About this file
The provided document is a soil investigation report for the Noyes Levee Repair project located in Noyes, Minnesota. The report contains detailed soil testing and geological analysis from two test pits (Test Pit 1 and Test Pit 2) conducted on May 15, 2024, by the US Army Corps of Engineers St. Paul District. Both test pits revealed similar soil compositions: a thin layer of black topsoil followed by a brown, brittle clay with silt (classified as Fat Clay or CH), extending to a depth of 15 feet.
The soil laboratory analysis provides critical geotechnical data for the levee repair project. Test Pit 1 and Test Pit 2 soil samples showed nearly identical characteristics: approximately 97-98% fine soils, with liquid limits around 50-51, plasticity indexes of 30-31, and moisture contents of 34-35%. The moisture density curves indicate a maximum dry density of 94.0-94.9 pounds per cubic foot, with an optimum water content of 26.0%. Notably, Test Pit 2 recorded water infiltration at 12 feet deep, which may be an important consideration for levee reconstruction and drainage planning.
