Ls Dennis Lindgren 2 is a privately owned earth dam located in Danbury, Iowa, along the Tr- Maple River. Constructed in 1995 by the USDA NRCS, this dam serves primarily for grade stabilization purposes and has a height of 35 feet and a length of 415 feet. With a storage capacity of 20 acre-feet and a drainage area of 0.11 square miles, the dam has a low hazard potential and a moderate risk assessment rating.

Managed and funded by the Natural Resources Conservation Service, Ls Dennis Lindgren 2 features an uncontrolled spillway with a width of 24 feet and outlet gates also uncontrolled. The dam has not undergone recent inspections and its condition assessment is not available. While the risk assessment is moderate, there are no emergency action plans in place and inundation maps have not been prepared. Despite these challenges, Ls Dennis Lindgren 2 remains an important structure for maintaining grade stability and protecting the surrounding area from potential flooding.
