Safety First When Venturing Onto The Ice

Montana’s mild winter has made judging ice conditions on many low valley lakes and reservoirs a tricky call for even the most experienced outdoor recreationist. "Anglers, snowmobilers, ice skaters and others should use extreme caution whenever venturing onto the ice," said Liz Lodman, coordinator of Montana Fish, Wildlife & Parks’ vehicle safety program. Sunny days and warm winds are not the only conditions affecting ice thickness and strength, Lodman said. Springs and rising or moving water erode ice on its underside. This erosion often isn’t visible and is usually uneven -- some areas are weakened, while others are not. Ice covered by a layer of slush or water, and ice with dark-colored spots, indicates thin ice that should be avoided. "Never assume ice is safe by just looking at it," warned Lodman. "Use an auger or spud bar to test the thickness and condition of ice. Since ice usually melts faster along shorelines, anglers should leave their vehicles on the shore." Also, ice that appears safe in the morning can quickly melt by afternoon, leaving a recreationist stranded, Lodman said.
