Caution: Since Russell Lake is a shallow lake, the standard limnetic (i.e., open-water) trophic parameters may not represent the true trophic status of the lake.
Chemical vs Biological monitoring
Select scientific modelling and chemical/biological limnology are part of our miscellaneous archives
The bathymetric map; the morphological data; the location map; the Cow Bay River watershed flow chart; the paleolimnology of lakes in the HRM; and the first ever study in Nova Scotia utilizing the Lake Evaluation Index (LEI) developed by the USEPA's Corvallis Research Lab
- Russell Lake, Dartmouth-Paleolimnology results from an NSERC funded research project, 2000's-archives from our files; January 16, 2013
Future and monitoring:
It is hoped that further investigations will be carried out by us along with chironomid mentum deformity studies of this valuable urban lake.
Since Russell Lake is a shallow lake, the standard limnetic (i.e., open-water or pelagic) trophic parameters may not represent the true trophic status of the lake.
The limnetic parameters may not reflect changes in the watershed unless those changes are significant in relationship to the overall size of the watershed and/or in its prevailing inputs!
To reliably ascertain incremental inputs from new developments, outflows of every storm pipe outlet, of in-situ devices (e.g., CDS, Stormceptor or Vortechnics), of constructed wetlands outlets, and others have to be monitored almost on an hourly basis during runoff, and pollutographs have to be developed.
Total stormwater treatment recommended:
Total stormwater treatment should also include removal of other urban pollutants as well, not just phosphorus! The CDS technology, the Stormceptor, and the Vortechnics are superb devices for pre-treatment, but they have to be followed by sophisticated polishing systems, for example a scientifically designed wetland with the attendant maintenance in perpetuity! This combination may or may not work (see the note of caution)!
A note of caution: There have been conflicting results in the long term removal of typical stressors in storm drainage using constructed (or engineered) wetlands. Further, such wetlands have not had a successful history in the amelioration of acid drainage in HRM. Hence, the only sustainable methodology would be treatment of urban and suburban stormwater by traditional wastewater treatment plants (WWTP) based on the tertiary removal process in the case of stressed lakes! This implies considerable capital costs and operation & maintenance!
The other option is to disallow any further development similar to what residents in Lower Sackville triumphed at Second Lake after years of intense lobbying! Even there, significant amount of chemical and biological limnology was conducted by us!
