How Many Inches of Rain Does It Take to Fill Lake Michigan?

This morning landscape architect Deidre Toner kindly forwarded information from The Morton Arboretum which said that 17.81″ of rain have fallen there in 2013. In April, the official count was 9.78″ of rain! I got pretty pumped thinking that must mean that Lake Michigan has completely recovered from being two feet below “normal”. But (duh), Queen Bee, think again and maybe have another cuppa coffee this morning. Seventeen inches translates to only two inches spread across Lake Michigan, according to the US Army Corps of Engineers. If you are a weather freak, here’s the link to the Corps’ charts on Lake Michigan water levels: http://www.lre.usace.army.mil/Missions/GreatLakesInformation/GreatLakesWaterLevels/WaterLevelForecast/WeeklyGreatLakesWaterLevels.aspx

Erosion on beach at Lake Road 4-19-2013 3-34-56 PM 4320x3240By the way, I’m posting this nasty photograph which shows how a significant slice of beach eroded in Lake Forest after the deluge of April 18, 2013. Water from municipal and private stormwater pipes ran so fast and furious down the narrow ravine leading to this section of beach that it cut this sharp gouge in the sand. There’s much to be done to solve these (highly solveable) erosion problems, but there is a dedicated team of people working on regional solutions. The Alliance for Lake Michigan has produced an excellent ravine webinar. You will not regret spending an hour listening–and if you are a ravine or bluff owner or if you are in the landscape contract and design trade, please sign up for their emails because the Alliance, together with Openlands and “Plants of Concern”, is working on creating brochures of plants appropriate for various ravine conditions, a “rapid response assessment program” for training gardeners in assessing ravine health, and educational ravine seminars at the Chicago Botanic Garden. Thank you, Alliance!##
