With the recent warm temperatures, we have seen a significant decrease in the river basin's snowpack. The current snowpack is 2.95 MM of snow water equivalent, compared to the normal snowpack of between 0 and 57 MM for this time of year.

With the snowpack nearly melted, we are seeing the river flows stay consistent. The current flow rate is 31 Cubic Meters per Second, and normal flow rates are between 19 and 53 Cubic Meters per Second.

The forecast indicates some precipitation over the next seven days, with amounts between 20- 40 MM of rain; with this, we are expecting to see the river flows increase but remain within normal flow rates for this time of year. We are not, at this time, anticipating any advisories on river flows. The river forecasters and the Town’s Protective Services team will be monitoring.

The snowpack in our river basin is currently within the normal range for this time of year, measuring 108 mm of snow water equivalent. We are observing a slow melt of the snowpack.

At present, the river flow is below normal levels, measuring 21 cubic meters per second. Normal flows range between 25 and 65 cubic meters per second.

Minimal precipitation is forecasted for next week. We do not anticipate any significant changes in river flows. Temperatures are expected to rise throughout the week, leading to a consistent, slow melt of the snowpack.

The current snowpack in our river basin is below the normal range for this time of year. The current snowpack is 141 mm of snow water equivalent.

The current flow rate remains within expected flows and levels: 28.44 meters per second. Normal flows are between 25 and 65 cubic meters per second.

Minimal Precipitation is forecasted for next week. Later in the week, temperatures are expected to warm, resulting in a slow melt of the remaining snowpack.

The Towns Protective Services team has completed the annual flood prevention checklist and planning for the 2024 hazard season. Our crews will continue to monitor weather, snowpack, and river forecasting throughout the hazard season.

The current snowpack in our river basin is within the normal range for this time of year. We continue to see a slow melt of the snowpack. The current snowpack is 277 mm of snow water equivalent.

The current flow rate remains within normal flows and levels: 25.80 cubic meters per second. Normal flows are between 25 and 65 cubic meters per second.

A small amount of Precipitation is forecasted for next week; we are not expecting any significant changes in the river flows as a result. Later in the week, temperatures are expected to warm, resulting in a constant slow melt of the snowpack.

The current snowpack in our river basin is within the normal range for this time of year (between 300mm and 520mm). We continue to see a slow melt of the snowpack. The current snowpack is 342 mm of snow water equivalent.

The current flow rate remains within normal flows and levels: 29 cubic meters per second. Normal flows are between 25 and 65 cubic meters per second.

The weather forecast shows a warming trend with very little precipitation for next week. With the warmer weather, we may see an increase in the melt of the snowpack, which will result in increased river flows.

The current snowpack in our river basin is within the normal range for this time of year, between 300 mm and 520 mm of snowwater equivalent.

The current flow rate of the Highwood River is within the normal flow ranges for spring runoff conditions, which are between 19 and 46 cubic meters per second. The current flow rate is around 26 cubic meters per second.

Precipitation is forecasted for next week; however, we are not expecting any significant changes in the river flows as a result. Later in the week, temperatures are expected to warm, resulting in a slow melt of the snowpack.

"We use data provided by experts but we know the river, and the Town calls the shots to determine when action is required to protect our residents." -Craig Snodgrass, Mayor of High River

Local monitoring and observations are based on historical events, science and experience

• Spring thaw, Spring rains and snowmelt are predictable cycles of nature.
• History demonstrates that when these events combine, the effect on the Town is not predicable.
• The Town conducts an annual Hazard Risk Vulnerability Assessment to determine conditions each Spring.
• In 2022, the Town will reach a milestone with the completion of Flood Mitigation infrastructure to protect our community, making High River one of the most flood protected communities in Canada.
• River monitoring, weather patterns and scientific data from the Province provides the intelligence required for timely and informed decision making.
• High River is recognized as a World class leader in flood planning and response.
• Town staff monitor and interpret data provided to us in real time by the province. Trigger points are established indicating when control measures must be activated to protect our community.
• The Town uses this information to ensure the safety of the community and its residents.

For more information, view the Living on the the Highwood River document.

Many factors, both natural and human-induced, cause rivers to continuously change. The definitions used on High River’s River Monitoring signs are standard terminology used by hydrologists who study and measure stream flow.

• Each year, the town places LED signs in high-traffic areas to inform residents of the hazards during peak hazard season.
• These signs intend to raise awareness of the risk potential.

The Town will inform residents if action is required based on the risk. Refer to Town information on the website and social media and listen for alerts.

The Town uses the provincial standard to monitor the river:

• Normal
• High Stream Flow Advisory
• Flood Watch
• Flood Warning

Action is not required until the Flood Watch stage, but it is always good to be prepared for an emergency.

To help understand the reported flow rates, please note that the river flow during the 2013 flood reached 1820 cubic meters / second.

Normal Flow Stage

Flow is measured by noting the amount of water passing by monitoring stations. This data is available in real-time for the critical stations monitored by Town staff on rivers.alberta.ca.

High Stream Flow Advisory Stage

Stream levels are rising rapidly, and no major flooding is expected. Minor flooding in low-lying areas is possible. Anyone close to the streams affected is advised to be cautious of the rising levels.

It is always important to be prepared if the stream flow advisory becomes a Flood Watch. Water volume and flow are ever-changing, and the advisory may be cancelled when flows return to normal. If volume and flow return to normal, this stage will be followed with the normal stage, or the advisory will be lifted.

Flood Watch Stage

Stream levels are rising and will approach or may overflow the riverbanks. Flooding of areas adjacent to these streams may occur. Anyone situated close to the river is advised to take appropriate precautionary measures.

Flood Warning Stage

Rising stream levels will result in flooding areas adjacent to the affected streams. Anyone near the river should take appropriate measures to avoid flood damage and injury.

Pay attention to Town information on the website and social media and listen for advice on actions required to protect yourself, your family, your pets and your home.

Town Monitoring Snowpack Melt Closely – No Concerns at Present

Alberta Environment and Parks has many river monitoring stations on their Rivers Alberta website. The Town focuses on those set up for the Highwood River Basin.

The stations monitored by the Town of High River are chosen because they provide the most relevant and timely data regarding the volume and flow as the river approaches the Town.

Data available includes daily real time information about:

• Snowpack and snowmelt information predicted by teams of experts who set stations up in the mountains at the river’s source
• Stream flow and volume as it passes by these stations

Staff also monitor temperatures and precipitation to anticipate potential impacts on the stream volume and flow. This monitoring data is available publicly and is shared with residents. High River staff monitor the river until the end of June.

Key Monitoring Stations: Highwood River

• Stimpson Creek near Pekisko
• Highwood River at Diebel’s Ranch
• Trap Creek near Longview
• Pekisko Creek new Longview
• Highwood Diversion Canal near the Headgates
• High River Below Little Bow Canal
