HYDROLOGIC INFORMATION

Notes:

1. These monthly duration curves were derived using average daily dam discharge observations recorded by the U.S. Army Corps of Engineers gage at the Chippewa Diversion Dam.

2. These flow duration curves are based on the best information available. These flow hydrographs represent the period 1970‐2019, and do not necessarily represent all possible future conditions. Questions may be addressed to the office of the Corps of Engineers St. Paul, Minnesota.

POOL ELEVATION DUR_1

CHIPPEWA DIVERSION

HYDROLOGIC INFORMATION

Notes:

1. These monthly elevation curves were derived using daily data collected from the U.S. Army Corps of Engineers Chippewa Diversion Pool Gage for the period 1970 through 2019. NGVD 29 + 0.56 ft = NAVD 88 at Lac qui Parle Dam.

The Project is just upstream of the diversion dam.

2. These elevation duration curves are based on the best information available. These elevation hydrographs represent the period 1970‐2019, and do not necessarily represent all possible future conditions. Questions may be addressed to the office of the Corps of Engineers St. Paul, Minnesota.

HYDROLOGIC INFORMATION

Notes:

1. The daily elevation hydrograph is based on ten years of average daily elevation observations recorded by the U.S.

Army Corps of Engineers Chippewa Diversion Pool Gage. NGVD 29 + 0.56 ft = NAVD 88 at Lac qui Parle Dam. The Project is just upstream of the diversion dam.

2. These hydrographs are based on the best information available. These 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.
