The Nickell Lake ice and snow cover has fallen below the required 4-inch minimum. The City of Columbia's Stephens Lake Property will remain open for skating. The lake was inspected on January 5 and the ice was tested at just over 10-inches thick. Stephens remains open for sledding and cross-country skiing. Users must be cautious as the ice is not checked on the weekends, holidays or evenings, so skaters should be aware that ice that was determined safe one day, may not be safe the next.
Many factors affect ice quality.
Ice is subject to variable freezing temperatures from above, and yet constantly thawing temperatures below due to water temperatures in the 40-degree fahrenheit range. Wind whipped water, areas where there is any water movement due to either overland runoff or underground springs, and shaded or sunny areas, all lead to freezing and thawing conditions. Snow is another problem as snow cover acts as an insulator and ice may actually begin to melt despite freezing temperatures. Remember that even when the lakes are determined safe for skating, never skate alone and do not gather in large groups on one spot. Do not skate after dark and please warn other skaters of dangerous conditions.
