Great Lakes Water LevelsMay 3rd, 2013 at 1:37 am by Bill Steffen under Bill's Blog, News, Weather
Picture taken May 2 of the flooding Ontonagon River in the U.P., courtesy MQT NWS. They say the flow on the river was up to 15,000 cfs or 20% of the flow over Niagara Falls! This is due to the rapid snowmelt. Snow cover on Thu. May 2: 15″ Hoist Basin, 10″ Atlantic Mine and 10 miles south of Grand Marais, 4″ at Ironwood (all new snow in the last 24 hours) and 1″ left at the Marquette Airport and at Mohawk. Lake Michigan/Huron is up one inch in the past week and up 9″ in the last month. The lake is down 6″ year-to-year and is still down 24″ from average, but it’s up 6″ above the low level of May 1964. Despite a dry weather pattern over the weekend into next week, the lake is still expected to add another inch due to above average river flows. Lake Superior is up 1″ in the past week and 4″ in the past month. The lake is down 1″ from May 2012 and is still 14″ below the century average. Lake Superior should also add an inch in the next week. Lake Erie is up 7″ in the last month and is now 7″ below average level. Lake Ontario is up 10″ in the last month and is 6″ below average level. If you add up all the water added to the Great Lakes in the last month, it comes to a staggering 11.8 TRILLION gallons of water added to the Great Lakes. Wow!
The South Lake Michigan buoy is back in the water, 40 miles west of Holland. At Midnight, it was showing an air temperature of 39.0, a water temperature of 39.9 and a north wind at 27 mph gusting to 33 mph. The North Lake Michigan buoy is also back in service and shows a water temperature of 36.9. Finally, they’re spending 198 million dollars to build a tunnel 200 feet under Lake Erie.
