Safe Drinking Water Advisories
St. Mary Parish: A BWA has been issued for the City of Franklin as the Franklin Water System has experienced a string of power surges and drops in water pressure over the last two days. The Boil advisory impacts all customers until further notice.
Acadia Parish: The Village of Estherwood is under a boil water advisory due to a broken line until further notice.
Lafayette Parish: Carencro issued a Boil Water Advisory following a construction accident yesterday, a contractor cut through a water line on Benoit Road. The order impacts customers on Desoto Road, Benoit Road, Mills Street, Gourmet Road, W. Gloria Switch Road, Androcles Road, La Rue Des Renards, Lynda Street, and Gayle Road.
Lake Fields in Lafourche Parish has sparked up a lakewide bluegreen algal bloom currently leading the larger Louisiana water bodies for extreme high concentration, as high as 3 million cells per 100 ml. A small retention pond north of Burnside has gone right off the chart for high concentration, we cannot count it any higher, in the latest image from NCCOS captured August 20, estimated over 6 million cells per 100 ml sample.
National Centers for Coastal Ocean Science (NCCOS) HAB monitoring program focuses on nine projects in the USA for near daily updates. The NCCOS is part of the National Oceanographic and Atmospheric Administration (NOAA), which is part of the multi-agency effort to detect bluegreen algae in freshwater lakes of the USA. The Cyanobacteria Assessment Network (CyAN) provides an eye-in-the-sky satellite view to detect and estimate the concentration of algal blooms widely in the USA. The US EPA heads this program with public access via internet, besides the NOAA there is the National Aeronautics and Space Administration (NASA), the US Geological Survey (USGS) and the US Army Corps of Engineers (USACE), the "research supports federal, state, tribal, and local partners in their monitoring efforts to assess water quality to protect aquatic and human health".

Louisiana: The latest upload from the NCCOS is dated August 20, taken at wind speed 8.3 mph, a clear capture showing Lake Pontchartrain clear of HABs another day, or HABs too low concentration to observe. A very high concentration lakewide HAB in Bayou Fortier peaks at 3-4 million cells per 100 ml in the east half, the Lac des Allemands west bay also reaching 3-4 million concentration. Lake Fields is completely socked in with HABs 3 to 4 million cells. Lakes Verret and Palourde lakewide HABs chug along at a consistent 700-800 thousand cells per 100 ml as observed all season. Check out the latest satellite image from NCCOS here.
New York
The latest image of Lake Champlain was captured yesterday, Aug 20, another day of heavy cloud conditions. A previous image caught Aug 18 showed a slice of the northeast Baie Missisquoi HAB between clouds, concentration down to 600 thousand cells per 100 ml. The last clear image was acquired August 14, this same bluegreen bloom on that date at concentration 1 to 3 million cells per 100 ml. See our NY HAB report for more details here.
From NYS Department of Environmental Conservation: One hundred and thirty-seven active HABs midweek, up from 126 yesterday including the first bluegreen reports of the season for Lake Carmel and Sagaponack Lake. See the impacted water bodies list here, updates are in progress as new reports are confirmed.
Lake Erie west basin
Algal toxin advisories have been issued for two Lake Erie State Park beaches this week Monday. Maumee Bay State Park on the second algal toxin advisory of the season, this one posted August 19, a month to the day after the first advisory. The HAB in this location has been parked right up along the shoreline, cooking up a high concentration for weeks, as detected by the NCCOS.
The latest satellite image of Lake Erie West basin was captured August 20 at wind speed, 8.8 mph. The image is partially cloud obscured, showing enough of the bloom to catch the extent and concentration in key areas. Maumee Bay State Park continues to host a high concentration HAB from the shoreline to several nm into open water, 1 million to 2 million cells per 100 ml. Toledo, North Maumee Bay also 1 to 2 million cells, Metzer Marsh Wildlife Area, Catawba Island east side experiencing the higher concentration of the widespread HAB also. HAB concentration around the islands, including South Bass, Middle Bass and Kelleys bluegreen is less than 300 thousand cells per 100 ml. Sandusky Bay HAB appears broken up dispersed east and west of OH-269 at around 700 thousand cells per 100 ml. See the NCCOS images here.
