Aquatic Invasive Species Update 
Washington & Waukesha Counties
December 2017

We hope you have a happy, safe, and invasive free Holiday!

Clean Boats, Clean Waters in 2017 Recap

It has been a banner year in Washington and Waukesha Counties for  Clean Boats, Clean Waters. Together both counties inspected 5,945 boats talking to a grand total of 12,183 people. Every single contact was a fantastic teaching opportunity! 

There were some really great moments out at the launches this summer. Particularly seeing waterfowl hunters make the connection that mud on their decoys and dogs has the ability to spread AIS and take efforts to avoid the spread.

Seeing the amazement in a youngster's reaction as they see how small a zebra mussel really can be, or educating a fisherman about adventitious roots of Eurasian water milfoil made for a good day. In this area, you can feel the difference that's been made by all the wonderful volunteer efforts over the summer. By the end of the season it is common to see boaters look at their trailers and even use the tools from the cleaning stations to remove vegetation.

A HUGE thank you to all of the volunteers, security staff, Lake District and Association staff, and boaters for getting out and having these important discussions.

Grants for CBCW inspections next summer were due December 10th. We have had a lot of calls about applying for Grants in both Counties this year, and are hopeful to continue this positive trend next year.
Strategic Plan Update
Waukesha County staff has been working hard to develop an Aquatic Invasive Species Strategic Plan and are preparing to release it soon. The plan will contain valuable information and maps for boaters and water users of all kinds to successfully prevent the spread of invasive species among county water bodies! 

The project charter states: by January 2018, complete a Waukesha County Aquatic Invasive Species (AIS) Strategic Plan for citizens to use as a reference to AIS presence in lakes, guidance in lake management, and a tool for best management practices. 

The AIS Strategic Planning Committee discusses the Plan


The Plan will clarify what defines an aquatic invasive species, as well as some background to the AIS program in Waukesha County.

An interactive map will allow users to filter their search to see AIS that have been surveyed at points in their lake of interest. The map will also link to photos of every launch in the County, so visitors can get an idea of what parking lots look like at each launch and plan accordingly. There are also photos of signs at launches displaying ordinances for each lake.

Each aquatic invasive species will have a smaller county map showing in which lakes it is located. The species of plants and animals found in Waukesha County will be described so anyone who thinks they have found an invasive species can use this tool as a reference. The plan will have recommendations for how to control aquatic invasive species if found.

The new AIS Mapping Tool can filter out AIS by year and species and is based off the latest Point-Intercept surveys.
Strategic goals will be simply outlined with implementation dates, safe and effective control methods and a discussion of past successful treatment methods.
The goal is to send a web link to the final plan in the January Edition, stay tuned!
Lake of the Month - Lake Denoon
December's lake of the month is Lake Denoon in the City of Muskego (see map).  Lake Denoon is a 167 acre lake located in SE Waukesha County. It has a maximum depth of 55 feet. Fish include Panfish, Largemouth Bass, Northern Pike and Walleye. The lake's water clarity is low. The lake actually extends partially the Town of Norway in Racine County. 

 On December 19th, Lake Denoon was approved by the Waukesha County Board as the 20th Lake District in the County. It is a very exciting opportunity for the new District to grow as lake stewards and take care of their water. 

One of the main reasons Lake Denoon Lake District (LDLD) formed was to prevent the spread of invasive species to and from their Lake. They have seen the detrimental effects of zebra mussels and Eurasian water milfoil and wanted to protect their lake against threats of other AIS, like starry stonewort, from neighboring lakes. What a fantastic way to heed to the call of the incoming threat of AIS. 

Lake Denoon is the 20th Lake District in the County.

County staff look forward to having  Clean Boats, Clean Waters watercraft conversations with the LDLD board in the near future.

If you are looking to participate in AIS activities on your lake, feel free to contact the AIS team about getting involved.
