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.
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
in
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
of
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
th
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
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).
It
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.
In
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
it
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).
In
2015, it is scheduled to be reduced to an annual average of 101 cfs.
An
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.
An
approximate annual average of 100 cfs is
the reserve needed for operation of the locks at CRCW and OL&D for passage of navigation
2
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
3
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.
It
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
A man-made channel, the CSC is 16.2 miles long with a generally trapezoidal shape, 225 feet
wide and approximately
10 feet deep. In some sections, the north bank is a vertical walL The
alignment
is generally straight with three bends near Crawford, Ridgeland and Western
Avenues.
4.2 Chicago River
The Chicago River,
1.5 miles in length, is 200 feet wide west of Michigan Avenue and wider,
up
to 250 feet, east thereof.
It
has vertical side walls throughout its length.
It
is 20 feet deep at
the west end and 26 feet deep at the east end. The river alignment is generally straight with
three bends.near Michigan Avenue and Orleans
and State Streets.
4.3 CSSC
This 31.1 mile long man-made channel has many different shapes and sizes. Its alignment is
straight throughout its length, except for four bends, near Harlem Avenue, LaGrange and
Romeoville Roads and in Lockport. Downstream
of the LP&L, a reach of 1.1 miles, the depth
is
10 feet and the width is 200 feet. Upstream of the LP&L, the depth varies from 20 to 27
feet. The reach immediately upstream
of the LP&L, 2.4 miles in length; varies in width from
160 to 300 feet. The east bank of this reach is a vertical concrete wall. The. west back varies
from vertical dock wall
to a steep rockfill embankment. The next 14.6 miles of the CSSC
have vertical concrete or rock walls 160 feet apart. The last
13.0 miles have a trapezoidal
shape, 220 feet wide, with steep earth or rock side slopes. There are several areas with vertical
dock walls in this last reach.
4.4 LCR
The LCR,
6.9 miles in length, has been deepened and widened from its original natural
condition. There are several changes
in
alignment, with one full 180-degree bend west of
Indiana Avenue. Its width varies from 250 to 350 feet and its depth is generally 12 feet in the
center part
of the channel.
It
has few vertical dock walls and most of the banks are earthen
side slopes.
4.5 North Branch
From the junction
of the Chicago River and South Branch to Belmont Avenue,
a
distance of
5.1 miles, the river follows its original course, has several bends and has been deepened and
widened. The width varies from 150 to 300 feet and the depth varies from
10 to 15 feet.
In
several reaches, vertical dock walls have been constructed and are in varies states of disrepair.
From Belmont Avenue
to the North Branch Dam, 2.6 miles, the channel has been either
straightened or relocated into fairly straight segments with steep earthen side slopes. The
width is generally 90 feet and the depth is approximately
10 feet in the center part of the
channeL
5
4.6 North Branch Canal
This canal was man-made in the 1870s.
It
forms the east side of Goose Island, has a straight
alignment and is one mile in length. The width varies from 80 to 120 feet and the depth from
4 to 8 feet.
4.7NSC
This man-made channel is 7.7 miles in length and is straight throughout except for four bends
in alignment near Devon and Central Avenues and Emerson and Linden Streets.
It
has steep
earthen side slopes and a width
of 90 feet. The depth varies from 5 to 10 feet.
4.8 South Branch
This 4.5 mile long segment generally follows its original course and has several bends. A
short relocated reach between Roosevelt Road and
18
th
Street was relocated in 1928 to
eliminate a major bend.
It
has vertical dock walls throughout most of its length. The width
varies from 200 to 250 feet and the depth from
15 to 20 feet.
4.9 South Fork
This segment is
1.3 miles in length, varies from 100 to 200 feet
in
width and from 3 to 13 feet
in depth. There are several sections with vertical dock wall, but most
of the banks are steeply
sloped earth or
rock materials.
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.
In
this
year, the maintenance and operation responsibilities were transferred
to the USACE.
It
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.
It
is located two miles
upstream
of the LP&L and is used when discharge above the capacity of the LP&L is needed.
It
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.
It
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.
It
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
7
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.
In
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.
8
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.
8.0 Measurement

9.0 Monitoring
of Water Quality
9.1 IEPA
IEPA operates an Ambient Water Quality Monitoring (A
WQM) program throughout Illinois
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
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.
9.3
USEPA
USEPA performs no regular monitoring, but has conducted surveys of sediment quality for
some reaches
of the CWS.
