Flooding

Real-time information is now available for the Des Plaines River to help you determine actions to take in the event of a flood.

The Village, in partnership with the Lake County Stormwater Management Commission, U.S. Geological Survey, United States Department of the Interior, and NOAA National Weather Service Chicago, has installed a river gauge to measure the height of the water along the Des Plaines River.

The National Weather Service provides predictions as to how high the water will go based upon ground conditions, forecasted precipitation, and river hydraulics and hydrology.

Information on this website is the same information the Village uses to assess its response to flooding along the Des Plaines River.

The real-time data may be found on the National Weather Service website.

How to read the graph:
The stage of the river is the height of the water surface above a known elevation. In Lincolnshire, the gage datum listed as 629.98 (NAVD 1988). Based upon previous floods and response times, the Village has identified what will likely be observed at various stages. Specific responses are triggered when the National Weather Service predicts a certain stage will be reached. Below is a summary of those responses specifically for Lincolnshire along the Des Plaines River. These readings do not have any meaning for the Chicago River, Indian Creek, Lincolnshire Creek, or other areas along the Des Plaines River outside of Lincolnshire.

10.5 feet - Observation Stage
The observation stage is when Village Staff begins monitoring weather forecasts and the river gauge on a daily basis. Staff will begin assessing equipment and inventory needs at this time.

11.5 feet - Action Stage
The Action Stage is a "heads-up" stage at which the National Weather Service begins to issue river flood advisories and river forecasts. Village will begin servicing pumps and generators. Staff will order skids and sandbags as needed. Staff will also check all intake and discharge hoses are functional and order additional hose as needed.

12.5 feet - Minor Flood Stage
Water begins to overflow onto Londonderry Lane. If the river is forecasted to increase above 13.0, the Village will monitor Londonderry Lane to determine if closure of the road is warranted. Village officials will decide whether or not to close Londonderry Lane. Village will order 2-3 semi-loads of sand to be deployed at Spring Lake Park. Public Works Staff will begin making sandbags and placing them onto skids to be placed in designated locations.

14.0 feet - Moderate Flood Stage
Water begins to pond on Lincolnshire Drive at Wiltshire Lane. Londonderry Lane is closed between Lincolnshire Drive and 45 Londonderry Lane. At this point, the Village may deploy pumps along Lincolnshire Drive to assist in the removal of water from the pavement. Village Officials will close Londonderry Lane and close the flood control valves along Lincolnshire Drive. Pumping will begin at Wiltshire Drive and Londonderry Lane. Village will need to begin gathering volunteer information. At this stage the EOC (Emergency Operations Center) is now activated and in full effect out of Village Hall.

15.5 feet - Major Flood Stage 
Water approaches the top of the river bank on the east side of the Des Plaines River. The Village may initiate sand bag operations to protect Village facilities. Public Works will need to make a decision on whether or not to sandbag. The decision to sand bag or not sand bag will be based upon many factors, including but not limited to: forecasted crest elevation, forecasted time to crest, available resources, weather conditions, and safety of workers and volunteers.

16.5 feet - Evacuation Stage
At this stage the Village would require a mandatory evacuation of the residents on Lincolnshire Drive from Oxford Drive to Londonderry Lane. All residents would be advised to shut off any power sources. 17.5 feet – 100 Year Flood Stage (647.48) Lincolnshire Drive is closed from Cambridge Lane to Oxford Drive; Wiltshire Drive closed from Lincolnshire Drive to Cumberland; Cumberland Drive impacted; Oxford Drive between Half Day Rd and Essex Lane impacted; Stonegate Circle impacted; Half Day Rd between Village Hall and Oxford Drive (including Route 22 bridge over Des Plaines River) potentially impacted.

17.5 feet - 100 Year Flood Stage
Lincolnshire Drive is closed from Cambridge Lane to Oxford Drive; Wiltshire Drive closed from Lincolnshire Drive to Cumberland; Cumberland Drive impacted; Oxford Drive between Half Day Rd and Essex Lane impacted; Stonegate Circle impacted; Half Day Rd between Village Hall and Oxford Drive (including Route 22 bridge over Des Plaines River) potentially impacted.
