8.5 Pelican River Outlet
The Pelican River outlet is sampled at a culvert under South Pelican Drive. The river flows from Fish Lake under the road through 2 large concrete culverts and drains into Lake Lizzie.
The Pelican River outlet is monitored so we can compare the nutrients going into and out of Pelican Lake. This enables us to see what is retained in Pelican Lake.
Calculator The Pelican River flows under South Pelican Drive through 2 large concrete culverts. view calculator Total Phosphorous TP concentrations typically range from 0.005 to 0.04 mg/L, half of average stream in the ecoregion. Loading ranges from 0 to 40 lbs per day. view graphs Chlorophyll A ChlA concentrations range from 0.0005 to 0.016 ug/L. Loading ranges from 0 to 10 lbs per day. view graphs Fecal Coliform Fecal Coliform bacteria concentrations range from 0 - 150 colonies/100mL. This concentration is fairly low and does not pose a health risk to Pelican Lake. The two peaks in concentration ( shown on the graph ) were from non-typical rain events totaling 2.5 - 3.5 inches. Because of the typical low fecal coliform bacteria numbers in the Pelican River Outlet from 2002-2006 and the lack of direct possible sources of bacteria adjacent to the river, this test was dropped from analysis in 2007. view graphs |

Total Suspended Solids
The Pelican River Outlet TSS concentration ranges from 1-6 mg/L, which is relatively low compared with the inlets to the Pelican Lakes. The low concentrations make sense since this water is coming from Fish Lake. Due to the historically low TSS concentrations, this test was dropped from analysis in 2007. view graphs
Flow
The Pelican River Outlet flow ranges from 10-220 cubic feet per second (cfs) of water out of Pelican Lake. view graphs
