Weed Treatment

Crystal Lake will be treated for Eurasian Milfoil in 2017. It usually takes two weeks minimum to see results of this application. This treatment will attack specific spots where the plant has returned and will not be an entire lake application

The 2,4-D is a growth hormone mimic, meaning that it causes susceptible plants to grow faster than usual and otherwise disrupts normal growth processes such as membrane protein synthesis, RNA production, and overall stability and integrity of plasma membranes. Typically you see a flush of growth first, often times curled/twisting (epinasty) on the new growth where the hormones work, and then a browning and withering from 2-3 weeks after treatment because the increased cell proliferation increases and the plant's vascular system becomes blocked due to excessive cell division and the resulting growth crushes the vascular transport system. Basically the plants grow so fast that the support structures and transport systems cannot be made fast enough to keep the plant together.

Restrictions are no swimming in treated or adjacent areas for 24 hours from application. No water to be used for drinking or irrigation for 21 days. No restrictions on fishing.

5-Year Management Plan

The upcoming application to control Eurasian Milfoil weeds and other costs are expensive. By becoming e a CLAA member you will help support your community. Please consider becoming a Crystal Club member.  The additional $70 (or $6 per month) will go a long way this year to conquer the weeds and remain within our budget.

Eurasian Watermilfoil Information

A Eurasian Watermilfoil manual removal instructional video is now available for public viewing on YouTube. Specialists talks about the proper techniques used to remove above-water and underwater milfoil by hand.

Pier Registration

Waterfront property owners with larger piers may need to register their piers with the DNR to ensure their piers will be "grandfathered" from new size limits adopted by the State of Wisconsin in 2004. Generally, a pier will need to be registered if it (a) is wider than 6 ft, but less than 8 ft in width, (b) has a platform at the end of the pier that has a surface area of less than 300 ft (w/ a max. width of 10 feet) and/or (c) more than 2 boat slips for the first 50 feet of shoreline frontage and 1 boat slip for each additional 50 feet of shoreline frontage. To register a pier, a waterfront property owner must complete and mail a registration form to the DNR. Learn more.

Swimmers Itch

“Swimmers Itch” occurs within several hours of leaving the water. It is neither dangerous nor contagious, but is very uncomfortable. Children have the highest risk, since they tend to play in shallow water and are less likely to dry off with a towel. Swimmer's itch is caused by the larvae (immature stage) of certain flatworms that can be picked up while swimming. Technically it is known as schistosome dermatitis. When the larva penetrates the skin, it causes a small red welt. The degree of discomfort and bodily reaction varies with the person's sensitivity and the degree of infestation. In some people, the reaction may be hardly noticeable. Others have considerable pain, fever, severe itching, and swelling. The swelling usually subsides within a week, but the redness can last longer.

When Risk Is High
Swimmer's itch organisms are most commonly noticed in the summer, when the water is its warmest. The season is relatively short - usually four to six weeks, depending on the weather. This usually occurs in late June or early July in the midwest, coinciding with peak water recreational activities. At this time the organism can accidentally contact bathers and cause swimmer’s itch. In years of warm spring weather, swimmer’s itch has occurred as early as May.

Preventing Swimmer's Itch
Feeding ducks should be discouraged if swimmer’s itch is known to be a problem on the lake, since waterfowl are an important adult host to the parasite. New occurrences of swimmer’s itch seem to be strongly associated with people feeding and attracting ducks. Some people have noted that waterproof sunscreens and lotions reduce the infections. If you decide to go in the water when and where swimmer's itch larvae are present, stay clear of plants growing in the lake. Swimming rather than playing or wading in shallow water will reduce exposure. The most important thing to do to prevent the itch is to rub down very briskly with a towel right after leaving the water. This can crush the organisms before they can penetrate the skin. Showering shortly after leaving the water also should help.

Easing Swimmer's Itch
After the swimmer's itch organisms have penetrated the skin, there is little that can be done to treat it. You may get some relief by using soothing lotions such as calamine or lotions containing antihistamines and/or local anesthetics. Talk to your doctor if you have a rash after swimming that lasts more than one week or if you notice pus at the rash site. Swimmer's itch rarely leads to complications, but infection is possible if you scratch the rash too harshly.

Poison Ivy

The following WebMD website will be helpful if you get poison ivy, or have questions on what it looks like, etc.

Bow Fishing for Carp

If you see someone using a generator and going around the lake edges at night shinning 5 or 6 lights toward the shore what they are doing is bow fishing for carp at night. Carp is considered a rough fish and detrimental to aquatic ecosystems. The floodlights illuminate the shallow waters and carp which explains the boat going around the shorelines. Night bow fishing is a successful means of harvesting carp. The very bright floodlights reflect off the lake surface and shine on houses. The floodlights are however not aimed directly at the lake homes but is actually the light reflecting. For more information on bow fishing in Wisconsin visit the Wisconsin Bow Fishing Association website. The Plymouth DNR service station number is (920) 892-8756. Below is a direct copy of text from the Wisconsin DNR Netting and Spearing Regulations.

Spearing and Netting Regulations 2010-2011
FISHING WITH BOW AND ARROW YOU MAY NOT:
Take rough fish with a bow and arrow unless the arrow is equipped with a metal barbed tip that is attached to the bow with a tethered line that allows for the retrieval of the arrow and the fish. Release or return any rough fish taken with a bow and arrow, whether dead or alive, to any waters of the state. Leave any rough fish taken with a bow and arrow, whether dead or alive, on the ice or banks of any waters of the state. Violate local ordinances that prohibit the discharge of bow and arrow within their area of jurisdiction. Check for local ordinances on the use of bow and arrow within city, town, or village limits. LEGAL HOURS: On all inland, outlying, and boundary waters with an open season for spearing rough fish, the taking of rough fish with a bow and arrow on that body of water is allowed at any time of day, including from sunset to sunrise during that open season.
