the hidden dangers of storm pond skating

Winter brings a season of ice and snow, transforming the landscape into a scene of beauty and recreation. Outdoor skating is a cherished activity for many, but not all frozen surfaces are safe. Storm ponds, despite their inviting appearance, present significant risks and should never be used for skating.

understanding the risks of storm ponds

Storm ponds are engineered basins designed to manage stormwater runoff in urban areas. Their primary purpose is to collect rain and melted snow, reduce flooding, and improve water quality by allowing sediments and pollutants to settle. While they play a vital role in city infrastructure, their design and function make them unsuitable for recreational activities.

key winter dangers of storm ponds:

Below are some of the hidden dangers of storm ponds that make them unsuitable for skating:

• Inconsistent Ice Thickness: water levels in storm ponds fluctuate, resulting in uneven ice thickness. A seemingly solid surface can mask dangerously thin areas, increasing the risk of accidents.

• Unpredictable Water Flow: storm ponds have active drainage systems, with water continuously flowing in and out. This movement weakens the ice from below, compromising its stability.

• Contaminants in the Water: stormwater runoff introduces pollutants, such as chemicals, oil, and debris, into these ponds. These contaminants lower the freezing point of water and further destabilize the ice. Falling through the ice could expose individuals to harmful substances.

• Unstable Ice Conditions: fluctuating water levels often create air gaps between the ice and water, resulting in fragile and unpredictable ice surfaces. This makes storm ponds particularly hazardous for skating.

• Steep Slopes and Drop-offs: the edges of storm ponds are often steep, with sudden drop-offs that increase the risk of falls and other accidents near the water’s edge.

how to identify a storm pond?

All storm ponds have identification signage around them usually indicating that they are a stormwater management facility and advising which activities to avoid in and around them. Below is a typical storm pond sign within the City of Calgary:

responsible winter practices around stormwater systems

Instead of skating on storm ponds, consider safer alternatives that also take stormwater management into account. Look for public skating rinks or other monitored bodies of water that have been tested for safety. These sites are specifically designed for recreational use and provide the appropriate infrastructure to ensure that the conditions are safe and that stormwater management doesn’t impact their stability.

Even when engaging in winter sports or enjoying outdoor activities near stormwater systems, always stay informed about the local conditions. Many municipalities provide winter advisories regarding the state of stormwater ponds and the surrounding areas. Be sure to check for these updates before heading out.

As winter progresses, it’s also important to consider how our actions impact stormwater management systems. Shoveling snow responsibly and preventing ice buildup on roads and walkways helps minimize excess runoff that can overwhelm these systems. In turn, this reduces the risk of flooding and environmental damage in the spring.
