Characteristics

  Scugog River shoreline planting
  Volunteers, along with City of Kawartha Lakes and Kawartha Conservation staff, plant native species on the shoreline at 50 Wolfe St. to protect the shoreline from erosion and geese, and to filter nutrients in surface water runoff.

The Scugog River subwatershed is centrally located in the Kawartha Conservation watershed. It is situated between Lake Scugog and Sturgeon Lake, and is bisected by Hwy 35 and Hwy 7. It is roughly centered on the town of Lindsay, which covers a large portion of its landmass.

Water flows northward through Lindsay into Sturgeon Lake.

2013 Grades

The follow grades are based on monitoring data from 2012 to 2017.

Surface Water Quality

IndicatorResultGradeStatus
Total Phosphorus 0.027 mg/L C Fair
Benthic Macroinvertebrates N/A N/A N/A

The surface water quality grade was based on Total Phosphorous and/or Benthic Macroinvertebrates (aquatic insects).  A TP value below 0.03 mg/L (rivers) or 0.02 (lakes) meets the provincial guidelines and is in the B (good) or A (Excellent) grade range, while the result for Benthic Macroinvertebrates must be 5.00 or lower to receive a B (Good) or A (Very good to Excellent) grade.

 Forest Conditions

IndicatorArea CoverPercent CoverGradeStatus
Forest Cover 3.4 km² 7.5% D Poor
Forest Interior 0.2 km² 0.5% F Very Poor
Forested Riparian Cover 0.8 km² 19.9% D Poor

The combined forest conditions grade for the Scugog River subwatershed is ranked as poor.

Groundwater Conditions

Well 432

IndicatorResultIndicator GradeCombined Grade
Nitrate + Nitrite 0.043 mg/L A B
Chloride 191.0 mg/L D

Nitrogen levels are excellent and fall below the Provincial Drinking Water Maximum Acceptable Concentration of 10 mg/L. Chloride levels are slightly elevated, but still fall below the Provincial Aesthetic Objective of 250 mg/L for drinking water. Groundwater quality results from the wells do not represent groundwater quality across the subwatershed, but rather, the water quality within the aquifer in which the well is located.

Actions

The Scugog River subwatershed includes a large amount of urban, or built-up, areas. Nutrients and other contaminants on lawns, driveways, parking lots, and roads can be easily washed into the stormwater system, and out into the river. Property owners have an important role in protecting the water quality in the river, which also impacts Sturgeon Lake.

Urban property owners

Runoff through the stormwater system from residential and commercial areas can add a high concentration of phosphorus and other contaminants. As a property owner in the subwatershed, whether residential or commercial, you can help by reducing fertilizer use, picking up pet waste, preventing soil erosion, and keeping oil and other toxic fluids from dripping onto the driveway, lawn, or parking lot. Click here for more about urban stewardship.

Farmers and rural property owners

Agricultural operations in the subwatershed, which make up over 55% of land use, need to ensure soils do not erode, while minimizing nutrients in surface water runoff. Click here for tips on nutrient reduction and erosion control.

Trees could also be planted to increase forest cover, and help filter surface water. Natural cover along the river is especially important, as it also helps reduce erosion of the banks. Click here for more about trees.

The amount of existing wetland also needs to be increased, where possible. Click here for more about wetlands.Click here for more about wetlands.

River-side property owners

Healthy shorelines contribute to the health of Scugog River and Sturgeon Lake. Create or maintain a 3 metre or larger buffer along the river using native plants with deep roots. The plants will help prevent soil erosion and ice damage with their roots, and filter nutrients and other sediments in surface water runoff to the runoff. Avoid cutting the grass all the way to the water. Click here for more about shoreline protection.
