Seasonal High Water Monitoring

Update: 11:00 a.m. Monday, June 26, 2017

The Bow River level is within normal range and is expected to stay within range for the foreseeable future. High groundwater levels are still expected throughout valley bottom, however, several areas are not as affected as the previous weeks.

The Bow River is rising slightly due to the very warm weather, however there is not a lot snow remaining so high levels on the Bow River are not expected. While a small storm is forecasted this week, the minimal precipitation should not be enough to affect the Bow River and the creeks. Up to 10mm over four days is expected. Lake Minnewanka and the Spray Reservoir are within normal ranges.

Unless a large storm is forecasted to impact the Bow Valley, this will be the last seasonal high water monitoring report for this year.

Previous Updates

Update: 10:30 a.m. Monday, June 19, 2017

The Bow River level is back within normal range and is expected to stay within range for the short-term. While the ground is still saturated, high groundwater levels continue throughout valley bottom, although several areas are not as affected as in previous weeks.

Minimal precipitation is forecasted for the Bow Valley, and with the cooler temperatures and the small amount of snow left in the watersheds, it will not be enough to affect the Bow River and the creeks.

The pathways underneath the Bow River Bridge, and the golf course culvert remain closed. Lake Minnewanka and the Spray Reservoir are both back within normal range.

 

Update: 9:30 a.m. Friday, June 16, 2017

The Bow River water level is slightly higher than normal after the precipitation of previous couple of days, but is currently not a cause of concern. However, the ground is saturated with water and capacity for infiltration is low. High groundwater levels are still expected throughout valley bottom.

Unstable conditions are expected for the weekend with shower activity and thunderstorms. However, only up to 5mm of precipitation is forecasted. This precipitation should not affect the Bow River and the creeks.

The Spray Reservoir is within normal range, and Lake Minnewanka is slightly above seasonal, but there are no concerns from TransAlta.

 

Update: 6:30 p.m. Tuesday, June 13, 2017

We are expecting significant rainfall tonight, resulting in more ponding on our streets and in low lying areas. Since the valley bottom is already saturated with high groundwater, capacity for infiltration is low. Groundwater issues may become worse for several properties.

Update: 12:00 p.m. Monday, June 12, 2017

The Bow River water level is within seasonal normal ranges and it is dropping after peaking on Saturday, June 10, so is currently not a cause of concern. However, high groundwater levels continue throughout valley bottom as the ground is saturated with water and capacity for infiltration is low.

A new storm is forecasted to affect the Bow Valley on Tuesday until Wednesday, with up to 15mm of precipitation is currently forecasted. While this storm is not anticipated to greatly affect the Bow River, the creeks may start to flow again due to the precipitation. As well, at higher elevations, ~20cm of new snow fell on Saturday, and it will melt quickly.

Update: 5:00 p.m. Thursday, June 8, 2017

While a large storm is tracking nearby, it is not forecast to have a big effect in our area. There are likely to be scattered showers over the weekend, and nearby creeks might flow again due to the forecasted precipitation. The Bow River level is above seasonal normal, after peaking on Friday, June 2, and is not currently a cause for concern. However, high groundwater levels are expected throughout valley bottom.

The pathway underneath Bow River Bridge and the golf course culvert remain closed. Lake Minnewanka is slightly above seasonal, and the Spray Reservoir is within normal range.

Update: 9:30 a.m. Monday, June 5, 2017

The Bow River peaked on Friday, June 2, but has been steadily reducing since then. While levels are currently above seasonal normal, it is not currently a cause of concern. However, there are some concerns with high groundwater levels that are expected throughout valley bottom.

Snowmelt in the Bow River watersheds has slowed down. Creeks are not expected to flow as much as the last few weeks due to cooler ...temperatures and the diminishing snow pack. However, increased flow may start with warmer temperatures forecasted for later this week, especially in the afternoons.

The pathway underneath Bow River Bridge and the golf course culvert remain closed. Lake Minnewanka is slightly above seasonal, and the Spray Reservoir is within normal range.

On June 1, Alberta Environment and Parks issued a High Streamflow Advisory for the Bow River and its tributaries upstream of the Town of Cochrane.

 

Update: 11:30 a.m. Friday, June 2, 2017

As forecasted, the river is higher again today. In some places, the water is getting very close to flowing along some sections of our pathways along the Bow River that are located below the dike. Watch for signage in case pathways need be closed over the next few days. Please use extreme caution around creeks and river banks.

While there are some concerns that the Bow River is higher than usual for this time of year, water levels are still below 2013 levels, and below the threshold for the capacity of the dike system along the Bow River.

Snowmelt will continue to contribute to higher flows, and high groundwater levels throughout valley bottom are affecting some residential and commercial buildings.

Update: 10:00 a.m. June 1, 2017

While there are now some concerns that the Bow River is higher than usual for this time of year, water levels are still well below 2013 levels.

Snowmelt will continue to contribute to higher flows, and the Bow River is expected to reach 300cms in the next 48 hours. Therefore, we will start monitoring the banks more closely. The creeks have had significant flows in the last few days, especially in late afternoons. Please use extreme caution around creeks and river banks.

The high groundwater levels throughout valley bottom are affecting some residential and commercial buildings. Groundwater levels are expected to rise with higher flows on the Bow.

Pathway underneath Bow River Bridge closed, and Golf Course Culvert closed.

Lake Minnewanka is slightly above seasonal, and the Spray Reservoir is within normal range.

 

Update: 10:00 a.m. May 29, 2017
There are NO current concerns.

Flows are on the high side of the normal range for the end of May. Warm temperatures are rapidly melting snow in the Bow Valley watersheds. For the next several days, expect creeks to flow and the flow of the Bow to increase.

Update: 10:00 a.m. May 25, 2017
There are NO current concerns
Flows are on the high side of the normal range for the end of May. Cooler temperatures today will keep snow melt to a minimum. The large storm is mostly over and precipitation should stop today. Nicer and warmer weather will resume snow melt in the next several days.
Precipitation of last 36 hours should start making its way to the Bow and the creeks, especially with warmer temperatures. For the next several days, expect creeks to flow and the Bow to stay around current levels.
Levels at Lake Minnewanka are slightly above seasonal, and the Spray Reservoir is within normal range.
Cougar Creek debris net has been inspected and the door has been closed.
Other creeks are expected to flow due to high amount of precipitation over last 36 hours. The new snow will start melting and contribute to flows starting on Friday and should continue over the weekend.

 

Update: 5:00 p.m. Wednesday, May 24, 2017
There are NO current concerns.
Bow River flows are high but still within normal ranges for the end of May. Cooler temperatures in next 48 hours will reduce snow melt. The current precipitation has been factored into the forecasted increase of the Bow River, Cougar Creek, and other nearby creek flows. The Bow River flows are expected to stay around or above current levels for the next week. The creeks around... Canmore can also flow with warmer temperatures or heavy precipitation.
As is normal for this time of year, the gates have been closed to the pathways under the Bow River bridge.
We will keep you updated as we receive more information.
