Save Sawmill River

After 46 years of being buried underground, the Sawmill River can see daylight again! You can now visit the river, which is back flowing above ground at Sullivan’s Pond in Dartmouth. This is an important step in reviving fish passage between Halifax Harbour and the Shubenacadie River system for species such as gaspereaux.

The Sawmill River is a historic river that once flowed through downtown Dartmouth. In 1972, after extensive flooding caused by Hurricane Beth, the river was buried into a stormwater sewer. The City of Halifax is now embarking on a once-in-a-lifetime opportunity to expose and restore Sawmill River.  Halifax Water is in the process of replacing the aging culvert in which the Sawmill River now flows between Sullivan's Pond and the Halifax Harbour.  

Daylighting, the practice of exposing streams from buried conditions, will allow for all or parts of the river to flow above ground adjacent to the Canal Greenway Park.  It will have many benefits for Dartmouth residents and visitors alike, including improved land value, recreation and amenity space, flood risk management, fish habitat improvement, urban-heat-island cooling, and wellbeing.  

Phase one of this project is complete, and parts of the Sawmill River can see daylight once again. While we’re pleased that the river is flowing above ground, it is contained in an engineered channel. This channel, however, is complete with a fish ladder so that the fish will be able to move from the ocean to the many lakes upstream. This phase ends in the temporary holding pond behind the Lock 9 Condos.

Project Timeline:

2006 - Feasibility Report
The Canal Greenway Phase II report prepared by a team of consultants in 2006 and commissioned by HRM shows that daylighting Sawmill River is feasible (see image above)!

November 2014 - Sawmill River Petition Launches
We launched a petition asking Halifax Regional Council and Halifax Water to support daylighting the maximum portion of Sawmill River between Sullivan's Pond and the Halifax Harbour. The petition garnered more than 500 signatures.

January 20, 2015 - Town Hall Meeting 
Approximately 280 people were in attendance for a town hall meeting on daylighting the Sawmill River. Many thoughtful and insightful questions were posed from the audience. 

April 19, 2015 - Human River Walk
Over 200 Dartmouth residents took part in the Human River Walk to celebrate the historic Sawmill River. 

May 7, 2015 - Staff Report
Halifax staff released an information report on daylighting Sawmill River.  Click here to access the staff report.  The report was requested by Councillor Gloria McCluskey following a presentation by the Ecology Action Centre to the Harbour East Marine Drive Community Council on November 13, 2014.

July 2015 - CBCL Report
A report commissioned by Halifax Water to explore and analyze options for replacing Sullivan's Pond storm sewer was made available through a freedom of information request by the Chronicle Herald.  The report recommended a combination of a concrete box culvert (4 m x 4.3 m) and an open channel located on Halifax Water's existing storm sewer easement.  Both the culvert and the open channel would provide fish passage.

August 2016 - Funding from the Federal Government
The federal government announced funding under the Clean Water and Wastewater Fund for a number of projects including the project which involves Daylighting the Sawmill River, the Sullivan’s Pond storm sewer renewal. The province committed over $2.1 million to this project and the federal government allocated over $4.2 million. 

Spring 2018 - Phase One
This spring, Halifax Water completed phase one of the project. In February, the Sawmill River saw the light of day for the first time in 46 years! The partial daylighting will allow for parts of the river to flow above ground adjacent to the Canal Greenway Park. The city is also landscaping beside the river (spring 2018) to add grassy areas (perfect for picnics), as well as some trees.

Additional Background and History:

Click here for a detailed description on the case for daylighting Sawmill River

 

"Daylighting in Halifax’s Urban Core: A case study-based analysis of the proposed daylighting of Sawmill River in Dartmouth, Nova Scotia" by Darryl McGrath, Masters of Planning student, Dalhousie University.  

Daylighting brings buried waterways back to life by uncovering and restoring them.  Daylighting rivers can reduce polluted runoff, improve fish habitat and revitalize our urban spaces.  This practice has been done around the world and many cost-effective examples exist in the USA, click here to read a report by the Rocky Mountain Institute entitled "Daylighting: New Life for Buried Streams"

Prior to the founding of Dartmouth in 1749 the waterways that became Sawmill River were used by the Mi'kmaq for navigation between the Harbour via the Shubenacadie River to the Minas Basin.  A series of locks were built in the 1820s that allowed for larger ships to travel between the Minas Basin and the Halifax Harbour.  Saw Mill River was buried in 1972 after Hurricane Beth dumped over 235 mm of rain in 30 hours and caused localised flooding. 

 

Today, the corrugated steep pipe in which Saw Mill River flows is undersized for the area of land that drains into it and needs to be upgraded.  Several opportunities exist that can be leveraged in favour of daylighting:

  1. The Department of Fisheries and Oceans has required that Halifax Water provide fish passage.  Fish are more successful at swimming up a sun-lit channel than a long, dark pipe. 
  2. HRM's policy on River Daylighting was approved by Regional Council in 2006.
  3. New development planned in downtown Dartmouth will require associated greenspace in the form of parks and walking trails.  A daylighted river would be an aesthetically pleasing amenity to these parks.
