About this file
This is a set of detailed engineering drawings and specifications for the Lock & Dam 7 Outdraft Modification project located in La Crescent, MN on the Mississippi River. The drawings, prepared by the US Army Corps of Engineers St. Paul District, include plans for modifying an existing weir and constructing new rock weir structures, with the primary components being a dog-leg weir, parallel weir, and launch rock structures with scour protection.
The drawings provide comprehensive technical details including site plans, cross sections, elevations, and control tables for construction. Key specifications show the dog-leg weir and parallel weir having a top elevation of 639.45 feet, with 30-inch and 45-inch scour protection at elevation 629.45 feet and 630.45 feet respectively. The project includes excavation and rock fill placement at specified slopes (typically 1V:3H and 1V:4H), staging areas on the Minnesota side of the lock, and marine access requirements. The drawings also contain detailed hydrological information including flow duration curves, daily flow hydrographs, and pool elevation data spanning 1949-2024 for Lock and Dam 7.

Notes:
1. The monthly flow duration curves were derived using the U.S. Army Corps of Engineers Lock and Dam 7 daily flow data for the period January 1959 through May 2024. The 1965 event (266,000 cfs peak) is the flood of record.
2. These flow duration curves are based on the best information available. These flow duration curves represent the period shown, and do not necessarily represent all possible future conditions. Questions may be addressed to the office

Notes:
1. The daily pool elevation hydrographs are based on data collected by the U.S. Army Corps of Engineers at Lock and Dam 7. There are 90 years of record (1934-2023). The highest recorded pool elevation occurred on April 21, 1965 (647.65 feet). MSL 1912 - 0.51 ft = NAVD 88 at Lock and Dam 7.
2. These daily pool elevation hydrographs are based on the best information available. These daily pool 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.

Notes:
1. These monthly duration curves were derived using the U.S. Army Corps of Engineers Lock and Dam 7 daily pool elevation data for the period January 1949 through May 2024. MSL 1912 - 0.51 ft = NAVD 88 at Lock and Dam 7. Note pool elevation data exists prior to 1949 but was not used to compute duration curves due to a change in operation that occurred in 1948.
2. These elevation duration curves are based on the best information available. These elevation duration curves represent the period 1949-2024, and do not necessarily represent all possible future conditions. Questions may be addressed to the office of the Corps of Engineers St. Paul, Minnesota.
