NRWA Vision


A healthy, clean river and corridors of connected wildlife that support the needs of the watershed communities in balance with the needs of fish and wildlife.

NRWA Mission

To protect and restore water quality and fish and wildlife habitats in the The Norwalk River Watershed.



Incorporated in 1996, NRWA is a nonprofit membership organization that accomplishes its mission by engaging community volunteers to help restore native trees, shrubs, wildflowers and grasses to the riverbanks, meadows, parks, and forests of the watershed; working to expand community access to the river, the surrounding open space, and its trails; supporting research and legislative policy that protects biodiversity, clean air, and water; and promoting education, cooperation, and action on the part of the stakeholders in the seven watershed towns in CT (Ridgefield, Redding, Wilton, New Canaan, Weston, and Norwalk) and NY (Lewisboro).


We are working to help implement the Norwalk River Watershed Action Plan.

Project Updates 

  • Partnering with Land Trusts and Municipalities to Plant Trees and Shrubs. In Redding, New Canaan, Lewisboro, Ridgefield, Wilton, and Norwalk (and Darien next door) we helped plant native trees and shrubs along hiking trails and in parks and open space—Weston is set to join that list in 2022. We planted 9 acres of vegetated buffer along rivers, streams, and wetlands this year and are poised to maintain those areas and increase total acreage in 2022.
  • Hosting River & Harbor Cleanups. In April and September 2022, we plan to keep the focus on cleaning up the bend in the river along the Harbor Loop trail in Norwalk. Last year we pulled out 6320 pounds of trash from that spot. 
  • Fighting the impacts of development, dams and dewatering that are threatening Comstock Brook in Wilton. Help us continue the fight to protect Comstock Brook, another Norwalk River tributary and one of the last best places for native brook trout in our watershed. We’re waging this battle through action and education. We invite you to learn more by viewing our on-going Comstock Brook webinar series at norwalkriver.org. You can also help by conserving water, avoiding lawn pesticides, and spreading the word to your friends and neighbors.  
  • Building the Pollinator Pathway. NRWA helped create the Pollinator Pathway in 2017 in Wilton and very soon Ridgefield, Norwalk, New Canaan, Weston, Redding, and Lewisboro NY, all the Watershed towns. NRWA served as the fiscal sponsor for the Pollinator Pathway until 2021 when it became an independent non-profit organization. We are proud to announce that it now connects close to 300 towns! The simple message: plant natives, avoid pesticides, and rethink your lawn is really working. It gives people a way to manage their yards to protect water quality and provide safe habitat for birds, pollinators, and people.
  • Restoring Meadows & Collecting Pollinator Data. Your support has helped restore these meadows:
    •     McKeon Farm in Ridgefield (a wet meadow and a dry one) where a 3-year pollinator count will help provide metrics on what pollinator species return after restoration work. This data will help establish best practices for restoring insect biodiversity. 
    •    Allen’s Meadow in Wilton (behind the community gardens) which is listed as a birding hotspot by the Audubon Society. The new meadow will take the place of a former refuse mound! Join us for spring and fall bird walks there.
    •    Along the Norwalk River Valley Trail (NRVT) (at Sharp Hill in Wilton, at Oyster Shell Park, Woodward Ave Park, and the Deering & Kellogg ponds in Norwalk). As new sections of trail go in, land is disturbed—much of it along the Norwalk River or tributaries. NRWA helps to plant these areas before the invasives take root AND to restore older sections, like the parking area at Sharp Hill in Wilton where we are also collecting data on returning pollinators.
  • On-going Tree Canopy Restoration & Native Garden Planting at Oyster Shell Park in Norwalk. An amazing team of dedicated volunteers meets every Wednesday and Saturday to restore the park’s gardens and riverbank by removing invasive species, planting native trees, shrubs and perennials.  The group has created the new Friends of Oyster Shell Park to support this work. 
  • Ongoing restoration at Woodward Avenue Park in South Norwalk.  Partnering with the city of Norwalk and through grants from FactSet, REI, the Nature Conservancy’s Community Resilience Building program, and the National Fish and Wildlife Foundation, NRWA has put in over 30 trees and is restoring a wetland area overrun with Australian phragmites to it native spartina grasses and shrubs, like groundsel and high tide bush.  Come take a look!
  • Partnering with Libraries for Virtual Webinars. Please check out our recorded webinars with partners at the Norwalk Public Library, the Wilton Library, and the Ridgefield Library. These webinars are on-going!
  • Challenging construction of “five football fields of berms and walls” along the Grupes Reservoir on the Silvermine River in New Canaan. After learning that the First Taxing District Water Department of Norwalk had failed to consider the environmental impacts of proposed dam- related construction at one of the most scenic and ecologically rich areas in New Canaan, we teamed up with the New Canaan Land Trust (NCLT) to become interveners in the hearing process. We hired dam engineering, wetland science, botany, and environmental law experts to study the potential impacts of the proposed plans. These experts presented their findings and our concerns to CT DEEP. The NRWA and NCLT incurred over $40,000 in legal and expert consultant fees in our fight to protect the Grupes Reservoir and the adjacent Browne Wildlife Sanctuary. Unfortunately we lost this fight, but we will continue to work to protect riparian buffers and wetlands in the watershed.

Laurie Mirra teaches yoga and works to restore wildlife habitat and protect water quality in South Norwalk. Laurie moved to the Village Creek neighborhood ten years ago and has been advocating since then for environmental protections in that community, encouraging homeowners to stop using pesticides on lawns, to use nontoxic mosquito/tick treatments, to plant for pollinators, to help her start a tree planting program, and to protect healthy trees.  Much of her energy in the last five years has focused on restoring Woodward Avenue Park in South Norwalk which lost most of its trees during hurricane Sandy. As neighborhood liaison to the city of Norwalk’s Tree Advisory, she has long advocated for restoring the tree canopy in South Norwalk. She helped organize a collaborative effort by NRWA, Village Creek, Recreation and Parks, and the Department of Public Works to remove invasives and plant native shrubs and trees, transforming Woodward Park.  In addition, the park’s new garden is now part of the pollinator pathway. Plans to connect Woodward and Oyster Shell Parks through a corridor of pollinators-friendly trees is one of the NRWA projects she is helping spearhead. As a yogi, Laurie says she lives by the practice of ahimsa or non-harming, which is an important part of an ancient philosophy that includes the practice of compassion for all living things. Ahimsa means not harming the complex web of nature that connects us all, including plants and trees, water and air, and our pollinators. She also is inspired by Doug Tallamy’s ideas around enriching biodiversity and protecting our environment, starting in our very own backyard.
