Few Showers, But Dry Pattern Continues

Bill's Blog

While there may be a passing shower this Wednesday, the overall dry pattern will continue the rest of the week. The below average precipitation has brought down the water level of Lake Michigan by 15″ in the last year. The dry pattern has really brought down the flow on area rivers. The Grand River in Grand Rapids has a flow of just 48% of average for May 18 and the Muskegon River at Croton has a flow of just 34% of average for this time of year.

With above average flow out of the Great Lakes and below average flow into the Great Lakes, the water level of Lake Michigan will continue to fall slowly.
