Lead levels spike in Lake Cda

This home is one of many that got caught in the flooding in Cataldo, Idaho, on Jan. 18. At peak flow on that day, water samples taken at Harrison had the highest lead reading since February 1996.

An estimated 352,000 pounds of lead washed into Lake Coeur d’Alene on Jan. 18 after flooding related to a rain-on-snow event.

That’s the weight equivalent of 70 Dodge Ram 1500 pickups – and the highest volume of lead recorded in a 24-hour period since major flooding in February 1996.

Greg Clark, a U.S. Geological Survey hydrologist, attributed high lead concentrations to a rapid rise in the Coeur d’Alene River caused by pounding rains and melting snow. At Harrison, where the river empties into Lake Coeur d’Alene, the Jan. 18 flows averaged 19,000 cubic feet per second. Becky Kramer, SR

How worried are you about high lead concentration in Lke Coeur d' Alene?
