RE: Status of Sewer Connection
The following properties have not yet connected to the sewage system after given the 9-
month connection letter. June 9, 2017 was the deadline to connect sanitary sewer.
Here is the current status of each property.
2254.997 S90W13276 Boxhorn Dr.
The residents for this property have been invited to Public Works committee
meeting on 8/09/17.
2254.997 Walter & Eileen Hendrickson (414-546-2119). Per phone
conversations they have not hooked up because their son Eric is going to buy
the house and remodel and did not want to hook up if remodel was going to
change location. They are looking for an extension.
2254.997.002 S90W13232 Boxhorn Dr.
This property is own by the State of WI DNR. The existing house on this
property will be coming down.
2255.999.002 S90W13253 Boxhorn Dr.
An extension was given to 10/27/17 for hookup. Currently this property
owner’s plumber is working with City of Muskego engineering department to
properly size the grinder pump in his house to make their extension.
Recommendation:
If the Henderickson’s (2254.997 S90W13276 Boxhorn Dr. ) still desire an
extension, the City of Muskego would provide a 4 month extension from the date
of council approval. After this 4 month extension, the City of Muskego would
move forward with a forced hookup proceeding. (Refer to Chapter 21 Section
21.5)
No further action is required at this time with the following two properties.
• 2254.997.002 S90W13232 Boxhorn Dr.
• 2255.999.002 S90W13253 Boxhorn Dr.

Staff Report to Public Works Committee
To: Public Work Committee
From: Scott Kroeger, PE, PLS, Public Works and Development Director
Subject: Little Muskego Lake Drawdown
Date: August 21, 2017
The Little Muskego Lake has an invasive species called the Starry Stonewort. The WDNR
has determined in a lab that freezing the Starry Stonewort has been an effective way to kill
this invasive species. In order to control the Starry Stonewort in Little Muskego Lake, the
Little Muskego Lake District has asked the City of Muskego to fill out an application with
the WDNR to drawdown Little Muskego Lake by 7 feet. The City of Muskego filled out an
application to WDNR on May 5, 2017.
The WDNR went through their approval process for the City of Muskego’s application and
issued their approval on August 1, 2017. The drawdown needs to start on September 5,
2017 and end on October 1, 2017. The drawdown approval letter comes with 9 conditions.
The City of Muskego owns and operates the Little Muskego Lake Dam and has the final
decision on whether to move forward or not with this drawdown.
Attachments
Attachment A: The drawdown application
Attachment B: The WDNR approval letter with conditions
Attachment C: WDNR Information on the Little Muskego Lake drawdown
Recommendation for Action by the Committee:
City of Muskego staff recommends this item be thoroughly discussed at the public works
committee and due to the importance of this decision it should be deferred to Common
Council for approval or disapproval on Tuesday August 22, 2017. A WDNR representative
will be present at Common Council for questions.
The City of Muskego staff does not have a recommendation to the Public Works committee
or Common Council on this action. However, if the Common Council does decide to move
forward with this drawdown we have a list of recommendations.
1. The Little Muskego Lake District needs to provide a plan providing all the
communication and coordination necessary to City of Muskego, residents, general
public, etc. about getting all required boats and piers removed from Little Muskego
Lake before or shortly after the September 5, 2017 drawdown begins. The City of
Muskego staff does not have time or staff required for this coordination. The City of
Muskego can’t take on any liability with regards to this coordination.
2. The list of the WDNR’s conditions and limitations required with this drawdown will
require a number of City of Muskego staff and hours on a daily basis that was never
budgeted for in 2017. The recommendation would be to have the Little Muskego Lake
District pay for City of Muskego staff under a time and material contract. There is no
way the City of Muskego can budget properly for all the conditions and limitations set
forth in their approval letter.
3. As part of the WDNR’s conditions and limitations, the City of Muskego must monitor
the downstream area for flooding and sediment transport. The City of Muskego will
properly document the existing conditions of the downstream area and the post
conditions of the downstream area. If there requires any type of restoration, dredging,
etc. along the downstream area due to this drawdown it will be paid for by the Little
Muskego Lake District. The City of Muskego does not have the budget for any of this
work.
4. Any and all work related to the drawdown is at the sole request of the Little Muskego
Lake District. It is the recommendation of City staff that the Little Muskego District
Lake provide a Letter of Credit or deposit in an estimated amount of all costs to be paid
herein.

APPROVAL
The City of Muskego is hereby granted under Section 31.02(1), Wisconsin Statutes, approval to draw
down the Little Muskego Dam on Muskego Creek, in the City of Muskego, Waukesha County. The
applicant is bound by any conditions of this approval.
CONDITIONS
1. The controlled drawdown will be completed by October 1, 2017 or before the water temperatures go
below 55 degrees Fahrenheit. To use this option, the applicant would have to measure water
temperatures in Little Muskego within the impoundment. The drawdown must be completed before
water temperatures drop below 55 degrees Fahrenheit in the impoundment. If this is the preferred
option the applicant will need to identify the monitoring locations in the impoundment; record
the date, time, and temperatures; and submit the information to Michelle Hase with the
Department prior to the drawdown and periodically during the drawdown.
2. If the full 7-foot drawdown is not complete by October 1, 2017, the City will need to contact Michelle
Hase of the DNR to determine if conditions will allow for the drawdown to continue. The Department
will inform the City when the drawdown will need to be discontinued and the impoundment may not
be drawn down further than that level.
3. The water level may be drawn down no faster than 4-inches per day (24-hour period) for the first 3
feet of drawdown. The water level may be drawn down no faster than 6-inches per day (24-hour
period) for the remaining 4 feet of drawdown.
4. The impoundment shall be refilled by ice-out conditions. The rate of refill shall not exceed 6-inches
per day (24-hour period).
5. The City must pass minimum flow at all times during the extent of the drawdown and refill of the
impoundment.
6. The City must monitor the downstream area for flooding and sediment transport. The drawdown may
not continue if downstream levels exceed bank full conditions.
7. The drawdown may not begin or continue until the following dams are within their normal operating
range: Big Muskego, Wind Lake, Rochester, and Waterford.
8. The drawdown may not begin until the USGS gages for the Fox River at New Munster is below flood
stage.
9. The City must inform the following entities of drawdown status and operation at a minimum of a bi -
weekly basis: Department of Natural Resources, Wind Lake Management District, Racine County,
Racine County Drainage District, Town of Norway.
FINDINGS OF FACT
1. The City of Muskego submitted to the Department a temporary drawdown request form for the Little
Muskego Dam on May 2, 2017.
2. The Little Muskego Dam is owned and operated by the City of Muskego.
3. The impoundment will begin being drawn down on September 5, 2017 and will be completed by
October 1, 2017. The impoundment will be refilled when ice-out conditions exist on the lake.
4. The impoundment will be drawn down by 7 feet to an elevation of 784.8 feet NGVD29 or as near to 7
feet as conditions allow.
CONCLUSIONS OF LAW
1. The Department has authority under Section 31.02, Wisconsin Statutes, and the foregoing Findings
of Fact, to issue an order granting the drawdown requested.
2. The Department has complied with Section 1.11, Wisconsin Statutes and NR 150, Wisconsin
Administrative Code.

Frequently Asked Questions – Little Muskego Drawdown and
Chapter 30 for Landowners – July 26th, 2017
What are our dredging options during the Little Muskego Drawdown? Are there any
exemptions? Can I remove any material without a permit? We heard there was an exemption
for 50 cubic yards.
There is no exemption for 50 cubic yards.
The dredging exemption is for manual dredging, which means dredging by hand or using a hand-
held device without the aid of external or auxiliary power. More information on the manual
dredging exemption is available here:
http://dnr.wi.gov/topic/waterways/documents/permitExemptionChecklists/14-
manualDredging.pdf
DNR also has a new Small Scale Dredging Permit, which allows for the removal of 25 cubic yards
over 5 years. Landowners would have to comply with the conditions of the checklist.
http://dnr.wi.gov/news/Weekly/Article/?id=3995
http://dnr.wi.gov/topic/Waterways/documents/PermitDocs/GPs/GP17.pdf
Larger scale dredging permits need to follow the process outlined on this link:
http://dnr.wi.gov/topic/Waterways/construction/dredging.html
Do you have a list of contractors that can do shoreline work?
The Department does not generally recommend contractors.
Can we remove trash from the exposed bed? Can we remove material such as broken glass?
If the removal of the material is by hand, the manual dredging exemption would apply if less
than two cubic yards. If the removal is not by hand, it would fall under the conditions of a
dredging permit.
Can we use this opportunity to add pea gravel?
Riparian owners can place pea gravel above the ordinary high water mark; below the ordinary
high water mark a permit is required. For more information, see this website:
http://dnr.wi.gov/topic/Waterways/recreation/pea_gravel.html
Can we remove large boulders/rocks?
Yes, if done by hand. If any machinery is needed, it would fall under the conditions of a
dredging permit. If less than 25 cubic yards, it may qualify for a small scale dredging permit.
Can I replace or repair my rip rap?
DNR has a general permit for rip rap repair:
http://dnr.wi.gov/topic/waterways/documents/PermitDocs/GPs/GP-RiprapRepair.pdf
If a riparian wants to repair rip rap on their property and they don’t meet the conditions
necessary to get the general permit, they can apply for an individual permit.
http://dnr.wi.gov/topic/Waterways/shoreline/lake_erosion.html
https://permits.dnr.wi.gov/water/SitePages/Waterway%20and%20Wetland%20Permit.aspx
If a riparian wants to replace their rip rap entirely, they may qualify for an exemption from
permitting. For more information on that, see the exemption checklist below. If the riparian
does not qualify for the exemption, they can apply for a permit.
http://dnr.wi.gov/topic/waterways/documents/permitExemptionChecklists/08-
riprapReplacement.pdf
Can I put in new rip rap? If not, what are other options other than rip rap for shore
stabilization? What if I need rip rap to protect from man-made waves (boat traffic)?
DNR has a general permit for the placement of new rip rap. Riparians should see the
checklist to see if they meet the conditions.
Otherwise, biological shore erosion control is a good option for shore stabilization. These
activities are exempt from permitting, provided they meet the conditions of the exemption
checklist.
