8.3.1 Spring Creek Inlet

Calculator

Spring Creek inlet flows underneath County Highway 20 and into Pelican Lake through a steel culvert. view calculator details

Total Phosphorous

Total Phosphorus concentration in Spring Creek ranges from 0.005 to 0.14 mg/L. Spring Creek deposits 0 to 20 lbs per day of TP into the Lake. view graphs

Chlorophyll A

Spring Creek Chlorophyll-a (CHLA) concentration generally ranges from 0 to 0.02 ug/L. ChlA loading is between 0 and 3 lbs per day. This concentration is extremely low. Algae grows better in calm water than flowing water. For comparison, the ChlA concentration in Pelican Lake ranges from 4-12 ug/L.

Because of the low concentration of chlorophyll-a detected in Spring Creek from 2002-2006, this test was dropped from analysis in 2007. view graphs

Fecal Coliform

Fecal concentration levels have typically remained in the safe, below 200 FC/100ml. Due to the relatively low levels, this test was dropped from analyses in 2007. view graphs

Total Suspended Solids

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. view graphs
