Gibbs Lake Closed Due To Toxin

 
GIBBS LAKE CLOSED DUE TO TOXIN
 
July 18, 2013: Port Townsend High levels of the toxin microcystin were detected in water samples taken from Gibbs Lake on Monday, July 15. As a result, Jefferson County Parks and Recreation has closed the lake for recreation including fishing, boating and swimming. Visitors are also urged to keep pets out of the water. The rest of Gibbs Lake County Park remains open for hiking, biking and horseback riding. Microcystin is produced by bluegreen algae, also known as cyanobacteria, and can result in illness in people and animals. The toxin level this week climbed to 6.9 micrograms per liter, which is over the Washington State recreational criteria of 6 micrograms. 
 
Jefferson County Public Health (JCPH) has seasonally monitored area lakes for bluegreen algae since 2007. Monthly monitoring of Anderson, Gibbs and Leland lakes began in April of this year. Anderson Lake closed due to toxins in May. Gibbs Lake has had toxic algae blooms in the past, but seldom have the toxin levels risen above the recreational criteria.
 
To check the status of Jefferson County Lakes and learn more about toxic cyanobacteria monitoring, consult the JCPH website at www.jeffersoncountypublichealth.org/index.php?lake-water-quality or call (360) 385-9444.
