By Drew Pendleton; Dept. of Health and Welfare As temperatures increase, so does the likelihood of a cyanobacterial harmful algal bloom (cyanoHAB). CyanoHABs are caused by cyanobacteria, and the toxins they produce are harmful to humans, pets, livestock, and wildlife. CyanoHABs can change and increase rapidly if conditions are right. They favor warm water, sunlight, and specific nutrients in the water. These blooms can last throughout the summer into fall. The Idaho Department of Environmental Quality (DEQ) samples and analyzes Idaho water bodies for cyanoHABs. The test results are provided to the Idaho Department of Health and Welfare (DHW) and local public health districts, and they decide if a health advisory should be issued. For information on advisories, visit the DHW’s Idaho Recreational Water Advisories map for more information. The…
BoiseDev After toxins were found in Lake Cascade last month, the Idaho Department of Environmental Quality is holding an event for the public to learn more about cyanobacteria, cyanotoxins, and water quality monitoring at Lake Cascade. Representatives from a host of agencies, including DEQ, Idaho Fish and Game, Central District Health, and Cascade Medical Center will be on hand to answer questions about health effects and water quality. The open house is scheduled for Wednesday, July 13 at the American Legion Hall at 105 E Mill St in Cascade from noon to 6:45 p.m. While toxins were present in Lake Cascade in June, levels didn’t meet the threshold for a health advisory. Exposure to cyanotxins can cause skin irritation and an upset stomach. The toxins can be particularly harmful to…
I. Using Molecular Methods to Study Cyanobacterial Blooms. This presentation introduces molecular monitoring approaches used in the detection and quantification of cyanobacterial groups and cyanotoxin genes implicated in harmful algal blooms. Results will be presented from next generation sequence analysis and qPCR/RT-qPCR methods to characterize cyanobacterial community structure, associated bacterial community, toxic cyanobacteria, and geographically localized genotypes or species. The methods study cyanobacterial functional genes associated with nutrients in toxin production, their relationship to water quality parameters, and explore drivers of cyanotoxin production using mRNA-based sequence analysis. This presentation also discusses occurrence, distribution, temporal-spatial variations of cyanobacteria, especially toxin-producers, and use as early warning systems for cyanotoxin production. II. Funding Integration Tool for Source Water: Finding a Plan a FITS. With different funding mechanisms available, it can be difficult finding…

Invited speakers will provide an overview of federal funding programs from: National Oceanic and Atmospheric Administration (NOAA) United States Geological Survey (USGS) United States Department of Agriculture (USDA) Environmental Protection Agency (EPA) The forum will also include presentations from communities that have utilized funds from these federal programs as well as a session dedicated to…
