How Ice Forms in Lakes and Ponds

Lakes and ponds cool down in the early fall. At first, warmer water from below is brought to the surface by convection currents. When the temperature drops to around 3-4 degrees C, the surface water becomes less dense and stays on top, in a stationary layer. This layer just needs a nudge of a few degrees to reach the freezing point and ice begins to form on top of the lake or pond. Using a fresh-water lake in Central Canada as an example, the temperature directly under the ice will be around zero and will get warmer as you move towards the bottom, to 3-4 degrees C maximum. The change in water temperature with depth will depend on several factors; lake depth, lake currents, type of lake bed (silt, sand, stone). In any given year, the lake water temperature can be affected by weather conditions such as precipitation and wind. The important fact is that a temperature gradient exists in most lakes and ponds, and this stored heat in the lower layers not only keeps aquatic creatures alive, but can be used for ice prevention and deicing. How fast does ice form? This depends on the size of the lake, the ambient temperatures, the lake depth and conditions. It’s important to note that a man-made pond or shallow water body may freeze over quite quickly whereas a lake may take several months.

Why Ice is a Problem

One of the unique properties of water is that when it freezes and changes to ice it expands approximately 9%. If ice forms between two fixed surfaces, like your dock or boat crib, and a shoreline for example, the expansion causes pressure between the two surfaces. Surface ice will go through frequent cycles of freeze thaw, and damage is caused by repeated cycles of release and expansion pressure. Ice sheet expansion can splinter, crack and even break up docks and marine structures. Ice expansion against a boat or yacht can cause thousands of dollars of damage. Ice jacking or ice heaving is a caused by changes in water level or by a lifting action. Again the powerful action of ice from a large sheet of lake ice can lift lake bed pillings out of their footings and lift a dock right out of the water. Ice flow damage is unpredictable and sometimes difficult to prevent. In the spring or late winter, ice around the shoreline begins to melt and sheets of ice can break-up and be moved by currents and wind. Ice can also be a problem for industries trying to protect water in-take screens, pumping stations, submersed structures and equipment. Open water can ensure continued plant operation and protect valuable company assets.

How a Deicer Works - Heat & Motion

There are 2 mechanisms that will melt ice or prevent it from forming on the surface of a lake or pond, heat and motion. Warmer water below the surface and reaching down to the lake bottom, is only slightly more dense than the colder surface layer, and therefore, very little work is needed to raise it to the surface. That’s good news! It means even a propeller deicer with a low HP motor can be very effective at moving warm water to the surface where it’s heat can be used to melt ice. The agitation of the water as it is pushed up and through the propeller, causes thermal mixing, so the surface water temperature increases above freezing as the warmer water is brought to the surface. The propeller also creates a circulating motion or current around the deicer pushing ice away at the surface and drawing in warmer water from the surrounding lake bottom. When ice starts to form the ice particles flocculate and grow into crystals. The motion created by a deicer break up the crystals before they become large and this prevents the growth of ice. The ice particles are rapidly swept away from the deicer until they gradually slow and descend with currents where they disperse and melt in warmer water. Even is the heat in the subsurface water becomes depleted and little temperature gradient exists, the motion caused by a deicer is often sufficient to remove ice and maintain open water in the area.

The Difference Between 2 Deicing Technologies - Propeller Deicer and an Air Bubbler

Arbrux propeller type deicers are the most effective method of ice prevention. A bubbler using compressed air moves smaller volumes of water to the surface and is not nearly as effective at thermal mixing and water circulation as a propeller type deicer. An air bubbler will produce a vertical column of rising water where as a propeller de-icer creates a larger area of water circulation. The rate at which a propeller deicer can melt surface water and create open water is much faster than most air bubbler systems because of the improved thermal exchange and greater induced currents. Some people called propeller deicers, ice-eaters! A propeller deicer uses a submersed motor driving a propeller. They can be suspended at variable depths, but should be at least 3 feet from the lake bottom Our 1/2 HP deicers are perfect for protecting cottage docks or small boats. They circulate up to 500 GPM! You can run a deicer for set times during the day or have it operate automatically based on a temperature reading. The 1/2 HP Arbrux deicer is the same high performance quality as our industrial product line, so it’s built to last with zero maintenance. For commercial docks, marinas, barges, and industrial applications such as protecting water in-takes screens at manufacturing, power dams, and power plants - we have a full range of heavy duty deicers ready for the toughest conditions. Our 3 HP industrial deicer circulates a staggering 2,700 gallons per minute!
