Water levels between Pointe Du Bois and Slave Falls will drop end of October until Spring

Posted on: October 11, 2018  |  

A 10-kilometre stretch of the Winnipeg River between the Pointe du Bois and Slave Falls generating stations will be lower-than-usual this fall and winter as Manitoba Hydro performs needed stabilization work on a spillway structure at Slave Falls.

About a one-metre (about three feet) draw down of the river behind Slave Falls will start about October 24th to reduce loading on one of the concrete piers in the station’s spillway.

Rehabilitation of the pier was already underway this summer when a detailed inspection found the concrete to be in worse shape than expected.

Reducing the water levels and stabilizing the spillway pier this winter will avoid further damage that could ultimately require much more extensive and disruptive repairs. The pier supports a spillway deck that is the only vehicle access to the Slave Falls Generating Station’s powerhouse. Further degradation could make access to the powerhouse difficult and impact regular operations and maintenance.

The water levels upstream of Pointe du Bois, including Lake of the Woods, will not be affected. Water levels changes downstream of Slave Falls will not change in any noticeable way.

The work is expected to cost approximately $2 million and be completed this winter. Water levels between Pointe du Bois and Slave Falls are expected to be restored to normal in the spring.

Slave Falls is one of Manitoba Hydro’s oldest generating stations. Construction began in 1928. The station was completed in 1948.

The work at Slave Falls is part of Manitoba Hydro’s commitment to continually upgrade aging parts of its electrical generation, transmission and distribution system with a focus on safety, reliability, and providing more capacity to meet the growing energy needs of our customers.

Manitoba Hydro released information this afternoon regarding the expected continued high water flows on the Winnipeg River. Water continues to rise significantly along the lakes that make up the Winnipeg River system (Nutimik, Dorothy, Margaret, Eleanor, and Sylvia Lakes as well as Pointe du Bois) as water moves downstream from Lake of the Woods. Water levels rise quickly in these areas due to natural restrictions along the river. Please see www.hydro.mb.ca/corporate/facilities/water_levels/ to view the forecast. Manitoba Hydro is predicating an increase of water levels from the current high water over the next 10 to 14 days, as follows: • 6 inches upstream of Eight Foot Falls. • 10 inches in Nutimik Lake. • 9 inches in Dorothy Lake. • 11 inches in Margaret/Eleanor Lake. • 1 foot in Sylvia Lake. • 8 inches upstream of Silver Falls. The Winnipeg River is expected to crest between June 5-10. Rising water levels and rapidly evolving conditions pose a significant risk to public safety. Manitoba Parks continue to monitor safety and water levels inside the closure area, additional safety measures may be applied if required. Manitoba Parks has been contacting all permanent residents in the closure area. If you have not been contacted by Manitoba Parks staff to register, please call the parks line at 204-340-6769 and leave a message with your name, lot, block, subdivision, and ask to be added to the permanent residents list. You will then be called back to register. Water levels improvement are being seen in all areas south of the Winnipeg River. Falcon, West Hawk, Star, Caddy, Brereton, White, and Jessica Lakes are reporting a decrease today. One log was also inserted into the West Hawk Dam on May 26 to slow the downstream flow, this change will take a few days to positively impact Jessica and White Lake. Manitoba Parks staff are working in conjunction with staff from the department of Manitoba, Transportation and Infrastructure to monitor lake levels and adjust control structures where possible. This includes monitoring structures for blockages. Crescent Beach seawall at West Hawk is barricaded and closed. Pay attention to signage, and barricades.
