For the past few years, Clean has focused on the restoration of Ellenvale Run, a main tributary of the Cow Bay River Watershed. The stream originates from its headwaters at Topsail Lake and Lemont Lake, and flows south through four heavily urbanized communities within Dartmouth. The watercourse flows for approximately 3.3 kilometers through natural riparian areas, a series of culverts, gabion walls, and underground pipe before draining into the northwest end of Morris Lake.
Through electrofishing, Clean has observed various native fish species including Brook trout, Brown trout, American Eel, Alewife or Gaspereau, and Banded killifish in addition non-native Smallmouth bass and Chain pickerel. Russell Lake Brook flows from Russell Lake into Ellenvale Run through a wooded area beside the Portland Lakes Trail.

In 2011, more stream bank was stabilized and secondary channel braids were blocked in the Portland Estates area. Near the Portland Street Superstore Portland Street, two digger logs were installed and one section of the bank was stabilized. Fish passage at a culvert under Patterson Drive was improved. In Commodore Park, two digger logs and a deflector were installed and a section of bank was stabilized. A total of 85 trees and shrubs were planted, 51 of which were planted with the help of volunteers from the community.
In Russell Lake Brook, one rock deflector, two trail side bank stabilization, and a series of cover rocks were installed. A fish passage structure was placed at the outflow of Russell Lake to improve passage into the lake.
A large amount of debris and garbage was removed throughout Ellenvale Run. Most of the garbage clean-up was assisted by volunteers over a two week period and one community pick-up. During these events, nearly 200 bags of garbage were removed in and along Ellenvale Run in addition to 24 shopping carts!
