New tool will boost coordination between lakes: try out the interactive map!

by David Cordner

Washington State Lake Protection Association (WALPA) helps lake associations and watershed stakeholders coordinate and cooperate to protect lakes. To support this mission, the Center for Spatial Information and Research (CSIR) in Central Washington University’s Geography Department has partnered with WALPA to develop a Web-based interactive map of active lake associations in Washington and Idaho.

Harmful algae blooms are on the rise – help us track related illnesses!

by Joan Hardy

Has your lake experienced more algae blooms in recent years? You’re not alone. Washington is one of many states experiencing increased harmful algal blooms (HABs) in lakes, ponds, streams and rivers. Since HABs are an emerging public health issue, state and local health jurisdictions (LHJs) are concerned with toxic blooms, as are lake managers, lake residents, and those who use lakes for recreation. In Washington, liver toxins called microcystins are most prevalent; around 100 types are currently known. The next most frequently observed cyanotoxin in our state is anatoxin-a, a nerve toxin.

Freshwater Algae in Northwest Washington – a Beginner’s Guide to Algae

by Dr. Robin Matthews

To help make algal identification more accessible to students in my Freshwater Algae class, I am writing a series of taxonomic guides to algae in Northwest Washington…
I have had a life-long fascination with the microscopic world in freshwater lakes and streams. As a child I loved to collect samples from the local “ditch” to look at using my student microscope (best birthday present ever!). I took my first algae class in 1973 from Gerry Prescott, and it changed my life. What I have learned in over fifty years of study is that the microscopic world contains an astonishing ecological complexity.

Arsenic in lakes in the Puget Sound Lowlands: mobility and bioavailability 30 years after smelter closure

By Jim Gawel, Ph.D., Anthony Endresen, Erin Hull, Amina Kedir, and Corey King,  Rebecca Neumann, Ph.D., and Pam Barrett, Ph.D.

Arsenic, a priority Superfund contaminant, neurotoxin and carcinogen, is a ubiquitous contaminant polluting many urban surface water bodies. (A majority of Superfund sites are located in densely settled areas and 139 sites have arsenic-contaminated surface waters.) However, the human health and ecological implications of this contamination are unclear due to an incomplete understanding of arsenic bioavailability in urban waters, which are typically affected by eutrophication.
