Moderate drought rating dropped from the east side of Colorado River watershed
Streamflow Situation from the network of USGS streamflow gauges in the USA
Four sites in the reference network record flows above minor flood stage midweek, three in Florida and one in South Carolina. California streamflows run at seasonal normal levels in the interior watersheds Region 5 and 6, still running below normal in the south, and above normal to much above normal through the coastal watersheds Region 1, 2, 3, 4, 8 and 9. San Bernardino County has shaken off the moderate drought rating overnight, leaving the west half of Colorado River watershed rated below normal. A small area is rated below normal in the north end of Region 5 Central Valley watershed.

California
The freshwater Recent HAB Bloom Update came out Friday August 23 with one HAB DANGER-level advisory applied to Lindo Lake in San Diego County. This advisory for algal toxin states toxins in this water can harm people and kill fish. The posted signage specifies cautions including no swimming, no wading, no consuming of fish or shellfish caught in these waters. Three HAB Warning advisories have been issued for Weist Lake, Crowley Lake Marina and Guajome Lake. The HAB warning advisory carries the same caption as the danger advisory, with the exception that fish fillets cleaned with tap water or bottled water and properly cooked can be consumed. This water is still not considered safe for wading or swimming, and shellfish should not be consumed. Note that water containing HABs likely also contains toxins, the water cannot be made safe for consumption by boiling.
Georgia
Cyanobacteria cell counts are in for locations in Ocean Pond, Lake Blackshear, Walter F George Reservoir and more. Lake Burton has the highest cell count so far, over 500 thousand cells per ml in an estimate from April 20, 2024. Next is Alexanders Landing in Walter F George Reservoir, measured around 125 thousand cells per ml in early June this year. More to follow as we work through the Cyanobacterial Assessment Network (CyAN) collected data for the major water bodies in Georgia.
New York
The HAB notifications dashboard more than doubled yesterday with the addition of 132 new bluegreen reports confirmed all over the state. HABs reported prior to August 15 have been removed to the archives, 609 HABs retired 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 27 shows the northeast water with a high concentration bloom along the north shoreline, the concentration appears a match for 3 million cells per ml. Lake Carmi is full of the bluegreen algae at the 900 thousand to 1 million cells per ml concentration. Water east of Shelburne Bay, likely Shelburne Pond, lakewide HAB 3 million cells. The Lake Champlain image is cloud obscured south of Baie Missisquoi, a prior image captured Aug 26 showed hot spots in the channel near Alburg-Swanton bridge, another at the north end of North Hero Island, up to 2 million cells per ml. The majority of the bloom matches 900 thousand to 1 million cells per 100 ml. See the NCCOS color images, here.
Lake Erie west basin
A clear image from NCCOS August 26 shows the Lake Erie HAB has taken on the shape of a 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, theconcentration of the head, neck, back and tail running around the 300 thousand cells concentration. The belly is 1 million cells per ml along 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 the color scale at 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.
Louisiana: The latest image of Lake Pontchartrain and southeast Louisiana water bodies captured August 27 at an estimated wind speed 11.7 mph. This image is mostly clear, showing Lakes Pontchartrain and Maurepas with no HAB activity evident. Bayou Fortier and Lac des Allemands lakewide HABs 2 to 3 million cells, Bayou des Deux Chenes 900 thousand to 1 million cells. Lake Fields lakewide HAB is 1 to 2 million cells per ml. Lakes Verret and Palourde are cloud obscured, the prior image showed lakewide HABs 900 thousand to 1 million cells per 100 ml lakewide blooms.
