2. Chinook Winds Golf Course expansion at the north end of Devils Lake
3. Wetland fill and erosion prevention alert
4. U.S. Fish and Wildlife Service funding support at the federal level. The Rock Creek dam project received their funds.
5. West Devils Lake near the LDS church proposed development

Recreational guidance levels for microcystin:
State of Washington - 6ppb
State of Vermont - 6ppb
State of Oregon - 8ppb

ppb - parts per billion

Protecting children and elderly
Oregon’s guidance value of 8ppb for microcystin was derived using 20 kg as the default child body weight.
Posting is intended to provide the public with information that indicates a public health hazard might exist. A further notice should warn that children, individuals with pre-existing medical conditions, and the elderly (and pets) are considered susceptible populations.

• Oregon Department of Human Services - Cyanobacteria advisories www.oregon.gov/DHS/ph/hab
• DLWID contacted Lake Oswego and received pictures of a boat built to skim the water for debris, but not algae. An aquatic weed harvester is used. Alum is used to help deter algae.
• Washington State Department of Health - Cyanobacteria were previously grouped with algae but are now classified as bacteria after analysis of cell structure and cell division. They differ from other bacteria in that they contain photosynthetic pigments similar to those found in algae and plants. Although they are predominantly photosynthetic (light-dependent) organisms, they are also capable of using organic compounds as a source of energy. Some cyanobacteria have a specialized structure called a heterocyst that can fix molecular nitrogen. The ability to fix nitrogen gives these species a competitive advantage over other algae. Many cyanobacteria have gas vacuoles that allow them to remain in suspension and migrate to surface waters where there is plenty of light for photosynthesis. On the surface, colonies may clump together and form a scum which can cause water quality problems in lakes. www.doh.wa.gov

Blue-green algae deterrent methods considered - SolarBee explored

CYANO-WATCH: The Devils Lake Water Improvement District is embarking on its fourth year of the CYANO-WATCH program. A three pronged approach, the Cyano-Watch program is designed to educate about (GREEN), caution (YELLOW) or restrict (RED) the use of Devils Lake. See the sample flyers that are posted during Phases I, II, and III of the program. This program has been developed based on Oregon DHS: Public Health Advisory Guidance for Toxigenic Cyanobacteria in Recreational Waters.
This year DLWID will be conducting routine toxicity monitoring in conjunction with the identification and enumeration done in years past. The season when cyanobacteria flourish is generally July - September, so lake users should be aware of precautions to be taken when bloom conditions exist. Always watch and stay clear of cyanoblooms or scummy water, keeping both children and pets safe.

It is important to note that cyanotoxins produced by cyanobacteria can remain in the water for up to two (2) weeks after a bloom has vanished.

Bacteria bloom puts Goss Lake on Whidbey Island out of use
LANGLEY -- If the blue-green algaelike bloom on Goss Lake doesn't clear up soon, participants in the 13th annual Whidbey Island Triathlon and kids on vacation may have to swim somewhere else, come summer.
   Island County Public Health department officials have posted caution signs at Goss Lake since December, when the cyanobacteria first showed up. A test to identify the bloom and its toxicity several months ago revealed low levels of toxins.
