Pachaug Pond is a shallow lake with 10 coves.  Since light penetrates to the bottom of the lake, it is especially susceptible to the growth of aquatic invasive species.  The lake is currently plagued by overgrowth of 

fanwort, variable-leaved milfoil, Eurasian milfoil, and minor naiad.  Past winter drawdowns of the lake level have not proved effective in controlling weed growth since these plants are located at depths which are unaffected by drawdowns.  The lake's sheltered coves are especially immune to the effects of the drawdowns.  The most recent survey of the lake concluded that additional actions must be pursued the control the lake's invasive species.


It is the charge of the PPWCA to develop a long-range management plan prioritizing treatment areas within the pond, set up a schedule for using alternate methods at each of the prioritized areas, track success of drawdowns and any alternate methods used to control invasive aquatic plants, and annually review the management plan.

Solutions will be reviewed with a focus on minimizing cost, maximizing weed control and meeting the criteria for state approval.  Our first strategy will be the use of a mechanical weed harvester to pull weeds by their roots from the pond.  Other possible future strategies include introduction of aquatic herbicides, introduction of sterile weed-eating carp, the use of ultraviolet lights, and implementation of annual managed drawdowns of the lake.


​PPWCA has completed the following steps to initiate coordinated preservation efforts:

  • Established Pachaug Pond Weed Control Association

  • Named Board Members and elected officers

  • Developed and approved a Mission Statement

  • Developed and approved By-Laws

  • Determined a process for membership in PPWCA

  • Established a sub-committee to research use of sterile carp for weed control

  • Designed and published a website

  • Created an e-mail account 

  • Established a non-profit organization with 501c3 status

  • Held two annual Golf Tournament fundraisers

  • Selected and hired a firm which has completed 2 annual surveys of weeds and water quality of Pachaug Pond in 2017 and 2018

  • Held two neighborhood-wide yard sales

  • Completed drone surveys and weed survey

  • Held our first annual Comedy Night Fund-Raiser

  • Unanimously approved use of a mechanical weed harvester as our Phase 1 weed control strategy

  • Launched a fund-raising campaign to raise funds for an ECO Mechanical Weed Havester

  • Applied for and received grant funding


The following activities are currently underway to deepen and extend our preservation efforts:

  • Engage a variety of stakeholders and increase membership

  • Pursue annual managed drawdowns of the lake

  • Explore a variety of funding sources and apply for grant funding

PPWCA plans to pursue the following activites in the future:

  • Promote education of all stakeholders

  • Select a multi-facetted solution and submit related requests for permits to the state

  • Implement weed control strategies

  • Develop a longterm plan for continued weed control

Most weed control strategies require permits, either from the local wetlands commission or from the DEEP.  PPWCA is committed to following the state and local regulatory processes to ensure any weed control methods implemented receive required approvals. Recommendations or ideas discussed at meetings are representative of individual opinions and are not necessarily those of the PPWCA.
