What it can and can't tell you
Every result shows the date and time the sample was collected. Results reflect one sample, collected at a specific place and depth, and analyzed by an independent accredited laboratory using the method listed on this page. Lake conditions change across a lake and over time, sometimes within hours, in ways a single sample may not capture. Every method has detection and reporting limits; where the laboratory provides them, they are reported with your results. A detection is not a diagnosis, and a non-detection does not prove absence. Results are not a regulatory or compliance determination unless the agency involved accepts them as one. Lake Pulse reports measurements; it does not determine whether water is safe for swimming, drinking, pets, or recreation. Always follow posted signs and your state or local health advisories. Recommendations are options to consider; decisions, and responsibility for any action taken, rest with you. Bacteria levels can change within a day, especially after rain. Official swim advisories and beach closures are issued by your local health authority.
