7/13/17 2:00 p.m. Emergency Management Partners Update

Lake County Board Chairman Aaron Lawlor signed a proclamation declaring that severe flooding has created a disaster in Lake County, Illinois. The proclamation was signed late Wednesday night and sent to Governor Rauner and the Illinois Emergency Management Agency.


Heavy rain caused localized flash flooding of streets, yards, homes and businesses, and we are currently monitoring flooding of several rivers, streams and lakes in Lake County that is taking place over the next couple of days. 

Fox River/Chain O'Lakes
Those who live along or near the Fox River and Chain O'Lakes should prepare for high water over the next several days and pay attention to future forecasts. According to the IDNR, the Fox River in New Munster, WI is cresting today at 17.4 feet and is currently moving 9700 cubic feet per second (cfs.) toward the Chain O'Lakes, which is anticipated to arrive in the Chain tomorrow. The current forecast is for 13,400 cfs. inflow into the system on Friday. This flow is higher than we have seen on the Chain, so our lake and river stage estimates are included from our known information, but there is some uncertainty because we have nothing to compare them with. 

The gates at Stratton and Algonquin are open to their maximum to draw down the water before the peak gets here tomorrow.

The current estimate forecast shows the following peak river/lake stages between July 16-17. Flooding of this magnitude has not been seen before.

  • Fox Lake gage may crest over 8.2 feet. The current stage is 6.01 feet.
  • Stratton HW gage will crest over 6 feet. The current stage is 4.21 feet.
  • Stratton TW gage may crest over 8.5 feet. The current stage is 5.15 feet.

Des Plaines River
The Des Plaines River at Russell is currently at 11 feet, which is approaching record flood stage of 11.1 feet. A crest of 11.4 feet is forecast to occur this evening. 

At Gurnee, the current stage is 10.98 feet, and is approaching major flood stage of 11 feet. A crest of 12 feet is forecast to occur tomorrow night. 

At Lincolnshire, the current stage is 16.48 feet, and is SLOWLY DROPPING. A crest of 17.3 feet is forecast to occur around mid-day on Saturday. However, based on a correlation with the 2013 flood event, the Des Plaines River around Lincolnshire MAY have crested. Levels in Libertyville and Lincolnshire were reported to be holding or decreasing. The discrepancy between the forecast, observations, and historic data are being discussed with the National Weather Service. 

*We are currently working on Des Plaines River Inundation Maps, and will make them available as soon as possible.

The levee is stable and at this time evacuation is not anticipated.

Emergency Management

EOC Management Coordination Teams have been formed to reach out to all communities to specifically obtain status updates and coordinate with local Emergency Management Partners. It is imperative that local communities provide contact information for a representative that can report on the current level of damage to structures, critical infrastructure and roadways; and any closures of schools or businesses.

In turn, Lake County can obtain information from communities regarding the need for supplies and equipment that the County can provide.  This includes:
