Glen Flora Tributary Hydrology Study

In November 2010, the Lake County Stormwater Management Commission (SMC) was awarded a Great Lakes Restoration Initiative (GLRI) grant from the US Environmental Protection Agency (US EPA) to study the surface water hydrology of an area located in the vicinity of the downstream end of the Glen Flora Tributary, which is within the Dead River Subwatershed.  The project, which is currently nearing its conclusion, included desktop assessment, field reconnaissance, and flow monitoring work to identify surface water inputs and outputs from the study area, identify surface water flow paths within study area, and characterize the depth, velocity, and volume of surface water flow passing into, through, and out of the study area.


The project focused on a portion of the Waukegan Harbor Extended Area of Concern (EAOC) that is bound to the west by the toe of a 30 to 35 foot high bluff, to the north by Montesano Ave. and the southern boundary of the Illinois Beach State Park, to the east by the western boundary of the Johns Manville site, and to the south by Greenwood Ave.  One of the unique features of the study area is that it represents a dividing line between some of the best preserved lands along the Lake Michigan shoreline in the state of Illinois (i.e., Illinois Beach State Park) and some of the most degraded ones (i.e., Waukegan Harbor Area of Concern). 


Over the past 20 years, the Waukegan Harbor Citizen’s Advisory Group (CAG) has been an important part of the ongoing efforts to cleanup and transform the Waukegan Harbor EOAC and to protect and restore the valuable natural resources found there, including the wetlands and small ravine streams that are located within the study area. Upon completion, the results of the Glen Flora Tributary Hydrology Study will help support and inform those efforts, as well as future vegetation management, wetland and stream restoration, and redevelopment decisions made within Waukegan Harbor EAOC.
