MICHELES Trenchless to Begin Trenching on Lake Hamilton for the Lake Ouachita Water Supply Project  


Hot Springs, AR - As Entergy starts the annual drawdown of Lake Hamilton this year (5 feet) on Monday, October 30th, MICHELS Trenchless Company, the City’s General Contractor for the Lake Ouachita Water Supply Project, will be installing lighted restricted work zone buoys across Upper Lake Hamilton.  This is in preparation for installing the 42” raw water transmission main across the lake bottom.  Boat travel on Lake Hamilton will be available upstream and downstream of the work zone, but navigation from the Highway 270 (Albert Pike) Bridge to Blakely Dam will not be possible. 


 MICHELS will start by placing turbidity (sediment curtains) across the lake from shore to shore at the work zone.  For shoreline preparation, clearing, and lake bottom preparation, large floating construction barges along with the MICHELS Marine Divers will require that no boat traffic be allowed to pass through the work zone on Lake Hamilton from October 30th to November 21st.  The restricted work zone is located under the Entergy Transmission Lines that cross the lake.  Workers will be on site in case of emergencies. A map of the work zone has been attached.
