AWRA Webinar – Crowdsourcing and wicked water quality problems

Webinar – January 24, 2018 @ 12:00 CT / 1:00 ET

Speaker: Alan Kolok, Director, Idaho Water Resources Research Institute, University of Idaho

This webinar provides evidence to support the scientific merits underlying crowdsourced water quality data, and also contends that well designed citizen science campaigns can address wicked water quality problems. To demonstrate the utility of crowdsourced data collection, we initiated two citizen science campaigns within the Mississippi River basin.

Reducing how much nitrogen enters a lake has little impact on algal blooms.

WINNIPEG, Dec. 18, 2017-Lakes suffering from harmful algal blooms may not respond to reduced, or even discontinued, artificial nitrogen loading. Many blue-green algae responsible for algal blooms can fix atmospheric nitrogen dissolved in the water, and therefore water stewards should focus their efforts on removing phosphorus from lakes to combat algal blooms.

This is according to a recently published article in Springer’s Ecosystems journal, Biological Nitrogen Fixation Prevents the Response of a Eutrophic Lake to Reduced Loading of Nitrogen: Evidence from a 46-Year Whole-Lake Experiment.

 

Lake, campground in Riding Mountain National Park closed after discovery of zebra mussel DNA

CBC News, Dec. 12, 2017 – Parks Canada has closed a lake and campground in Riding Mountain National Park to the public after DNA evidence of zebra mussels was found in water samples taken this summer and fall.

In a news release, Parks Canada said Whirlpool Lake, on the eastern side of the southwestern Manitoba park, and its campground area are closed until further notice as a precaution.
