Spring Creek Inlet Total Suspended Solids

TSS is a measure of suspended particles in water. These particles can be soil from erosion and/or algae. High TSS corresponds with low water transparency and clarity.

TSS at the Spring Creek inlet to Pelican Lake is somewhat lower than TSS in Spring Creek at the Sherbrooke Culvert (see results). This is probably due to the fact that the water goes through a wetland, which is a natural filter, before entering Pelican Lake.

Spring Creek TSS concentrations range from 0.5 to 17 mg/L. TSS loading ranges from 0 to 600 lbs per day. Sediment is most likely being deposited here because of the amount of loading and concentration. The rate of sediment buildup is small. At the current rate it will take many decades for its results to be seen visually or have any impacting effects. Beaver activity south of the Sherbrooke culvert has caused significant erosion of the wetlands. The access sediment is being deposited into the unnamed lake between the Sherbrooke culvert and Spring Creek inlet. The effects can be seen where the stream enters the unnamed lake. Sediment build up has made a large shallow area where there is new heavy aquatic vegetation.
