Our Land Use Choices Affect Watershed Health
by Ann Sullivan
In late April 2018, a load of silt from Forestry Road 1852A slid into a reach of Silvester Creek, a tributary of the Elbow River. The incident might have gone unreported if hikers in the area hadn’t noticed unusually cloudy water and followed the sedimentation to its source. Their action led to a report to the Alberta Minister of Agriculture and Forestry and a formal complaint with the federal Department of Fisheries and Oceans.
Federal and provincial governments are still investigating the incident, but the damaged creek crossing, where the silt originated, has been repaired. When asked about the siltation incident, Ed Kulcsar, Vice President, Woodlands, at Spray Lake Sawmills (SLS), said in an email that the report was “inaccurate.” He added that “seasonal maintenance is performed to ensure all erosion control measures are functioning when conditions permit.” Cochrane-based SLS holds the Forest Management Agreement (FMA) for all Kananaskis Country forested areas—outside of protected areas and parks—in the Elbow River watershed. Its FMA was renewed in 2015.
The Government of Alberta confirmed that “the particular case in question is under an active investigation by both provincial forestry and federal authorities” and could not comment further.
The health of all creeks in the Elbow River watershed is crucial to our freshwater supply, but Silvester Creek is of special importance: It has been designated as critical habitat for Westslope Cutthroat Trout, a threatened species that some argue should be classified as “endangered.” (Click to read our article on this). Westslope Cutthroat Trout need clean, cool water and a pebbly bottom in which to lay their eggs. Extra sediment turns the water cloudy and the creek bottom into something more like concrete than loose pebbles. Conservationists see the muddying of Silvester Creek—a relatively small but vital piece of the Elbow River watershed—as evidence that land use of any kind can have an impact on the environment. The province acknowledges this and says its forestry division is working with other government programs to manage land use and fisheries issues in the Elbow watershed in general and the Silvester Creek area in particular.
