Concrete Repair Assessment Lower Power Dam

SEH No. HUDSO 147444 14.00

Utility Director
City of Hudson
505 Third Street
Hudson WI 54016
Dear Mr. Peters:
An inspection was made on August 21, 2018 of the Lower Power Dam on the Willow River at Lake Mallalieu
(DNR Field File#55.04). The primary purpose of the inspection is to identify and qualify the concrete repair
needed at the dam and develop a construction cost estimate for budgeting. The need for the repair was
identified in the January 19, 2012 inspection report by Stantec and in the January 6, 2016 directive from the
Department of Natural Resources.
The Lower Power Dam is comprised of two separate dams, the primary structure has three tainter gates and an
abandon powerhouse that discharge directly on the shore of the St. Croix River. The second is a smaller single
sluice gate structure at Bridge Street that passes a small flow out through the channel beneath the Union
Pacific Railroad bridge. The concrete repair need was identified on the primary dam at the downstream end of
the pier between gates#2 and #3 (numbered from north to south) near the waterline and the operating floor of
the abandoned powerhouse directly to the south of the gates. There are other areas of concrete spalling and
joint deterioration, none of which are critical to the integrity of the dam and are not in need of repair at this time.
The secondary dam was in good condition with no repairs needed based on this observation or that of the
earlier inspection. Attached are photos of the overall primary and secondary dam and the areas requiring repair.
The downstream pier end concrete deterioration is approximately 6 inches deep by 5 feet high and has exposed
the reinforcement bars. The pier is 2'-3"wide and the damage extends across the end and approximately a two
feet onto each side of the pier. The deterioration is at the elevation of the normal or pool elevation of the St
Croix River and therefore will require a cofferdam to perform the work in the dry to obtain the best quality repair.
The cofferdam for this type of work is typically a fabricated box that is attached to the pier partially below the
waterline, sealed to the pier and pumped out to create a dry space to remove and place concrete to the original
like-kind dimensions. This type of cofferdam is less intrusive and less expensive than an earth or sheet pile
cofferdam. The estimated surface area of this repair is 36 square feet.
The powerhouse floor has a 28' x 24' x 1'4"thick lower level on which the generators had been and a 28' x 10'
x 1'-0"thick upper level, two feet higher. A 1'-3"thick concrete wall and stairs separate the levels. The wall
projects from the chambers below to the height of the upper floor level. These structural slabs span over the
turbine pit and gate areas. The slabs have deteriorated due to freeze-thaw cycles exasperated by water
standing on the surface. There are many previous patches and joints. It was recommend in the past inspection

to remove deteriorated concrete and place a concrete overlay with positive drainage slopes. This slab overlay
should be 3 1/3" thick at the edge and rise to 5"thick near the center to obtain a 1%slope to better drain the
surface. This overlay would have a single mat of bar reinforcement and fiber to reduce cracking. The stairs
would need to be replaced with new concrete stairs with a 12"tread and lower 6" to 7" riser. The perimeter and
stair railing and fence gate posts are in good condition and could be removed and reinstalled. There is
approximately 990 square feet of floor and wall top that would receive the overlay.
Repair costs are estimated as follows:
ITEM QUANTITY UNIT PRICE COST
Pier concrete repair 36 SF $250 $9,000
Cofferdam for pier 1 EA $3,000 $3,000
Concrete overlay of floor slab 990 SF $60 $59,400
Stairs 1 EA $2,500 $2,500
Remove and reinstall railing and gate 120 LF $40 $4,800
Subtotal $78,700
Engineering design and construction services $21,300
Total project cost $100,000
As stated in the directive letter from the DNR, these maintenance repairs typically would not require a permit
from agencies other than an approval by the DNR Dam Safety staff.
Please let me know if you need additional information or have questions.

Township 29 North,Range 20 West, Section 23, City of Hudson, St. Croix County,Wisconsin.
Dear Mr.Peters:
Thank you for your cooperation with the Department's required dam safety inspections. We have reviewed the
inspection report prepared by Philip Caswell P.E. of Stantec Consulting Services Inc.which was submitted to the
Department of Natural Resources on November 18,2015. The report and recommendations meet the
requirements of Ch. 31.19, Wis. Statutes for owner-responsible inspections of large dams. The report included
specific recommendations for the dam.
The Lower Power Dam is a large, low hazard dam,which discharges directly into the St. Croix River. The current
Emergency Action Plan(EAP) and Inspection, Operation, and Maintenance Plan(IOMP), dated December 2014,
were approved on January 6,2016. The minimum and normal water levels for Lake Mallalieu were permitted in
1983,which are 688.45 ft. and 688.95 ft.respectively. The Lower Power Dam is approximately 22 ft. in structural
height and impounds a maximum of 3000 acre-ft.
The inspection report includes timeframes for addressing the deficiencies and improving the safety and structural
integrity of the dam. We have modified the recommended timeframes below in our directives to you to make
repairs to bring the dam into compliance with the code.
DIRECTIVES DATE DUE
1. Concrete Repair January 6,2018
i
The 2012 inspection reported indicated concrete spalling was observed at the water line of the pier between tainter
gates#2 and#3 (numbered right to left, looking downstream). The extent of the spalling is such that the steel
reinforcing bars are exposed.Additional investigation of the remaining piers and abutments should be completed
and the repairs as needed. The repairs of the piers, as long as they are replacement in kind,would be a
maintenance item,however please submit plans and specifications to the Department for approval.
2.Powerhouse January 6,2018
According to the inspection report,the floor/deck of the decommissioned Powerhouse has signs of heavy
efflorescence, due to water absorption. Sounding was completed with a hammer, and extensive delamination of
the surface concrete was detected. The existing floor/deck of the Powerhouse should be replaced and designed to
drain properly to avoid ponding.Please submit plans and specifications to the Department for review and
approval.

3.Erosion September 6,2016
Two areas of surface erosion were noted near the main dam; one approximately 120 ft.North of the dam and the
other 120 ft. South. The areas of erosion should be filled with a clay-like soil, compacted and reseeded to armor
the embankment of the dam.
4.Vegetation September 6,2016
Significant vegetation was noted north of the main dam and at secondary dam near the existing bridge and
abutments. Continue to routinely maintain and remove any vegetation in all pertinent areas of the dam structure.
As highlighted in the inspection report,please remove larger vegetation with caution, as to not weaken the
embankment. Fill,compact, and re-seed any areas that are impacted by removal.
If you are unable to meet the schedule for the completing the directives listed above,please submit a revised
schedule to the Department by February 6,2016.If we do not hear from you by then,the schedule listed above
will be in effect.If the schedules are not met,the Department may have to consider other alternatives to ensure the
safety of the dam is maintained.
This concurrence letter contains a sufficiency rating based on Departmental guidance dated September 18,2012.
The rating is only intended to reflect the Department's interpretation of the physical conditions on the day of the
inspection outlined in the report prepared by your consultant. The rating is not required by State Statute and does
not imply any regulatory significance. The rating is not a Departmental certification of the overall safety,
structural adequacy,hydraulic capacity or operation of the dam during any loading conditions. Departmental staff
has been requested to assign sufficiency ratings to be in compliance with Federal grant requirements for the State
Dam Safety Program. The Lower Power Dam has a sufficiency rating of Satisfactory.
If you have any questions concerning this letter or the operation and maintenance of your dam, or you are
uncertain how to proceed with the directives above,please contact me at Michael.Ro ng_eydwwisconsin.gov or 715-
839-3735.
