CHICAGO WATERWAY SYSTEM

The Chicago Waterway System (CWS) consists

of 78 miles of canals, which serve the

Chicago area for two principal purposes, the drainage of urban storm water runoff and treated

municipal wastewater effluent and the support

of commercial navigation. Other purposes

include recreational boating, fishing, streamside recreation and, where possible, aquatic

habitat for wildlife. Approximately

75 percent of the length are man-made canals where no

waterway existed previously and the remainder are natural streams that have been deepened,

straightened and/or widened to such an extent that reversion to the natural state is not

possible. The flow

of water in the CWS is artificially controlled by hydraulic structures. See

Figure

1.0 System Description

The Lockport'Controlling Works is one

of two outlet control structures for the CWS. All

flow from the CWS

740

square mile watershed discharges from the Chicago Sanitary and

Ship Canal (CSSC) to the Des Plaines River north

of the City of Joliet. The confluence is 1.1

miles downstream of the Lockport Powerhouse and Lock (LP&L). This reach is the upper end

of the Brandon Road navigation pool. The LP&L is the single outlet control for the CWS. It

should be noted that on Figure

1, distances on the CWS are measured from the LP&L. The

CWS has two river systems, the Calumet River system and the Chicago River system.

The Calumet River system is 23.1 miles

length and includes the Calumet-Sag Channel

(CSC) and the Little Calumet River (LCR). The Chicago River system consists of 55.1 miles

of waterways and includes the Chicago River, CSSC, North Branch, North Branch Canal

(NBC), North Shore Channel (NSC), South Branch and South Fork. The South Fork is

commonly known as Bubbly Creek. Each river system will be described separately.

1.1 Chicago River System

The CSSC extends upstream from the confluence with the Des Plaines River for a distance

31.1 miles to South Damen Avenue in the City of Chicago (Chicago). The waterway then

becomes the South Branch, extending upstream for 4.5 miles to the junction

of the Chicago

River and the North Branch. The South Fork flows into the South Branch and extends

upstream for 1.3 miles, ending at 38

Street in Chicago. The Chicago River extends upstream

from the junction of the North and South Branches for 1.5 miles and ends at the Chicago

River Controlling Works (CRCW). The North Branch extends upstream from the junction of

the Chicago River and South Branch for 7.7 miles to the North Branch Dam, located south of

Foster Street in Chicago. The NBC is an alternate route around Goose Island between

Chicago and North Avenues and is 1.0 miles long. At the North Branch Dam, the waterway

becomes the NSC, extending upstream for

7,7

miles, ending at the Wilmette Pumping Station

(WPS).

1.2 Calumet River System

The CSC extends upstream from Sag Junction for 16.2 miles to the LCR. At this point, the

waterway becomes the LCR and extends upstream 6.9 miles, ending at the O'Brien Lock and

Dam (OL&D).

should be noted that the Calumet River extends upstream of the OL&D to

Lake Michigan. However, since the Calumet River is directly connected to Lake Michigan, it

is not considered part of the CWS. The water level and flow in the Calumet River cannot be

controlled the way that the CWS is controlled.

1.3 Tributaries to the CWS

There are several streams that contribute flow to the CWS. These include the Grand Calumet

River, LCR above its confluence with the CWS, the North Branch above the North Branch

Dam and

nUIIlerous small watersheds along the CSC and CSSC.

addition, there are

numerous small directly contributing areas along the CWS, including areas served by storm

sewers, parking lots, street ends, rooftop drains, etc.

2.0 Control and Management

of Flow

Flow in the CWS is managed by the Metropolitan Water Reclamation District of Greater

Chicago (MWRDGC), but is subject to regulation under U.S. Supreme Court Decree and 33

CFR Parts

2070420

and 207.425. The CFR provides for the maintenance of navigable depths

to support commercial navigation. The Chicago River at the CRCW and the LCR at the

OL&D must

be maintained between -0.5 feet Chicago City Datum (CCD) and -2.0 feet CCD

water levels per Code of Federal Regulations during normal conditions." This allows the

federal navigation project depths to be maintained throughout the CWS above the LP&L. .

The U.S. Supreme Court Decree governs the quantity

of water from Lake Michigan that is

diverted out of the Great Lakes Basin into the Mississippi River Basin by the State of Illinois

.(Illinois). Within Illinois, this quantity is subject to regulation by the Illinois Department of

Natural Resources, Division of Water Resources (DWR). The DWR issues allocation orders

for annual average quantities

of diversion. Most of the diversion is allocated to municipalities

for domestic consumption. The MWRDGC has an order that allows

to divert water for

improvement of water quality and this.is referred to as discretionary diversion. Currently and

through 2014, the MWRDGC allocation is for

an annual average of 270 cubic feet per second

(cfs).

2015, it is scheduled to be reduced to an annual average of 101 cfs.

additional annual average of 35 cfs is allocated to the MWRDGC for navigation makeup.

This is necessary to restore the CWS to the required water level for navigation following a

system draw down for wet-weather operations.

There are two other diversion categories which do not have a specific allocation, but for

which the DWR maintains a reserve quantity.

approximate annual average of 100 cfs is

the reserve needed for operation of the locks at CRCW and OL&D for passage of navigation

traffic. Another approximate annual average of 50 cfs is reserved for leakage through the

walls and structures separating the lake and river. The actual amount

of each of these reserves

varies with the level

of Lake Michigan.

Accounting

for the amount of water diverted from Lake Michigan is the responsibility of the

DWR and the U.S. Army Corps

of Engineers (USACE), Chicago District. The measurement

of quantities of diversion and the method of accounting are specified in the U.S. Supreme

Court Decree and in a

1996 Memo of Understanding between the U.S. Department of Justice

and the several states bordering the Great Lakes.

3.0 Inflow and Outflow

All outflow exits the CWS at the LP&L and Lockport Controlling Works (LCW). However,

there are several sources

of inflow to the CWS. These include WRP effluent, discretionary

diversion, navigation and leakage, tributaries, storm

runoff and combined sewer overflows.

3.1 Outflow

The average annual flow leaving the CWS in Water Year

(WY) 2001 was 2,710 cfs as

measured by

the U.S. Geological Survey (USGS) at Romeoville Road. Maximum and

minimum daily discharge during WY

2001 was 13,700 and 1,200 cfs, respectively. Since

1986, the maximum and minimum WY annual average discharges have been 4,110 and 2,560

cfs, respectively. The maximum instantaneous discharge was 19,500 cfs on February 21,

1997.

There are periods of zero and negative discharge due to operations at the LP&L and the

hydraulic peculiarities

ofthe CWS.

3.2 WRP Effluent

0yeEZ9percentoftb.e,l:U1llual flow in the system is from the discharge of treated municipal

.wastewater effluent from the Calumet, Lempnt,NorthSide and Stickney Water Reclamation

Plants (WRPs) owned and operated by the MWRDGC. The WRPs are also shown on Figure

1. These WRPs have the following flow characteristics in cfs:

3.3 Discretionary Diversion

Discretionary diversion is introduced into the system from Lake Michigan to maintain

adequate water quality. This occurs at three locations, WPS, CRCW and OL&D, shown on

Figure

1. Discretionary diversion is seasonal and is cheduled such that most flow is during

warm weather months of June through October. Some flow is scheduled throughout the year

for the NSC

due to more sensitive water quality conditions. Discretionary diversion flows in

cfs for calendar year 2001 were as follows:

3.4 Navigation and Leakage

1bis flow consists of discharge to support navigation in the operation of locks and leakage

through structures and walls separating the lake and river. There is no navigation traffic at the

WPS.

should be noted that navigation flows are seasonal. In addition, the quantity is

dependent on the lake level, since flow at CRCW and OL&D is by gravity only. Leakage,

fonnerly a significant quantity at CRCW, has been reduced through repair

of gates and

construction of new walls. The average annual, monthly maximum and monthly minimum

flows at each

of these facilities in cfs for calendar year 2001 were as follows:

The average annual discharge for WY 2001 measured by the USGS downstream from the

three intake facilities CRCW, OL&D and WPS is 312, 217 and

80 cfs, respectively.

3.5 Tributaries

The major watersheds tributary to the CWS are the LCR, over 210 square miles, and the

North Branch,

113 square miles. Other tributaries discharging into the CSC include Crooked

Creek, East Stony Creek, Illinois and Michigan Canal, Midlothian Creek, Mill Creek, Navajo

Creek, Saganashkee Slough, Tinley Creek and West Stony Creek. Tributaries discharging into

the CSSC include the Illinois and Michigan Canal diversion ditches and Summit-Lyons

Conduit. Please refer to the CWS Listing

of Facilities, Inflows and Monitoring Locations

(CWS List).

3.6

Storm. Rti.ribff

Numerous storm sewers discharge to the CWS from several municipalities and Illinois

Department

of Transportation drainage facilities. A complete inventory of these facilities

needs to be assembled.

3.7 Combined Sewer Overflow

Several hundred CSOs discharge to the CWS from several municipalities and the MWRDGC.

The MWRDGC

is currently preparing a comprehensive CSO outfall inventory.

4.0 Physical Description of Waterways

4.1 CSC

5.0 Use Classification

5.1 General Use Waters

.This use classification has been designated by the IPCB for the 1.6 mile length

of the Chicago

River and the 4.0 mile reach

of the North Shore Channel from the North Side WRP outfall to

the WPS. The General Use standards are found at 35 lAC Section 302.200 and are established

to protect aquatic life, wildlife, body-contact recreation (swimming), water supply and

Secondary Contact uses.

5.2 Secondary Contact Waters

All other portions

of the CWS have been designated by the IPCB for this use classification.

The Secondary Contact standards are found at 35 lAC Section 302.400 and are established to

protect indigenous species, non-contact recreation (boating) and commercial navigation.

6.0 Facility Descriptions

6.1 CRCW

The CRCW controls the flow of water between the lake and Chicago River. This facility was

built by the MWRDGC in 1938 and was maintained and operated by them until 1984.

this

year, the maintenance and operation responsibilities were transferred

to the USACE.

consists of walls separating the river and the lake, a navigation lock, two sets of sluice gates

and a pumping station. The lock is 80 feet wide by 600 feet long, with a normal lift of 2.0

feet. The two sets

of underwater sluice gates consist of four gates each, each gate being 10 by

10 foot in size. The pumping station has three pumps of 30 cfs each. The pumps can only

discharge from the river to the lake and were installed in 2000 for the purpose

of returning

excess leakage and lockage water to the lake. The pumps have yet to be used for this purpose.

6.2LCW

The LCW

is owned and operated by the MWRDGC. It is an auxiliary facility used during

storm operations to discharge flood waters

to the Des Plaines River.

is located two miles

upstream

of the LP&L and is used when discharge above the capacity of the LP&L is needed.

has 7 sluice gates, each being 30 feet wide and 20 feet high. The gate sill is at elevation -

15.0 feet, CCD.

6.3 LP&L

The Powerhouse is owned and operated by the MWRDGC.

was built in 1907 and is

currently licensed for two hydroelectric generating units with a total capacity

of 13,500

kilowatts, 9 submerged sluice gates for the discharge

of storm water and one surface sluice

gate for flushing debris. The lock

is owned and operated by the USACE and was built. in

1933.

is 110 feet wide and 600 feet long with a normal lift of 37 feet.

. Newly licensed generating units will have combined capacity of 5,000 cfs. Each submerged

sluice gate

is capable of a maximum discharge of 2,500 cfs. A fill or empty event for the lock

during normal water levels causes a discharge

of 2,000 cfs over a 20-minute period. During

storm operations, the upstream water level lowers and the discharge capacity through the

facility

is lessened. Also, because of structural concerns, all of the submerged sluice gates at

the Powerhouse are not used simultaneously.

6.4 OL&D

This facility was built in 1960 and is owned and operated by the USACE. The lock

is 110 feet

wide and 1,000 feet long with a normal lift 2.0 feet. Flow regulation is accomplished with 4

submerged sluice gates, each

10 by 10 feet in size. The gate opening for flow regulation is

under the direction

of the MWRDGC and the actual operation is performed by the USACE.

6.5 WPS

The WPS

is located beneath and is integral with the Sheridan Road Bridge and controls the

flow of water between Lake Michigan and the NSC. It was built in 1910 and is owned and

operated by the MWRDGC. Lake water is brought into the channel for augmenting low flows

for water quality maintenance. The station has four horizontal screw pumps rated at 250 cfs at

a lift

of 3.0 feet. The pump propellers are 9.0 feet in diameter and located in tunnels that run

under the floor

of the station from the Wilmette Harbor to the channeL Pumping is necessary

when lake levels are low.

Adjacent to the south side

of the pumping station is a concrete channel and sluice gate to

allow for the passage of water by gravity when pumping is not necessary. The channel is 30

feet wide and

11 feet deep. During storm operations, when the channel surcharges and the

water level nears 5.0 feet, CCD, the sluice gate

can be opened to relieve the channel to the

lake.

Five temporary pumps with an aggregate capacity

of 50 cfs, were installed in 2000 due to

non-operation

of the large original pumps.

2002, one of the original pumps is being

rehabilitated for use since the five temporary have insufficient capacity for water quality

maintenance.

7.0 Operation Plan

7.1 Dry Weather Conditions

Normal dry weather discharge is released from the CWS through hydroelectric generating

units and the navigation lock at the LP&L.

The water level in the Chicago River at the CRCW

and in the LCR at the OL&D is maintained at -2.0 feet, CCD. Discretionary diversion is

brought into the CWS at the CRCW, OL&D

and WPS per the planned schedule.

7.2 Wet-Weather Conditions

When weather forecasts indicate that rainfall is likely to occur, the CWS is readied for wet-

. weather operations. Discretionary diversion, if in progress, is curtailed and discharge at the

LP&L is increased. This lowers the water level

in the lower reaches of the CWS to provide

storage for incoming storm flow and increases the hydraulic gradient to move more water

through and out

of the CWS. If no or very light rainfall occurs, the operations are returned to

the dry weather mode. Light rainfall, less than 0.33 inches, normally causes little disruption in

operations.

If rainfall is moderate, 0.33 to 0.67 inches, most CSO is initially contained in TARP and only

reaches the CWS through increased discharge from the WRPs. Direct inflow

of other storm

runoff is generally not significant

or problematic. Additional discharge at the LP&L is

achieved by increasing the discharge through the LP&L generating units to their maximum

capacity. Discharge needed beyond the

maximum discharge of the generating units is put

through sluice gates at the

LP&L and, if necessary, the LCW. Water levels in the upper part

of the CWS will rise due to storm inflow and increased WRP discharge. After the peak water

level is reached, the water levels begin to subside. Discharge at the LP&L is gradually

reduced as the CWS returns to dry weather conditions. When -2.0 feet, CCD, is reached

at the

CRCW and/or OL&D, discretionary diversion is resumed,

if appropriate.

If rainfall is heavy, 0.67 to 1.5 inches, TARP will fill and excess CSO will be discharged to

the CWS from pumping stations and combined sewer outfalls. Other storm runoff from

tributary watersheds and storm sewers is significant and imposes an additional hydraulic load

on the CWS. The operation

of the CWS will be similar to the above description, with the

exception that increased discharges at the LP&L are initiated more rapidly.

Excessive rainfall,

1.5 inches or greater, especially if preceded by antecedent rainfall, will

most likely cause extreme water levels in the upper part of the CWS. If water levels reach 3.5

feet, CCD, and are rising, it will be necessary to relieve the

ews by discharging excess flood

water to Lake Michigan at the CRCW, OL&D and/or WPS.

The decision to provide for such

relief at each facility

is made based on the potential for continued area rainfall and on the

water level conditions

at each facility.

with over 200 monitoring locations. Two

of these are located on the CWS, on the CSC at

Route

83 and on the csse at Lockport.

9.2MWRDGC

MWRDGC also operates an AWQM program and has 20 locations on the CWS. In addition,

MWRDGC performs monitoring for biological conditions, physical habitat and sediment

quality at all these locations. At some locations, the monitoring is performed annually and at

others, once in four years. In addition, there are 30 locations

in the CWS where dissolved

oxygen and temperature are measured hourly

with

continuous in-situ monitors. See the CWS

List.
