Telling Hudson River Stories with Graphs 2.
STORMS WATER LEVELS
2How might major storms impact water levels in the
Hudson estuary?
3Interpreting graphs What is the story that each
graph tells?
Answer these questions when looking at each
graph 1. What time period is shown in this
graph? 2. What is being measured in this
graph? 3. Where was the information gathered? 4.
What happens to it over the time period shown? 5.
What is your hypothesis about what caused this to
happen? 6. Measurements of what other parameters
would help you test and verify your hypothesis?
If you have Internet access, you can go to the
Hudson Environmental Conditions Observing System
website to check other parameters and test your
hypothesis.

9Tropical Storm Irenes one-two punch
Winds along the coast led to storm surge
flooding, showing as a water level peak in
Poughkeepsie and at the start of the flooding in
Albany.
Runoff from heavy rain caused flooding in the
watershed and at Albany. Runoff even affected
water levels at Poughkeepsie in the days
following the storm.
