St. Thomas Academy students keep watch over Rogers Lake

For years, students from St. Thomas Academy have kept a close eye on “their” lake.

The school overlooks Rogers Lake in Mendota Heights, and students in the environmental sciences class have been studying the water quality of Rogers Lake in Mendota Heights since 2001. Students collect samples from the lake every fall, analyze them with an array of laboratory tests and present their findings to the Mendota Heights City Council in the spring.

During its March 4 meeting, the city council listened to the students’ presentations. The news was good: for the most part; the lake is doing well.

According to information provided by the students, Rogers Lake is maintaining its overall water quality level as compared to previous test results. Total phosphorous and total suspended solids levels continue to be right at the regulatory thresholds, with all other measured categories within compliance standards.

Overall, the lake received a “good” rating, with water quality improving since last year.

During the presentation, students encouraged residents who live near Rogers Lake to boost the lake’s health by composting, being more conscious about using fertilizer, cleaning up animal waste and disposing grass clippings in a proper manner.

After the presentation, Mayor Sandra Krebsbach thanked the group for their work and said she looked forward to seeing the students again next year.
