Flood Risk Management Project, Lander, WY

Project Name: Popo Agie Flood Risk Management Study
Location: Lander, Wyoming
Authority: Section 205 of the Flood Control Act of 1948, as amended
Sponsor: City of Lander
Current Phase: Feasibility

The city of Lander (non-federal sponsor) is partnering with the U.S. Army Corps of Engineers (Omaha District) on a study to evaluate possible flood risk management solutions along the Popo Agie River and Dickinson Creek in Lander, Wyoming.

The city of Lander has experienced frequent flooding since the late 1800s with the most recent event on June 5, 2010. Mountain snowpack melted quicker than usual due to a sudden warm-up, which was compounded by rain. As a result, the Popo Agie River flooded in Lander. The Corps assisted with flood fight efforts by providing emergency management resources and construction of flood protection measures. While flooding caused damages and resulted in significant emergency expenditures at various levels of government, the river did not reach record levels.

The purpose of the Popo Agie feasibility study is to identify the potential for developing flood risk management solutions, which could be structural and nonstructural, that are beneficial to the public, economically viable, and environmentally acceptable.

Project Update: The U.S. Army Corps of Engineers and City of Lander held a virtual public meeting on Thursday, April 9, 2020 at 6:00p.m. (Mountain Time) to gather input on the recommended flood risk management plan for the Middle Popo Agie River. Comments on the project and draft feasibility report can be mailed to: U.S. Army Corps of Engineers Omaha District, Attn: CENWO-PMA-A (Rachel Shrader), 1616 Capitol Avenue, Omaha, NE 68102. Comments can also be emailed to cenwo-planning@usace.army.mil. Comments must be postmarked or received by May 2, 2020.
