Low flows in the northwest keep Lake Ontario watershed in extreme drought
Streamflow Situation from the monitoring network of USGS in New York
Low flow levels in the Lake Ontario minor tributaries west watershed have collapsed the area of Niagara, Orleans and west Monroe Counties into an extreme hydrologic drought condition continuing midweek. Northrup Creek runs a 2nd percentile low flow several days now, Allen Creek at Rochester runs a record low for a second day in a row, these are the lowest October 2 levels measured in 64 years. Elsewhere in New York, the west interior will likely see showers today, a 60% chance according to NWS Binghamton. Another low is recorded midweek in the Ramapo River watershed, this basin has its top end in Orange and Rockland Counties, moving water from the Ramapo mountains down through New Jersey and out to the Atlantic via Chesapeake Bay.
No hazardous weather in the forecast for NYS Wednesday, no active flooding in the monitored network, no extreme high flows, one extreme low recorded a second day running in the lower Genesee River watershed.

Two hundred and thirty HABs are active on the notifications board midweek, up from 216 yesterday morning. New to the impacted water bodies list this season, Meacham Lake in Franklin County, Hope Lake in Cortland, Lake Moraine in Madison County and Mountain Lake in Sullivan County all debut on the HAB notifications board Wednesday. Van Cleef Lake and Lower Saranac Lake are back on the actively impacted list, new bluegreen activity confirmed yesterday by DEC staff. The Lake in Central Park is back on the active list, along with Turtle Lake and Harlem Meer in Central Park. A batch of new reports was confirmed in Seneca Lake after the big lake dropped half of its algal blooms this week. Updates are in progress, the latest impacted water body list is available here.
The latest satellite image of Lake Champlain was captured October 1, this image is partially cloud obscured with no HAB activity evident. A prior image Sept 29 shows Baie Missisquoi with open water HABs of a low concentration, 100 thousand cells per ml. A new area of HAB activity revealed in the channel between Point Au Roche and North Hero Island, low concentration 100 thousand cells per ml or less. Lake Carmi in Vermont presented lakewide HAB of high concentration, 900 thousand cells per ml.
