Terrebonne Parish BWA
Safe Drinking Water Advisories
Terrebonne Parish: A BWA was issued yesterday for customers along Hwy 56 from 7719 Hwy 56 to the end of the road, including Red Fish St and Waterfront Dr and Coco Marina, until further notice.
Streamflow Situation from the network of USGS streamflow gauges in the USA
Six monitoring stations are noted above flood stage Tuesday afternoon, most located in Florida. Louisiana streamflows have dropped lower in the east with most stations recording below normal to low. The west side of the state has normal streamflows, the central and northeast running below seasonal normal to much below normal. Region 3 watershed has popped up with a below normal along the Arkansas border, Region 7 remains in below normal status with Tangipahoa Parish in extreme drought.

Louisiana: The latest image of Lake Pontchartrain and southeast Louisiana water bodies captured August 26 at high wind, 13.7 mph, mostly cloud obscured. Lakes Pontchartrain and Maurepas are visible in this picture with no HAB activity observed. The prior image Aug 25, taken at the higher wind speed over 15 mph is also quite obscured, a small area of the Bayou Fortier bluegreen shows up with extreme high concentration 3 million cells per ml, Lac des Allemands HAB appears lower concentration, 700 to 800 thousand cells. Lake Fields is cloud obscured in this image. Lake Verret is cloud obscured, Lake Palourde and the water to the south show 900 thousand to 1 million cells per ml lakewide blooms.
Georgia
Cyanobacteria cell counts are in for locations in Lake Burton and Lake Harding with other locations pending as we gather the information from Cyanobacteria Assessment Network. Lake Burton HABs over 500 thousand cells per ml in an estimate from April 20, 2024 was an elevated cell count from the prior reading in December 2023. Lake Harding Phipps Island count taken July 27 estimated lower than the prior count in July, just above 100 thousand cells per 100 ml.
New York
The NYS Department of Environmental Conservation HAB notifications dashboard more than doubled this morning as confirmed HABs reports broke from 109 to 241, smashing the daily record set earlier this month. The majority of new reports today coming in from the Finger Lakes. HABs reported prior to August 14 have been removed to the archives, 600 HABs have come and gone during the 2024 season. The latest impacted water body list is available here, updates are in progress.
A nice clear shot of Lake Champlain provided by the NCCOS August 26 shows the northeast HAB has jumped up in concentration along the north shoreline, the prior image showed a small hot spot matching the concentration color scale for 2 million cells, this latest image shows that hot spot has increased in area along the north shore, now matching a concentration of 3 or 4 million cells. Two more hot spots have formed in this lakewide bloom south of Baie Missisquoi in the channel near Alburg-Swanton bridge, and down near the north end of North Hero Island, up to 2 million cells in each of those hot spots. The majority of the bloom matches 900 thousand to 1 million cells per ml. See the NCCOS color images, here.
Lake Erie west basin
A nice clear image snapped by NCCOS partner satellite shows the Lake Erie HAB with the appearance of a bluegreen goose! The neck and head reach up into Canadian water the beak approximately 8 nm of shore south of Leamington. The tail touches Stony Point north of Monroe, concentration of the head, neck, back and tail running around the 300 thousand cells concentration. The belly of the goose is 1 million cells per ml, lays right up against the Ohio shoreline from the east side of Cedar Point National Wildlife Refuge along Reno Beach to Magee Marsh Wildlife area. The orange feet of the goose are planted in Maumee May at Toledo and Maumee Bay State Park, appearing to match matching the color scale for concentration 2 to 4 million cells. See the bluegreen goose here.
The narrow band of HAB spotted in the August 25 capture is again seen along shore past Camp Perry to Port Clinton. Bluegreen remains in the east side marinas of Catawba Island, dispersed HABs north and east from Kelleys Island occupy an area of the Canadian water running a moderate concentration below 200 thousand cells per ml. Sandusky Bay Aphanizomenon HAB has moved out of the inner bay water and bunched up east of OH-269 bridge, the concentration matches color scale for 600 thousand cells per ml.
