Staff reports lake tests below human-toxicity thresholds but above dog threshold; signage pending
Summary
Committee heard that two water tests for algal toxins were below human-health thresholds but exceeded the dog-level threshold for one toxin; staff said they have provided a sign to public works but it had not yet been posted.
Committee members were updated on recent algae testing at a city lake. Staff said the lake was tested twice; results were "well below" human-health thresholds for the tested toxins but both tests exceeded a lower dog-specific threshold for one toxin. Staff told the committee that the dog-level threshold for that toxin is 0.03 parts per billion.
Committee members asked whether staff had posted warning signage; staff said they had given Corey a sign about blue‑green algae to post but that the sign had not yet been installed. Staff and committee members discussed continuing monitoring; staff described the current level as below human drinking-water thresholds but high enough that pet-owners should be cautioned.
No closures or formal public-health orders were announced at the meeting; staff said they would continue to test and update the committee and would post signage as appropriate.
