The surface water quality grade was based on total phosphorous (TP) and/or benthic macroinvertebrates (aquatic insects) family biotic index (FBI). The provincial water quality objective for TP in rivers and streams is 0.03 mg/L and 0.02 mg/L in lakes. These guidelines were set because levels highter than these guildelines provide conditions for nuisance algae and aquatic plant growth. A TP value below 0.03 mg/L (rivers) or 0.02 (lakes) meets the provincial guidelines and is in the B (good) or A (excellent) grade range, while the result for benthic macroinvertebrates must be 5.00 or lower to receive a B (good) or A (very good to excellent) grade.
