Streamflow Situation from the USGS network of streamflow gauges
Cool and rainy upstate again today with a slight chance of thunderstorms tonight for NYC. Showers overnight have recovered the water levels in western rivers and streams, trending seasonal normal Sunday. Below normal to normal ratings persist through the Hudson River watersheds, an even mix of normal and below normal values recorded in the central drainage basin toward Long Island Sound.
Lake Ontario minor tributaries west remains in severe hydrologic drought mode impacting Niagara, Orleans and west Monroe Counties. A band of below normal rating area extends along the west border Lake Erie shoreline down to the Allegheny River watershed, also rated below normal. Interior Genesee River, Finger Lakes and south Chemung River watersheds are unrated. Below normal ratings pick up at Susquehanna River watershed, skip over Delaware River watershed (unrated) and pick up Ramapo River watershed below normal. In the northeast, Black River watershed remains below normal along with an adjacent piece of St. Lawrence River watershed around the Oswegatchie River channel. Mohawk and Upper Hudson River watersheds persist in below normal rating, along with adjacent Lake Champlain watershed. Lower Hudson River watershed is likewise rated below normal. As of this report, there are no extreme high or low flows recorded in the network.
Safe Drinking Water Advisories
Fulton County: Johnstown is under a BWA today after a water leak was detected Friday on County Route 131A. A loss of pressure in the water line can allow microbiological contamination, the BWA is a precautionary measure to ensure the safety of the water until the leak can be repaired and the potability of the water is established by lab testing. This BWA applies to customers connecting on County Route 131A, Lagrange Road, and Hulbert Road until further notice. Johnstown Waterworks serves a residential population 8154 from a surface water source in the Mohawk River watershed. The system is well run with no EPA violations in the last three years. The last sanitary inspection was done in July 2022.
