DECREE
This Court having reopened Original cases Nos. 1, 2, and 3, and
having granted leave to file Original case No. 11, and having
referred all such cases to a Special Master who has filed his
Report, and the parties having agreed to the form of the decree,
the Findings of Fact in the Report are hereby adopted, and it being
unnecessary at this time to consider the Special Master's legal
conclusions,
IT IS ORDERED, ADJUDGED, AND DECREED that:
1. The State of Illinois and its municipalities, political
subdivisions, agencies, and instrumentalities, including, among
others, the cities of Chicago, Evanston, Highland Park, Highwood
and Lake Forest, the villages of Wilmette, Kenilworth, Winnetka,
and Glencoe, the Elmhurst-Villa Park-Lombard Water Commission, the
Chicago Park District and the Metropolitan Sanitary District of
Greater Chicago, their employees and agents and all persons
assuming to act under their authority, are hereby enjoined from
diverting any of the waters of Lake Michigan or its watershed into
the Illinois waterway, whether by way of domestic pumpage from the
lake the sewage effluent derived from which reaches the Illinois
waterway, or by way of storm runoff from the Lake Michigan
watershed which is diverted into the Sanitary and Ship Canal, or by
way of direct diversion from the lake into the canal, in excess of
an average for all of them combined of 3,200 cubic feet per second.
"Domestic pumpage," as used in this decree, includes water supplied
to commercial and industrial establishments, and "domestic use"
includes use by such establishments. The water permitted by this
decree to be diverted from Lake Michigan and its watershed may be
apportioned by the State of Illinois among its municipalities,
political subdivisions, agencies, and instrumentalities
Page 388 U. S. 428
for domestic use or for direct diversion into the Sanitary and
Ship Canal to maintain it in a reasonably satisfactory sanitary
condition, in such manner and amounts and by and through such
instrumentalities as the State may deem proper, subject to any
regulations imposed by Congress in the interests of navigation or
pollution control.
2. The amount of water diverted into the Sanitary and Ship Canal
directly from Lake Michigan and as storm runoff from the Lake
Michigan watershed shall be determined by deducting from the total
flow in the canal at Lockport (a) the total amount of domestic
pumpage from Lake Michigan and from ground sources in the Lake
Michigan watershed, except to the extent that any such ground
sources are supplied by infiltration from Lake Michigan, by the
State of Illinois and its municipalities, political subdivisions,
agencies, and instrumentalities the sewage effluent derived from
which reaches the canal, (b) the total amount of domestic pumpage
from ground and surface sources outside the Lake Michigan watershed
the sewage effluent derived from which reaches the canal, (c) the
total estimated storm runoff from the upper Illinois River
watershed reaching the canal, (d) the total amount of domestic
pumpage from all sources by municipalities and political
subdivisions of the States of Indiana and Wisconsin the sewage
effluent derived from which reaches the canal, and (e) any water
diverted by Illinois, with the consent of the United States, into
Lake Michigan from any source outside the Lake Michigan
watershed.
3. For the purpose of determining whether the total amount of
water diverted from Lake Michigan by the State of Illinois and its
municipalities, political subdivisions, agencies, and
instrumentalities is not in excess of the maximum amount permitted
by this decree, the amounts of domestic pumpage from the lake by
the
Page 388 U. S. 429
State and its municipalities, political subdivisions, agencies,
and instrumentalities the sewage and sewage effluent derived from
which reaches the Illinois waterway, either above or below
Lockport, shall be added to the amount of direct diversion into the
canal from the lake and storm runoff reaching the canal from the
Lake Michigan watershed computed as provided in paragraph 2 of this
decree. The accounting period shall consist of the period of 12
months terminating on the last day of February. A period of five
years, consisting of the current annual accounting period and the
previous four such periods (all after the effective date of this
decree), shall be permitted, when necessary, for achieving an
average diversion which is not in excess of the maximum permitted
amount; provided, however, that the average diversion in any annual
accounting period shall not exceed one hundred ten (110) percent of
the maximum amount permitted by this decree. The measurements and
computations required by this decree shall be made by the
appropriate officers, agencies, or instrumentalities of the State
of Illinois under the general supervision and direction of the
Corps of Engineers of the United States Army.
4. The State of Illinois may make application for a modification
of this decree so as to permit the diversion of additional water
from Lake Michigan for domestic use when and if it appears that the
reasonable needs of the Northeastern Illinois Metropolitan Region
(comprising Cook, Du Page, Kane, Lake, McHenry, and Will Counties)
for water for such use cannot be met from the water resources
available to the region, including both ground and surface water
and the water permitted by this decree to be diverted from Lake
Michigan, and if it further appears that all feasible means
reasonably available to the State of Illinois and its
municipalities, political subdivisions, agencies, and
instrumentalities
Page 388 U. S. 430
have been employed to improve the water quality of the Sanitary
and Ship Canal and to conserve and manage the water resources of
the region and the use of water therein in accordance with the best
modern scientific knowledge and engineering practice.
5. This decree shall become effective on March 1, 1970, and
shall thereupon supersede the decree entered by this Court in Nos.
1, 2, and 3, Original Docket, on April 21, 1930, as enlarged May
22, 1933, provided that, for the period between January 1, 1970,
and March 1, 1970, the amount of water diverted by Illinois into
the Sanitary and Ship Canal (determined in accordance with
paragraph 2 of this decree) shall not exceed an average of 1,500
cubic feet per second.
6. The complaint of the State of Illinois in No. 11, Original
Docket, on behalf of its instrumentality, the Elmhurst-Villa
Park-Lombard Water Commission, is hereby dismissed, without
prejudice to that Commission sharing in the water permitted by this
decree to be diverted from Lake Michigan.
7. Any of the parties hereto may apply at the foot of this
decree for any other or further action or relief, and this Court
retains jurisdiction of the suits in Nos. 1, 2, and 3, Original
Docket, for the purpose of making any order or direction, or
modification of this decree, or any supplemental decree, which it
may deem at any time to be proper in relation to the subject matter
in controversy.
8. All the parties to these proceedings shall bear their own
costs. The costs and expenses of the Special Master shall be
equally divided between the plaintiffs as a group and the
defendants as a group in Nos. 1, 2, and 3, Original Docket. The
costs and expenses thus imposed upon the plaintiffs and defendants
shall be borne by the individual plaintiffs and defendants,
respectively, in equal shares.
