and not less than two hundred fifty (250) feet in length shall be constructed, thence a channel constructed not less than thirty-six (36) feet wide on bottom and not less than sixty (60) feet wide at water surface, to a point in the Desplaines River at or near Brandon Road and thence in the Desplaines River to Dresden Heights where the channel shall not be less than eight (8) feet in depth and one hundred fifty (150) feet in width. At or near Dresden Heights a lock and dam shall be constructed of suitable size, that shall conform in dimensions with other locks as provided in the Illinois River as hereinafter mentioned and water power developed as the property of the State of Illinois.

No work shall be done toward reconstructing Illinois and Michigan Canal between a point at or about Brandon Road and Dresden Heights prior to April first (1st) nineteen hundred and sixteen (1916); unless, before that time, the alleged rights now claimed by the Economy Light & Power Company to a dam and water power in the Desplaines River near the junction with the Kankakee River shall be finally declared valid by the Supreme Court of the United States.

The commission is authorized to collect data-make surveys, maps, etc., for the purpose of estimating and reporting to the Governor and the next General Assembly the cost of developing that part of the Desplaines River between Joliet and Brandon Road, and also the cost of developing power at Brandon Road and probable income from such power developed, with a view at an early date of incorporating the channel of the Desplaines River between the Sanitary District power house at or near Lockport, Ill., and Brandon Road into the Illinois Waterway, and for the purpose of conserving, preserving and developing for the State the water power that can be developed at or near Brandon Road in the Desplaines River, which would accrue to and be the property of the State.

"K" From a point at or near Dresden Island, hereinbefore described, the waterway shall follow the channel of the Illinois River for a distance of about twenty-four (24) miles, to a point in the Illinois River at or about the west end of Ballards Island, thence on an angle to a point on south bank about one thousand (1,000) feet east of the south end of dam at Marseilles, Illinois. This channel shall be dredged where necessary so as to secure a minimum depth of eight (8) feet and a width of not less than one hundred fifty (150) feet.

"L" From this point in the south bank of the river there shall be constructed a channel for purposes of navigation only, which shall afford a waterway not less than 8 feet in depth and a width of substantially 100 feet, with practically vertical walls, the center line of said channel ex tending for a distance of about 600 feet in a southwesterly direction to a point not less than 500 feet south of the top of the south bank of said river, and thence in a westerly direction, substantially parallel to the Illinois River, to a point at the south bank of the Illinois River near or opposite Bell's Island, but the northerly boundary line of the right of way for said channel through section twenty-four (24), township thirtythree (33) north, range four (4) east of the third (3rd) principal meridian shall no where be farther north of the center line of said channel than 100 feet hor shall it anywhere approach the top of the south bank of the Illinois River nearer than four hundred and fifty feet. No

material excavated from said channel in the first or most easterly 2,000 feet thereof, or so much of same as is situated in said section twenty-four (24), shall be placed or deposited on the northerly side of said channel.

Except as is hereinabove otherwise provided, the center line of said channel shall be as nearly as practicable the center line of the proposed waterway, as recommended by the United States engineers in their report and survey of the Illinois River during the year 1902 and 1904, as appears from Sheet No. 52 of said report and survey of the Illinois River now on file in the War Department at the United States Government.

That portion of the channel above described as the first 600 feet thereof, or any other part thereof as may be necessary for the requirements of navigation, may in the discretion of the commission be widened to a width of approximately 150 feet. A suitable guard lock or other safety device shall be installed in said channel. At the westerly or lower end of said channel, at or near its place of junction with the Illinois River, a lock shall be constructed of not less than 55 feet in width and of not less than 300 feet in length, and of a sufficient depth to maintain not less than 8 feet of water for navigation purposes between upper and lower levels. Said lock to be known as Lock "E." But nothing in this Act contained, nor anything the said commission may do thereunder, shall ever have the effect of, or be construed as creating, recognizing, establishing or enlarging any right, title, interest or claim of any person or corporation whatsoever in and to the said Marseilles Dam or any interest therein, or the right to maintain the same, in or to any water power thereby developed; nor as waiving, restricting, or limiting any right or power of the State of Illinois with respect to said dam or water power, or at any time hereafter preventing or interfering with the State of Illinois in the exercise of any right, power or option it may lawfully have in respect to or concerning the said dam or water power.

"M" Thence the channel of said waterway shall continue in the Illinois River at a depth not less than eight (8) feet and a width of channel of not less than one hundred fifty (150) feet, for a distance of about sixteen (16) miles below Marseilles Dam to a point just above Starved Rock, where a dam and lock shall be constructed; said lock to be designated and known as Lock "F."

"N." At the aforesaid point (described in paragraph "M") above Starved Rock in the Illinois River, there shall be constructed a permanent and substantial dam of concrete of the most modern design and type, at least equal to or better than the design and type of the dam across the Mississippi River at or near the city of Keokuk, Iowa, sufficient to control the water in the pool created by said dam to an elevation of one and one-half (12) feet above previous maximum high water at the highway bridge across the Illinois River at Ottawa. The elevation of the crest of this dam shall not exceed minus one hundred and twenty-one (121) Chicago city datum, and the water in the pool above said dam at the highway bridge at Ottawa shall be so controlled during all except flood stages of water that the elevation of the water at said highway bridge shall not exceed an elevation of minus one hundred and twenty-one (121) Chicago city datum. Whenever the stage of water at the highway bridge in the city of Ottawa shall exceed minus one hundred twenty-one (121) Chicago city datum, the sluice gates shall be immediately opened

and the stage of water shall be maintained at minus one hundred twentyone (121) Chicago city datum, as nearly as possible, and the said gates shall remain open, if necessary, to their full capacity to maintain said water at said stage, and if the excess water, with the sluice gates all open, shall still raise the stage of water above minus one hundred twenty-one (121) Chicago city datum, said sluice gates shall be kept open until the stage of water at said highway bridge shall again reach minus one hundred twenty-one (121) Chicago city datum.

The sluice gates in said dam shall be of capacity at least 30 per cent larger than any flood water flow of record, and shall be so controlled, operated and manipulated that the stage of water at the highway bridge at Ottaawa shall at no time exceed one and one-half (12) feet above the high water heretofore existing at said highway bridge across the Illinois River at Ottawa, Illinois. A lock designated as Lock "F" shall be constructed in connection with this dam; said lock shall have a width of not less than fifty-five (55) feet and a length of not less than three hundred (300) feet. Provision shall also be made at this site for enlarging this lock to a width of not less than eighty (80) feet and a length of not less than six hundred (600) feet, or an additional lock may be constructed not less than eighty (80) feet wide, and not less than six hundred (600) feet in length.

"O." In the construction of said dam at Starved Rock provision shall be made for the development of water power which may be created at this site. This power, as well as other water power created by water passing through said waterway or canal shall be utilized by the State and may be leased and the income therefrom shall be applied to the payment of the interest and principal on bonds issued for the construction of the work named herein.

"P." The channel of the Illinois River below the aforesaid dam shall be improved so as to secure a depth of not less than eight (8) feet of water, and a width of not less than one hundred fifty (150) feet, to a point at or near Utica.

"Q." The said Illinois Waterway shall be constructed so as to afford for navigation a channel of a depth of approximately, but not less than eight (8) feet throughout its course at all times. Additional depth of the channel as commerce may require, may be hereafter provided for through appropriate legislation, by and with the co-operation of the State and the Federal Government, when a sufficient depth of channel in the lower Illinois River and the Mississippi River shall have been attained or provided for by the Federal Government to warrant the deepening of the channel of the aforesaid Illinois Waterway; it being deemed and hereby declared that the said Illinois Waterway is practical for a general plan and scheme of deep waterway along the route hereinbefore mentioned, and is deemed most advantageous for such plan of deep water

way.

§ 7. Wherever, in the construction, maintenance, use and operation of any dam, controlling works, embankment, wall, crib or other improvement or structure, any existing drainage or sewer system constructed and maintained by any city, village or incorporated town is destroyed or materially interfered with, then it shall be the duty of the Illinois Waterway Commission to alter, rebuild or reconstruct or otherwise provide for

so much and such parts of such drainage and sewer systems as to restore the same to as good efficiency as before the passage of this Act. In the altering, rebuilding and reconstructing of such drainage and sewer systems, streets, avenues, alleys and private property shall be replaced and restored to as good a condition as they were before said work was commenced. The work of altering, rebuilding and reconstructing or otherwise providing for such drainage and sewer systems shall be done. by the commission under the general supervision of the city council or board of trustees of the city, village or incorporated town affected, and to its reasonable satisfaction, the whole cost thereof to be paid by the Illinois Waterway Commission, and the work to be done and completed prior to the completion of any dam or other work or structure causing such drainage or sewer system to be changed or interfered with.

Modern bridges of adequate size and of suitable design, including all necessary piers, abutments, sub-structures, superstructures and approaches, shall be constructed across the full width of the channel to replace present structures owned by municipalities, townships and counties, wherever changes or rebuilding in said existing bridges shall, in the opinion of the said Illinois Waterway Commission, become necessary, the original cost of the same to be borne by the Illinois Waterway Commission. One-half (2) of the cost of maintaining these bridges shall be borne by the municipality, township or county, and one-half (2) of such cost shall be borne by the State.

The work of building, constructing and paving approaches, retaining walls, and sidewalks, and other work made necessary by the raising and lengthening of bridge spans as aforesaid, shall be done by the Illinois Waterway Commission, under the supervision of city councils of cities, boards of trustees of villages, or the highway commissioners or other authorities having supervision of roads and bridges in the municipalities affected, and shall be paid for by the Illinois Waterway Commision.

At the city of Ottawa dykes shall be built along the east side of the Fox River and along the north side of the Illinois River commencing at or near a point at the center line of Shabbona Street produced to the Fox River and extending along the banks of the Fox River and Illinois River to a point at or near the intersection of Chester and Canal Streets, and the lowlands back of said dykes shall be filled with sand, earth or other material to an elevation of not less than minus one hundred and seventeen (117) Chicago city datum, all at the cost and expense of the Illinois Waterway Commission. In filling that part of said lowlands lying back of said dykes and lying south of Main Street and west of Division Street, the Illinois Waterway Commission shall fill the same to a depth of 18 inches from the top surface of said fill with good soil suitable for the raising of a good grass sod thereon. It shall also be the duty of the Illinois Waterway Commission to dyke and fill with sand, earth or other material the ravine in said city of Ottawa commonly known as the "West Side Ravine," from its junction with the Illinois River to a point at or near Ottawa Avenue, the elevation at the top of said dyke and fill to be minus one hundred and ten (110) Chicago city datum, all at the expense of the Illinois Waterway Commission.

All that land lying north and west of Fox River in the city of Ottawa from a point about midway between Madison and Jefferson Streets to a point at or near the aqueduct of the Illinois and Michigan Canal, and all that land lying north of the Illinois River between the Chicago, Burlington and Quincy railroad bridge and Clay Street shall be filled with earth, sand or other suitable material, so that no part of the surface of said land shall have a lower elevation than minus one hundred nineteen (119) Chicago city datum. No filling shall be done north of River Street, west of Ontario Street.

It shall be the duty of the city council of the city of Ottawa to procure the consent of the property owners whose lands are to be filled, but in case consent cannot be obtained by said city council, the said lands may be taken or damaged as is in this Act provided.

It shall also be the duty of the Illinois Waterway Commission, at its cost and expense, to dyke and fill with sand, earth or other suitable material, to an elevation of minus one hundred and ten (110) Chicago city datum, the following described property now owned by the State of Illinois, to-wit:

All that land lying to the west of the Fox River north of the Illinois River, east of LaSalle Street and south of the lateral canal or side cut, situated in the city of Ottawa.

Said land above described, excepting that portion thereof which is north of the south lines of blocks twenty (20) and twenty-one (21) of State's addition to the city of Ottawa, shall, when dyked and filled to the elevation aforesaid, be and the same is hereby dedicated to the public as a public landing, subject to any existing rights of any lessee thereof until the expiration of any such lease.

If, when said Illinois Waterway Commission is ready to fill said. land last above described, there shall be any valid and binding lease of or right to use any part of said land for a tail race, then such tail race shall be enclosed and covered by a suitable structure.

The work of building said dykes and of making the fills hereinbefore mentioned in this section shall be begun by said Illinois Waterway Commission immediately after the water is turned in on said dam and shall be completed by said Illinois Waterway Commission within one year from the time said water is first turned in against the said dam.

It shall be the duty of the Illinois Waterway Commission to build, construct and maintain, wherever necessary, along the north and south. sides of the Illinois River, exclusive of islands, from the dam at or near Starved Rock eastwardly to the city limits of the city of Ottawa, good, substantial and permanent walls or dykes of such character and materials as will prevent seepage from the river to the lands adjoining, the said walls or dykes to have a core of concrete, extending from top of said wall or dyke down to bed rock or hard pan, said core to be in thickness not less than one foot. The center line of said dykes or walls, from a point not more than 1,000 feet east of said dam to be constructed at or near Starved Rock shall not exceed a greater distance than 150 feet back from water line at normal stage of water: Provided, this requirement of proximity of 150 feet to the water shall not have. any application to that part of the north bank shore or edge of said. river lying or situate between the proposed dam and the commencement
