coastal stations are available from NOAA Center for
Operational Oceanographic Products and Services at

(see Figure 3-14 for an example of mean sea level trend
for a station in Atlantic City, NJ).

Great Lakes water-level records dating from 1860 are
maintained by the USACE Detroit District. The records
show seasonal water levels typically fluctuate between 1 and 2 feet. The records also show that long-term
(approximately 100 years) water levels in Lakes Michigan, Huron, Erie, and Ontario have fluctuated
approximately 6 feet, and water levels in Lake Superior have fluctuated approximately 4 feet. Figure 3-15
shows a typical plot of actual and projected lake levels for Lakes Michigan and Huron.
