Report and Analysis of Water Quality 2017

FRENCH RIVER 2017 ANALYSIS of WATER QUALITY

 The 2016 sampling of 18 points along both the North and Main channels showed fairly significant improvements in Total Phosphorus levels compared to the 2007 to 2010 sampling project. Calcium concentrations and water clarity have remained fairly constant and present no concerns at this time.

Although Total Phosphorus levels improved, through local observations, we noted some areas of algae blooms. Although the 2016 year blooms were less dominant than prior years, they do require a review of our Report Card criteria which we plan to complete in 2017. This review may shift results to a more stringent criterion for the “A” Report Card rating in future years.

Looking at the actual results, a decrease in Total Phosphorus concentration was noted in 12 of 13 sample locations with 1 location showing comparable results to prior years. Although these results are encouraging we note that a one year sampling period is not a sufficient period of time to state with certainty any verifiable findings. Our current analysis of these results is provided in the comments section of the raw data report.

The actual raw numbers and current Report Card are attached to this cover letter.

Copies of this report will be sent for peer review as well as be posted on our website for comment.

FRENCH RIVER WATER QUALITY REPORT CARD

Ratings Legend: All readings based on ug/L (micro grams per litre) of Phosphorus.

A – Average 12 or lower with no results over 20.

B – Average 15 or lower with no more than 20% of then results over 20.

C – Average 15 or lower with more than 20% of results over 20.

D – Average 15 or higher.

F – Average 20 or higher.

The sampling data used was mainly from our work with the MOE lake partner program.

The FRSC’s Target is to get all areas of our river to an “A” rating.
