Answers
Pennsylvania water level questions
Which Pennsylvania lakes show a live level here?
30 USGS lake gauges, listed in the live table.
Where do the Corps reservoir levels come from?
The Pittsburgh, Baltimore and Philadelphia districts of the Army Corps of Engineers publish pool elevations through CWMS.
How many Corps reservoirs are on this page?
10 Pittsburgh District, 11 Baltimore District and 5 Philadelphia District series.
Is the Lake Erie level shown?
Yes, from the NOAA station at Erie, in feet above IGLD 1985.
Why are Corps readings dated instead of live?
The site refreshes USGS values every hour; Corps and NOAA readings print as retrieved, with their date.
Why do some Baltimore District readings look small?
Those series use a local gauge datum, not sea level, so the number is a stage on that gauge.
Where are river flows?
Each river and stream page with a USGS gauge shows its own discharge and height.
Are tidal Delaware River stations included?
Yes, the NOAA tidal stations on the Delaware print their latest reading above MLLW.
