Little Salmon River high flow at Bombay
Streamflow Situation from the USGS network of streamflow gauges in New York State
Little Salmon River is flowing in 99th percentile Thursday, the only site recorded in the NY Water Science network to signal an extreme high flow level. The streamflow monitoring site at Bombay in Franklin County is "rated", meaning that enough information has been recorded over a long enough term to enable comparisons. Normal flow for this location on this date are the measurements falling in the middle range of all flow measurements taken on this date over the time this location has been recorded, fifty-two years. Flood stage, the depth at which this channel is overwhelmed and begins to overflow has not been established. Little Ausable River is experiencing the highest August 22 flow value recorded in thirty years.

New York State blazes the trail in tracking of bluegreen algal blooms with a multi-agency approach to identifying suspicious algae, rapid response to confirm reports and effective platform for public notification. NY State Health Commissioner Dr. James McDonald statement in the kickoff statement for the 2024 HAB monitoring season was quoted, “Exposure to harmful algae blooms can cause health effects in people and animals, including pets, when water with blooms is touched, swallowed, or when airborne droplets are inhaled. New York State is aggressively proactive in monitoring and combating these blooms to protect public health, and this new map and reporting system will allow New Yorkers to better ‘Know it, Avoid it, and Report it.’".
From the NYS DEC notifications center, one hundred and thirty-two harmful algal blooms light up the active HAB dashboard Thursday morning, down from 135 yesterday. First confirmed HABs of the season have been confirmed in Brown's Lake and Onondaga Lake. See the impacted water bodies list here, updates are in progress as new reports are confirmed and added to the notifications board.
The last image of Lake Champlain HAB was snapped Aug 18 at unknown wind speed. In this capture we see slip of the widespread HAB in northeast Baie Missisquoi between clouds, the concentration rated high appears around 600 thousand cells per 100 ml. The last completely clear image was acquired August 14, the concentration range from 1 to 3 million cells per 100 ml. See our NY HAB report for more details here.
Lake Erie west basin
The latest satellite image of Lake Erie West basin was captured August 21 at wind speed, 16.1 mph, a clear image of the lakewide HAB in the west basin. The extent of the bloom has increased since the last fully clear image taken a week prior. The current image shows the HAB extends north of the international border.
HAB concentration is high, hot spots in Maumee Bay at Toledo 1 to 2 million cells, Maumee Bay State Park presents 1 to 3 million cells up to an including Cedar Point. Magee Marsh Wildlife Area another hot spot up to 2 million along the shoreline. The majority of the bloom is now running at extreme high concentration above a million cells per 100 ml. Sandusky Bay HAB is lakewide in the water west of OH-269 at around 700 thousand cells per 100 ml, the bluegreen occupying the water just east of OH-269 at the same concentration. See the NCCOS images here.
Louisiana: Lac des Allemands and Bayou Fortier have caught up with Lake Fields in the last twenty-four hours in terms of the extreme high concentrations developing in these water bodies over the last week. In this latest upload from the NCCOS dated August 21, taken at wind speed 11.5 mph, shows the hot spots 4 to 5 million cells now filling these water bodies from shore to shore. Lakes Verret and Palourde lakewide HABs also high concentration, 800 to 900 thousand cells per 100 ml. Check out the latest satellite image from NCCOS here.
