Anderson Lake Remains Closed–Toxin Levels High – PDN

The level of a fast-acting nerve poison in Anderson Lake has leaped to more than 500 times the warning level, according to results of tests taken last week. The lake between Port Townsend and Chimacum, which was closed May 3 this year because of elevated levels of toxins produced by blue-green algae, remains closed to recreation. The level of anatoxin-a, which can quickly cause convulsions and stop breathing, was measured at 534 micrograms per liter of water. The safety threshold is 1 microgram per liter.    Anderson Lake toxins highest of the year
