Residents around Pattison Lake are being advised to stay clear of the water due to a toxic algae bloom, as reported by Thurston County Public Health and Social Services. Detected Microcystins toxin levels are at concerning levels, with recent lab results from September 30 indicating a measure of 9.0 ug/L, which surpasses the state's recreational safety threshold of 8 ug/L. These toxins are not just harmful — they can be downright dangerous, affecting both human health and animal well-being.
Microcystins, the culprits here, are liver toxins and are considered possible human carcinogens; their presence in water can also sicken pets and livestock that consume the water. The Public Health staff, in response, has committed to ongoing testing. They'll be back at the lake's edge weekly, vials in hand, until they can confidently report back-to-back weeks of safer toxin levels. But here's the kicker, even if the lake looks as clear as crystal, invisible dangers may still lurk beneath its surface.
Until the all-clear is given, it's strongly recommended that you don't treat Pattison Lake as your personal oasis. The health officials' advice is clear: don't drink the water, give the algae a wide berth, and keep your activities on dry land. Swimming, wading, windsurfing, or water skiing are all off the table where these blooms have been spotted. Pet owners, too, should steer their furry friends clear of the lake to avoid any potential illness.
Fishing enthusiasts should note that dining on catch from Pattison during this period is off limits. Boaters, meanwhile, should avoid the scummy areas — a visual clue of the bloom's presence. While these restrictions may seem severe, they are in place for the safety and health of the community. These guidelines come directly from the source and reflect a proactive approach to dealing with this environmental health issue.
