The Crooked River Lock in Alanson, Michigan will open today, April 29, for the 2024 recreational boating season after undergoing a series of repairs during the offseason. 

“Since the Crooked River Lock closed for the season the U.S. Army Corps of Engineers, Soo Project Office, Maintenance team replaced, programmed and tested faulty safety modules and a Variable Frequency Drive (VFD), which is a type of motor controlling speed and torque,” said LeighAnn Ryckeghem, Soo Project Office Operations Manager. “Water level sensors have also been replaced and calibrated and are fully functional for reporting hourly water level data. All pre-inspections and machinery greasing have also been completed to open the lock on time.”

Electrical issues related to the faulty safety modules forced the lock to close early in  fall 2023 and undergo repairs to its aging components. 

The Corps of Engineers originally built the clamshell-style lock in the mid-1950s to maintain the water levels in Pickerel Lake and Crooked Lake. It remains owned by the Corps of Engineers but leased to the Michigan Department of Natural Resources (MDNR). Emmet County, under a sublease with the MDNR, to operate and staff the lock during the spring to fall boating season.  

About 10,000 lockages are performed at the lock each year on the recreationally popular, 40-mile Inland Waterway. The route connects Lake Huron with five lakes and three rivers inland into Michigan’s Lower Peninsula.  

In 2020, it was the third busiest Corps of Engineers recreational lock.  

The U.S. Army Corps of Engineers, Detroit District, maintains a navigation system of 81 harbors and channels joining lakes Superior, Michigan, Huron, St. Clair and Erie.   

The Detroit District provides vital public engineering services in peace and war to secure our Nation, protect the environment, energize our economy and reduce risks from natural disasters.
