Report on: Water management issues in the Whiteshell Provincial Park
Report to: WCA membership
Report by: Alan Roberts, P.Eng. – Director – Whiteshell Cottagers Association; and
Chair: Lake Water Levels Committee

Run-off of the heavy November precipitation into the primary collector lakes and rivers is largely completed, and is now on route to the Winnipeg River and Shoal Lake. Many of the downstream collector lakes from White Lake to the Winnipeg River, continue to be very high compared to their drawdown target levels. The drawdown has continued apace through the winter due to the relatively mild temperatures we’ve experienced this year, and we expect the target level to be achieved prior to spring break-up in most cases.

We continue to press for upgrading of the level monitoring equipment in the Whiteshell lakes, with little success thus far. Though the manual monitoring stations have been refurbished, numerous stations go unmonitored. Also, we continue to press for tapered flow control weirs that can retard the rate of discharge through the summer, rather than flat weirs which only establish the minimum level. The level of Falcon Lake is not known, however the Falcon River is now below the lake level, and the rate of drawdown is limited only by the decrepit control structure. The lack of topographic relief along the Falcon River combined with the heavy November rains, prevented the drawdown occurring until mid- January.

The snow pack is relatively light with much of this winter’s precipitation having come early – as rain instead of snow, and has entered the collection lakes along the Whiteshell River already. Though the soils are near saturation from the November rain, above normal spring run-off is not expected to occur without heavy snow fall over the next month or so, or heavy spring rains. A Functional Planning Study for replacement of the water level control structure at Falcon Lake has been initiated by MIT, and we hope to see a new facility in place within 18 months. Use of a conventional control structure will require dredging of the Falcon River (if there is enough topographic relief to provide adequate flow) which may not be permited by Environment Canada. Mechanical solutions that can raise the elevation of the Falcon River without requiring an Environmental Review are preferred over the purely gravity flow options.

Star Lake has abnormally high water level due to the November rains combined with beaver blocking the discharge culvert. The water is at 1115.75 ft. – about one foot higher than it should be and will only get worse if Parks is not able to remove the blockage before spring runoff. Parks has been asked to install beaver protection for the discharge culvert once flow is restored.

Hello WCA, Here are the new items for today. - Manitoba Hydro released information this afternoon regarding the expected continued high water flows on the Winnipeg River (we have provided the link below and some of the key lake points). The Winnipeg River is expected to crest between June 5-10. Please see www.hydro.mb.ca/corporate/facilities/water_levels/ to view the forecast.- The shoreline adjacent to the Pointe du Bois subdivision has been included in the 100 metre from shore prohibition on recreational motor boat use. Whiteshell Provincial Park: May 27, 2022 A local state of emergency has been declared for Whiteshell Provincial Park on May 20, 2022 due to rising water levels within the park. Developed areas at Betula Lake were closed on May 21, 2022. This closure area was expanded (May 24) to include Sylvia Lake, Otter Falls, Dorothy Lake, Barrier Bay and Nutimik Lake areas. No person should reside or enter into the closed area. Please visit the Manitoba Parks Website www.gov.mb.ca/sd/parks/ to see a map of the closure. This applies to all cottage subdivisions, commercial areas, campgrounds, group use, day use, recreational and picnic areas, playgrounds, trails, and beaches with within the order area. During the closure no person should reside or enter into the closure area of the park. 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. The travel lane has been moved away from the wall and is narrow in spots, please travel slowly. Cottages in the Crescent Beach, High Rock, McKenzie Beach, and Hunt Lake subdivisions should be aware of the potential for a re-route in the event of further damage to the seawall. Sandbags for filling and sand are available for cottage owners at: the 8 Foot Falls Road in Pointe du Bois, Jessica Lake at the garbage collection site, the parking lot across from Brereton Lake Resort, the West Hawk maintenance yard, and the causeway at Falcon Lake. There are a limited number of pre-filled bags at the Jessica Lake and Pointe du Bois depots. PR 307 from the west park entrance to the PR307/309 junction, and PR 312 near Caddy Lake is closed to all traffic. PR 309 near Meditation Lake is restricted to local traffic only. We encourage everyone to check manitoba511.ca before travelling. You can call 511 anywhere in Manitoba to get updates by phone. Water is present on several block roads throughout the park. White Lake Block 4 is closed to vehicle use. The following block roads should not be crossed in a smaller vehicle until the water recedes: High Rock Road at West Hawk, and Jessica Lake Block 5-6-7-8. Caution should be used when travelling through flooded areas. The following boat launches are closed in addition to those in the park closure area: 8 Foot Falls, Big Creek, White Lake, Jessica Lake, South Shore Big Whiteshell, and Toniata. West Hawk and Falcon Beach Campground Boat launches have been re-opened. Public can expect open launches to be without docks, high water is preventing repair and placement of docks throughout the park. Please use caution and courtesy when boating. All boat traffic should be cautious of debris and items submerged below the surface. Please be advised that you cannot visit the closed area of the park by boat. Access is not allowed to your cottage or recreational areas via the Winnipeg River. No landing in the closed area is allowed. Extreme caution should be used with travelling the upstream portion of the Winnipeg River (Pointe du Bois to Lamprey Falls). To minimize potential erosion caused by boat wakes, recreational motor boat restrictions are in place. Recreational motor boat traffic is prohibited from operating within 100 metres of the shoreline on: West Hawk, Falcon, Caddy, Star, Brereton, Jessica, White, Big Whiteshell, Betula, Nutimik, Dorothy, Margaret, Eleanor Lakes, and the shoreline adjacent to the Pointe du Bois subdivision in Whiteshell Provincial Park. When exiting or approaching the shoreline, boats should move directly out from land and avoid creating a wake. The following hiking trails are closed in addition to those in the park closure area: the Marsh Trail (between Falcon Lake Marina and Beach Campground), TransCanada Trail at Penniac Bay, and Hunt Lake. All backcountry campsites in Whiteshell Provincial park are closed due to flooding, high water conditions and frequently changing portage conditions. Campers should check the Manitoba Parks homepage for the status of campgrounds prior to coming to the park. Several campgrounds have full or partial closures. All campground in the closure area will remain closed until this portion of the park reopens (Dorothy Lake, Opapiskaw, Nutimik Lake, and Otter Falls). In addition, White Lake Campground is closed (seasonal and nightly) and nightly camping is closed in Big Whiteshell Campground.
