The City of Lethbridge says Henderson Lake is seeing little algae bloom and cyan-o-bacteria levels this summer thanks in part to weather.
Two employees from Lethbridge Polytechnic, Tyler Branson and Jin Kim, monitor the lake’s water every two weeks by collecting samples to measure oxygen levels, take nutritional analysis and monitor algae concentration.
Phosphorus can fuel algae growth especially in hot weather. It was what caused a cyan-o-bacteria advisory last summer, but cooler temperatures and heavy rainfall have caused levels to remain low this year. The City says the work of the two men helps keep tabs on the state of the lake in order to ensure safety for all people and pets surrounding it.
Regular copper algaecide treatments from the City additionally helps maintain algae levels to a minimum. Detailed reports of the lake’s health will also be compiled at the end of the season.
