Lake Levels UpdateJune 20th, 2013 at 5:52 pm by Bill Steffen under Bill's Blog, Weather
This is the Ludington North Pier Lighthouse – picture from Jack Martin. The Great Lakes continue to gain water. This is one of the biggest spring increases in the volume of water in the Great Lakes since records began over 100 years ago. Lake Michigan/Huron (at the same water level – connected at the Strait of Mackinac) rose another 2″ in the last two weeks. The level is up 5″ in the last month and is now only one inch below the level of one year ago (we’ll bounce into the plus column here soon). The level is now 12″ above the lowest June level of 1964, but still 19″ below the long-term average. Lake Superior added one inch in the last two weeks. Superior has gained 4″ in the last month and is at the same level as one year ago. It’s 7″ below the century average. Lake Erie is up 3″ in just the last 2 weeks, and 7″ in the last month. Erie is now 2″ above the level of one year ago and only 3″ below the long-term average. Lake Ontario did even better, up 6″ in just the last 2 weeks and 11″ in the last month. Lake Ontario is now 10″ above the level of one year ago and 4″ ABOVE the long-term average. South Lake Michigan (south of Manistee) water temperatures are between 55 and 60.
Saturday is Beach Survival Challenge at Grand Haven State Park. Here’s the Beach Survival facebook page. I’ll be there by 10 AM and I’ll stay thru the Noon Hour. Even if you’re not signed up for the event, stop on by to see the the competition and say “hi”. Here’s some water safety rules.
