NEW! Mirror Lake Phase 2 Analysis Sampling Report Summary

This report evaluates the chemical and physical characteristics of sediment samples from Mirror Lake to support a 401 Water Quality Certification application for a proposed restoration and dredging project. The analytical testing determined that the lake's sediments are clean and free of significant contamination, meaning the material may be eligible for upland reuse as the project moves forward into engineering and permitting phases.

  

Key Details

  • Project Purpose and Background: TRC Engineers, LLC assessed Mirror Lake to support the submission of a 401 Water Quality Certification to the MassDEP, which aims to reduce the impacts of eutrophication and maximize the lake's long-term recreational potential through dredging.


  • Sampling and Laboratory Testing: Adhering to an approved sampling plan, 21 distinct      composite sediment samples were collected from 58 core locations and analyzed by a certified laboratory for physical properties, grain size, and various chemical analytes including select metals, PAHs, PCBs, EPH, and VOCs


  • Results and Next Steps: Laboratory results showed that no detected analytes exceeded MassDEP thresholds, indicating the sediment is clean and suitable for potential upland reuse. Recommended next steps for the project include consulting with dredge contractors, evaluating upland reuse parcels, holding a kick-off meeting with MassDEP, and developing an engineering design for formal permit submission.

Lake Management

Our lake is under constant threat

 Like all bodies of water, Mirror Lake is a fragile ecosystem whose continuing existence and healthy longevity is up to us…all of us! 


Without continuous intervention, focus and resources, our lake will die by transitioning to a swampy wetland.

Your community in action for the benefit of the lake

Friends of Mirror Lake (FOML) formed in 2017 as a volunteer community organization by concerned residents of Wrentham and Norfolk who live on and around the lake. We make it our mission to preserve and restore our fantastic lake, while driving an active, responsible, and caring neighborhood community that will benefit all generations. Learn more in this short video.

 

Leveraging accredited scientific research analysis and accepted remediation practices (in accordance with federal, state, and municipal laws), we seek to improve the water quality and health of the lake for the equal benefit of wildlife, fisheries, and humans. We aim to improve and sustain the lake's health to ensure it remains habitable for animals and humans. We also partner closely with Wrentham and Norfolk town officials, while also promoting a tight-knit lake community that bonds and collectively enjoys our fantastic natural resource.

Since its formation, Friends of Mirror Lake has:

  • Worked closely with the towns of Wrentham and Norfolk to obtain permits and funding to annually treat invasive and non-invasive aquatic plants, including: curly leaf pond weed, lilly pads and bladderwort 
  • Successfully lobbied for Town funding for critical lake studies and infrastructure projects
  • Driven neighborhood and lake clean-up efforts
  • Developed and posted content around the lake and on our social feeds to help educate residents and visitors about how to be lake stewards 
  • Organized educational events for residents and government officials
  • Formed stronger partnerships with neighboring Lake Archer and Lake Pearl volunteer organizations
  • Attended and presented at town meetings about our lake
  • Organized and conducted water health tests with licensed organizations.
  • Formed and expanded a thriving social media community
  • Identified potential sources of funding for longer-term lake improvement efforts
  • Created, promoted and hosted social events throughout the year 

How you can help sustain our lake:

  • Self-educate on lake issues and management:
