ALPOA discourage the use of any lawn fertilizer, but if you must, use one without phosphates. New state laws restrict the use of fertilizers with phosphates. Use phosphate-free detergents.
> Landscaping does affect the flow of nutrients into the lake. A buffer zone of native vegetation along the shore and rain gardens to collect runoff are proven to reduce the flow of nutrients into the lake. A rain garden is a planted depression or a hole that absorbs rainwater runoff from impervious areas, like roofs, driveways, and walkways. Often it is an area that has been excavated, filled with sand, and planted with native shrubs.
> Pump your septic tank and have it inspected on a regular basis – every three years is recommended.
As owner of the lake and right of ways ALMA makes every effort to protect the lake environment and keep the lake clean and healthy. Here are a few things that you can do to help preserve the lake:
Eliminate the use of fertilizer especially Organic fertilizer
Keep your Septic system well maintained and pump it every three years
Remove any organic matter from the lake such as leaves or grass clippings
Even if you don’t live on the waterfront this will help protect our beautiful lake.
Sediment Report: Click on Sediment Report to read the final report that describes investigations on the nature of sediments in the south Bay (aka the “cove”) of Andover Lake by Drew Hyatt and his students from Eastern Connecticut State University (Department of Environmental Earth Science).
This report describes findings based on (a) probing the thickness of sediments in the bay, (b) recovering and analysing sediment cores from the bay, (d) determining the age of sediments, and (d) collecting ground penetrating radar to map sediment thickness and water depths throughout the bay. Key findings and implications for potential dredging are summarized on pages 328-31.”
