Our latest laboratory sample found 9,228 total algal cells per millilitre, with 8,530 of those identified as cyanobacteria (blue-green algae). While cyanobacteria made up most of the microscopic algae in this sample, the type of cyanobacteria present is just as important as the numbers themselves.

The sample was dominated by Aphanocapsa delicatissima, a common species that is not typically associated with harmful blooms or significant toxin production. The lab also identified deteriorating Anabaena (also known as Dolichospermum), which suggests this population is breaking down rather than actively growing. Overall, these findings indicate that cyanobacteria remain present in Nicola Lake, as we would expect during the summer, but there is no indication from this sample of a rapidly developing or severe bloom at the sampling location.

Another encouraging sign is that our recent Secchi depth measurement was 7.4 metres, indicating excellent water clarity for this time of year. At the same time, it's important to remember that clear water doesn't always mean cyanobacteria aren't present. Many cyanobacteria are microscopic and remain suspended throughout the water column, which is exactly why laboratory monitoring is so valuable.

One thing these results cannot tell us is whether toxins are present. Not all cyanobacteria produce toxins, and even those that can don't produce them all the time. The only way to know whether toxins are present is through laboratory toxin testing. That's why we look at the whole picture—species present, cell counts, water clarity, visual observations, and laboratory analysis—rather than relying on a single measurement.

Based on these results, there is no reason for people to avoid enjoying Nicola Lake. Swimming, boating, paddling, fishing and other recreational activities can continue as usual. As always, we recommend avoiding any areas where you see thick surface scums or water that looks like pea soup or spilled paint. Dogs, especially puppies, are more susceptible because they tend to drink lake water, so it's best to keep them away from any visible accumulations.

The most important takeaway is that this is one snapshot in time. Wind, temperature and changing weather can move and concentrate cyanobacteria from one part of the lake to another, sometimes within hours. That's why Guardians continues to monitor the lake throughout the summer. Every sample helps us build a clearer picture of what's happening, and we'll continue sharing those results with members so you have the best available information.

Overall, these latest results are cautiously encouraging. They tell us that cyanobacteria remain a natural part of Nicola Lake's ecosystem during the summer months, but they do not indicate a significant bloom at our sampling location. We'll continue working with our scientific partners to monitor conditions closely and keep you informed so everyone can enjoy Nicola Lake safely and responsibly this summer.
