NPR’s Here & Now Highlighted National Lake Appreciation Month
Steve Lundt, a Water Quality Scientist (Metro Wastewater Reclamation District in Colorado, USA) and a NALMS Certified Lake Manager (CLM), participated in an NPR Here & Now segment (aired around 1:45 pm on July 13th, 2017) highlighting National Lake Appreciation Month & the Secchi Dip-In!
If you'd like to hear audio from the segment (approximately 9 minutes, 18 seconds), visit http://www.wbur.org/hereandnow/2017/07/13/favorite-lakes
The photo of the Secchi disk used on the segment's website was provided by current Secchi Dip-In Program ...

NOTICE: Website Data Submission Temporarily Unavailable
Hello Secchi Dip-In Volunteers,
Thank you to all volunteers who alerted us about issues submitting data via the Secchi Dip-In website! Late Monday evening, it was determined all accounts are currently unable to submit data to the Secchi Dip-In website. The company managing our website-database interface has been contacted and we are waiting for a response.

Great Lakes HABs Collaboratory Aims for Collective Impact on HABs
The HABs Collaboratory follows the “Collective Impact” model, where individuals from a variety of different groups come together to solve a specific problem and are supported by a neutral backbone organization. The HABs Collaboratory provides a unique opportunity for researchers to interact with other researchers from a variety of disciplines and institutions and to facilitate the use of scientific information to support relevant decisions by managers and practitioners.
Cyanobacteria Monitoring Collaborative
The Cyanobacteria Monitoring Collaborative monitoring activities are carried out under three different program “tiers” that represent different monitoring objectives and complexity. Regardless of the level of expertise involved, all three programs (bloomWatch, cyanoScope, and cyanoMonitoring), in addition to professional monitoring entities, leverage the collection of data by crowdsourcing and citizen science.
Assessing Water Quality Trends in Affected Ontario Lakes
Unfortunately, for many lakes, long-term monitoring information on bloom history, productivity and nutrient levels, water column temperature, and other factors that may contribute to algal bloom formation often only exist for the last few years, if at all. Paleolimnology offers valuable insights into past environmental conditions to improve our understanding of current lake management issues.
Toxin Risk – Tools for Warning
Increased frequency and severity of cyanobacterial blooms suggests that toxins are a threat that must be taken seriously. However, not all cyanobacteria are toxic – so how can we know which blooms pose a health risk? We developed both now- casting and forecasting approaches based on a nine-year data set of microcystin concentrations collected biweekly from Buffalo Pound during summer months
Transport of Microcystins from Lakes & Reservoirs to Coastal Environments
While many cyanobacteria species can produce microcystins, these toxins are often associated with Microcystis, a genus that thrives in warm, nutrient rich waters. Although Microcystis is normally associated with freshwater ... it has been shown to survive in even higher salinities and can sustain growth for short periods in pure seawater.
Beyond Total Microcystins
Although there are over 100 known variants of microcystins, there remains a great deal of variation in the way microcystins are analyzed, quantified, and reported in the literature and by monitoring agencies. An important shortcoming ... is the reliable reporting of different microcystin variants, as well as the use of comparable laboratory techniques.
