2. Methodology

2.1. Study area

Mattatall Lake is located on the Cumberland/Colchester County line and is approximately 5-kilometer length (Fig. 1). Mattatall Lake is mainly spring fed with multiple brooks. There is an outlet from the lake draining into the French River, then draining into Northumberland Strait. In 2011 some small blooms were first noticed on the lake by lake residents beginning in late June early July; however, they dissipated by September. Over the past 2 years the algae blooms have gotten gradually worse and late September 2014 the bloom totally expanded, covering the entire lake until December 2014.

2002), phosphorus levels in soil within the watershed and in surface water samples will be considered to determine the potential sources of nutrient loading into the lake. Different samples and analyses for Phosphorus concentrations (and hereafter we call Total Phosphorus – TP) in brooks and ponds of the ML watershed gave us a panoramic view of nutrient sources streaming to the lake and how they could disperse and redistribute in the lake waterbody. The term ‘Total Phosphorus’ has to be understood as all forms of Phosphorus which may occur mostly in Phosphates (PO4) and Organic Phosphates.

Nitrogen in the lake is detected under the forms of Ammoniacal Nitrogen, Nitrate, and Nitrite. These three types of Nitrogen formed a parameter named Dissolved Inorganic Nitrogen (DIN). This factor DIN couples with the organic form of Nitrogen to define Total Nitrogen (TN). Total Nitrogen and Total Phosphorus are two of the most important micronutrient components for algal development and hence very important parameters to be used for predicting scenarios of algae bloom occurrence and

Chlorophyll-a is a specific form of Chlorophyll, used in oxygenic photosynthesis. Measurement and determination of this parameter are the basic analysis to evaluate the characteristics of algae blooms in many research works in the world. Unfortunately, Chlorophyll-a represents just the whole quantity of photosynthesis pigment released from all algae and micro-plants present in water, hence it cannot help to distinguish cyanobacteria existence among all living micro plants and algae in the waterbody. To be able to define and confirm the existence of Cyanobacteria species in the composition of aquatic microalgae, another pigment form, Phycocyanin, is used. Phycocyanin is the pigment, which differs cyanobacteria species from another planktonic species, and could give us a real picture of quantity of cyanobacterial genera in the water. Phycocyanin is actually a pigment-protein complex from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin. It is considered as an accessory pigment to
