HYDROLOGIC INFORMATION

Notes:

1. These elevation hydrographs were derived using the last ten years of daily stage data at the U.S. Army Corps of Engineers Lock and Dam 2. MSL 1912 ‐ 0.37FT = NAVD 88 at Lock and Dam 2..

2. These elevation hydrographs are based on the gage data at Lock and Dam 2 (Pool). These elevation hydrographs represent the period shown, and do not necessarily represent all possible future conditions. Questions may be addressed to the office of the Corps of Engineers St. Paul, Minnesota.
