Throughout winter, the Snow/Maintenance Foreman assesses the ice conditions once a week in the designated skating areas at Henderson Lake, Nicholas Sheran Lake and Chinook Lake using the following criteria:
- The presence of standing water or open water
- The amount of freezing that has occurred
- Snow cover
- Present thickness of the ice
- Present condition of the ice
- Present clarity of the ice
- Air temperature
Once an assessment has been made from the information gathered, the Snow/Maintenance Foreman will share the information and declare if the lake ice meets the standards for public use. This information is shared in the News Centre, on our website as well as on Facebook and Twitter.
Because the ice is not always clear blue, calculations for ice thickness is done by this formula:
TOTAL CLEAR ICE + 1/2 TOTAL WHITE ICE = TOTAL MEASUREMENT
Here are the current ice conditions for the designated skating areas at Chinook, Henderson and Nicholas Sheran Lakes. Please note, ice measurements will NOT be taken if there is open water on the lake.

Lake Ice in Lethbridge
The condition, strength and stability of ice can change dramatically depending on temperature, precipitation, wind and the amount of sunshine.
Unique weather variables such as frequent Chinook winds that can see air temperature going above freezing for six hours over a 24 hour period can cause ice to lose strength and stability.
Chinook winds bring warmer temperatures that can quickly affect the melting rate for ice along the shore and near bridges which can lead to open water. As well, following a Chinook, a rapid, large temperature drop can make ice brittle.
Storm Ponds
Storm pond water/ice contact is prohibited. Ice on storm ponds is not monitored by the City.
It is dangerous to walk, play or skate on any ice surface that has areas of open water. Water entering storm ponds can contain impurities and is warmer in temperature, which can contribute to unstable and unpredictable ice conditions. Water levels in storm ponds can fluctuate, increasing the odds of air pockets. Please stay off storm ponds at all times.
Ice Fishing
Ice fishing is not permitted in designated skating areas.
Ice Safety
If you see someone fall through the ice call 911 immediately.
