On this date in water recording history, record high flows on Raquette, Saranac, Independence, Sacandaga and Chenango Rivers
Streamflow Situation from the USGS network of streamflow gauges in New York State
The current streamflow dashboard for NYS remains in the abundance end of the scale midweek with record high flows recorded again today. In the last 68 years of recording the water level in Raquette River at Raymondville, the volume and depth has never been greater than it is today. This record high scenario is played out all over the north: Saranac, Independence and Sacandaga Rivers all at record highs today, Little Chazy, Oswegatchie, St Regis, Salmon, Little Salmon and Beaver Rivers on to a consecutive day of record high flow. Cold Spring Brook in Long Island weighs in heavier today than at any August 21 in 72 years of measuring. Record high streamflows for this date in water recording history again apply to Sandy Creek, East Branch Fish Creek. NWS has no weather hazards for New York today.
WT HAB Tracker
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.
from the satellite monitoring program of the NOAA National Centers for Coastal Ocean Science(NCCOS) and State sources where available
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.
Lake Erie west basin
Algal toxin advisories remain for two Lake Erie State Park beaches today, Maumee Bay State Park second such advisory of the season posted a month to the day after the first advisory. The HAB in this location has been parked and cooking up a high concentration, 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.
Louisiana: The latest upload from the NCCOS is dated August 20, taken at wind speed 8.3 mph is a clear capture showing a clear Lake Pontchartrain and a very high concentration spreading through Bayou Fortier and Lac des Allemands. Hotspots continue to expand, 1 to 4 millon cells per 100 ml lakewide, the highest concentration found in the east half of Bayou Fortier. Lake Fields is completely socked in with HABs 3 to 4 million cells. Lakes Verret and Palourde chug along at a consistent 700-800 thousand cells per 100 ml, lakewide.
