Information on Fish and Fish Habitat
in the Woodens River system
Asterisked documents (***) contain Water Quality data.
- Focus on fish & fish habitat*** (PDF)
The January 2011 issue of WRWEO’s newsletter, WRWEO WATCH, offers an overview of issues relating to fish and fish habitat in the Woodens River system. In an essay entitled “Where have all the mayflies gone”? Bob Chambers examines possible explanations for the precipitous decline of the spring mayfly in 1989/90 and the near simultaneous decline of the brook trout populations.

The Woodens River system is a Catch & Release Special Trout Management Area:
The following lakes in Halifax County will be catch and release only:
Birch Hill Lake, Blueberry Lake, East Duck Lake, Five Island Lake Five Island Lake Run, Frederick Lake, Holland Marsh Lake, Hubley Big Lake, Jacket Lake, Lizard Lake and Sheldrake Lake and Woodens River (downstream from the outflow of Hubley Big Lake, including all lakes and tributaries). Single hook lure or artificial fly, natural bait is prohibited.
- Nova Scotia Fly-fishing, Tying and Tall Tales
Two pages on Pat Donoghue’s website describe some of the history of trout in the Woodens River system and the challenges they face: Fishing on the Woodens River, Requiem for the Mill Pond. There’s lots else on this website related to fly-fishing, as well as some good fishing stories.

- An integrative approach to prioritizing aquatic habitat restoration sites in the Wooden’s River watershed, Nova Scotia***
2007 SMU Honours Geography thesis by Oliver C. Woods. This thesis deals with brook trout habitat in the Woodens River watershed. Posted with permission of the author.
- Woodens River Watershed Resource Analysis (PDF)
1993 report for the Three Brooks Homeowners Association by Elizabeth Tough (Nova Scotia College of Art and Design, Environmental Planning Studio 1).
A resource analysis used the overlay technique, which involves overlaying the various resources, in map form, to define sensitive areas and opportunities and constraints for maintenance of brook trout
habitat quality in the watershed. The resources considered were Vegetation and Land Use, Soils, Slope Aspect, Surficial Hydrology. Surficial geology, Structural Geology, Slope, Elevation. An original version with coloured Maps is available at the DAL Sexton Library (TC 426.5 W6 T6 1993). This PDF was scanned from B&W copy.

- 2009 Stantec Report on Biological, and Supporting Water Quality Studies, Woodens River Watershed*** (PDF)
“The purpose of the work was to assess general environmental quality (as represented by water
chemistry), and the biological condition of selected lakes (as represented by the benthic invertebrate
communities present in the spring, and observations of brook trout spawning areas in the fall…The benthic invertebrate study results and spawning survey information are intended to complement ongoing
studies related to the presence of PCB contamination in Five Island Lake, and the general population status
of brook trout (Salvelinus fontinalis) in the Woodens River watershed.”
- Habitat Survey of the Woodens River Watershed***
This study, conducted in 2000, employed three youth to carry out baseline habitat and water quality studies of streams throughout the Woodens watershed. The document provides data on a variety of stream habitat variables (amongst them: vegetative cover, pH and invertebrates).
