State of the Watershed
State of the Watershed brings together all of the current data and information we have about the watershed and makes an assessment of its health.
Find out what our lake health is like, where it used to be and how it could potentially look in the future.
The State of the Watershed Report (SOW) is a tool that can be used by present and potential users to determine the feasibility and sustainability of their projects. This report can be used as predicable information that alerts government, both provincial and municipal, to the importance of sustainable and prudent socio-economic planning and financing for future watershed development. To assess watershed health we use standardized watershed indicators as set out by the Government of Alberta so that all reporting is consistent.
Each of the 11 WPAC’s in Alberta have completed or are working on a SOW Report. The LSWC worked with Carson Forestry to complete the State of the Lesser Slave Watershed report in April 2010.

2015 Technical Update for Lesser Slave Lake
Throughout 2014 and early 2015 the LSWC worked with Hutchinson Environmental Science Ltd. and other partners to complete a technical update for the Lesser Slave Watershed.
The report includes:
- An aquatic assessment of rivers and the lake, including information on flow and water quality;
- a Phosphorus budget for Lesser Slave Lake based on different methods, a summary of paleolimnological data collected from two studies describing historical lake quality, including previously analyzed (geochemistry, pigments) and raw (organic contaminant, diatom) data;
- a BATHUB modeling exercise to predict lake water quality based on the P budget and development and restoration scenarios, prepared by AEP (formerly ESRD) and NSWA;
- and a summary of fisheries status and human limitations that affect them, prepared by AEP (formerly ESRD).
This report provides stakeholder and governments with important information based on the most current science and data available and has been in the works for several years. The LSWC completed nutrient monitoring on tributaries of Lesser Slave Lake throughout 2012 and 2013. AEP (formerly ESRD) staff collected sediment cores from LSL twice in the past 10 years and had them dated and analyzed. Fisheries information is based on 2012 surveys done by local fisheries biologists. AEP (formerly ESRD) staff and staff from the North Saskatchewan Watershed Alliance helped set up and calibrate the BATHTUB model for our lake and input the data sets.
In addition to the 170-page technical report Hutchinson has produced a summary document for the public that explains the project and presents the findings to a non technical audience. Both documents are listed above.
