Aquatic Invasive Species Awareness Week

DNR, DEQ, MDARD to host outreach events at boat launches during Aquatic Invasive Species Awareness Week
Gov. Rick Snyder has proclaimed July 3-9 as Aquatic Invasive Species Awareness Week in Michigan, and state departments are observing the week with outreach events at more than 50 boat launches statewide.

AIS are non-native aquatic plants and animals that disrupt the natural ecosystem, tourism and the economy.

The week is highlighted by the third annual AIS Landing Blitz, an outreach event for boaters held at boat landings around the state. The DEQ is partnering with local volunteers as well as the Department of Natural Resources and Department of Agriculture and Rural Development to assist boaters in preventing the spread of these harmful species and complying with current AIS-related laws.

With recent discoveries of invasive New Zealand mudsnails in the Au Sable and Pere Marquette rivers, the week takes on an added importance. Many invasive species, including New Zealand mudsnails, are easily spread by boaters and anglers using their equipment in multiple bodies of water without properly cleaning it.

Anyone enjoying Michigan’s waters can take action to prevent the spread of aquatic invasive species by following these simple steps:

Required Actions – It’s the Law in Michigan!
• Remove aquatic plants from boats, boating equipment and boat trailers before launching or placing in the water.
• Drain live wells, bilges and all water from boats before leaving the access site.
• Dispose of unused bait in the trash. Do not release bait into the water.
• Don’t transfer fish to water bodies other than where they were caught.
Recommended Actions – Protect Our Waters!
• Inspect and remove plants and mud from boats and trailers and dry equipment before leaving the access area. Dispose of the material in a trash receptacle or otherwise away from the water body if possible.
• Wash boats and trailers before leaving the access area if possible, or at a nearby car wash or at home.
• Dry boats and equipment for at least five days before launching into a different body of water.
• Disinfect live wells and bilges with bleach solution of 1/2 cup bleach to 5 gallons of water.
The Great Lakes and Michigan’s inland waters draw millions of recreational users and tourists annually, and already face negative impacts from numerous aquatic invasive species. Preventing the introduction of further invasive species is a responsibility for everyone who uses these resources.

AIS Awareness Week is sponsored by the DEQ’s Water Resources Division with collaborative efforts from other state and federal agencies as well as private and nonprofit organizations.

“Of Mosquitoes and Killer Bees”

Condensed from a Michigan Lake and Stream website article (Click Here For Whole Article)

Property owners in Michigan during the 1960's and 1970's main safety problem on inland lakes was speed boats operated in fast or unsafe fashion. During the 1980's the proliferation of jet skis or personal watercraft struck many riparians as nuisance and a safety hazard. Today, riparians are
becoming increasingly concerned about the popularity of “wave boats” (also sometimes referred to as bladder boats, wave runner boats or wake board boats). Unfortunately, the impact of wave boats on Michigan inland lakes appears to be dramatically worse than the negative consequences of personal
watercraft and conventional speed boats. Speed boats are bumble bees, while wave boats are killer bees! (thus the title of the article) 

What is a wave boat? It is a watercraft that uses mechanical means to fill reservoirs (sometimes called “bladder”) with water or other liquid to increase the boat's weight and mass, and to raise or lower the boat in the water. Depending upon how a wave boat is operated, it can throw a tremendous wake and create huge artificial waves.

There are three major concerns regarding the use of wave boats in inland lakes. First, on many lakes, they have had severe negative environmental impacts. If one of the purposes of a wave boat is to create huge waves, that goal has proven all too successful! On some lakes, wave boats have caused
considerable erosion along the shoreline and banks of the lake. Wave boats also keep the water “churned up”, particularly in shallower areas, thus disturbing plant life, fish, aquatic insects and other natural lake organisms. 

The second negative impact of wave boats is property destruction. Riparians
throughout the state have reported instances of moored boats being swamped, boat tether lines snapped, adjoining anchored boats being slammed into each other and similar property destruction caused by the
huge waves generated by wave boats. 

The third and final problem associated with wave boats involve safety. There have been reports throughout Michigan of people being thrown off swim rafts and even other boats due to the waves generated by the wave boat passing too close. The risk for bodily injury associated with wave boats passing too close is obvious. It is likely that the most practical way of minimizing the adverse impacts of wave boats is to vigorously enforce state boating laws. Any type of motor or power boat operated at greater than a slow or nowake speed must remain at least 100 ft. away from the shore, a dock or swim raft, a marked swim area, a swimmer or an anchored vessel. Both careless and reckless use of a watercraft are illegal.

Some owners of wave boats argue that it is not fair to “profile” or “discriminate against” a particular type of watercraft. However, it cannot be denied that the impacts of wave boats on inland lakes can be much more severe than conventional speed boats. Problems associated with wave boats are different
from other watercraft, not only in kind but also in magnitude and intensity.

DEQ Permit Issued - Devils Lake Ventures
The original request by Devils Lake Ventures was for 168 boat slips for the marina at the old Sun and Snow location. Forty slips were to be reserved for the restaurant with 128 slips for rental. The plan was to roll this out over 5 years with fewer slips to start and add some each year as market dictates, to the full 168 in the last year assuming the need is there.

December 15, 2015, Permit WRP001160 was issued to construct a 114 slip marina with two main docks.  To view a copy of the permit with attached plans, Click Here

Microbeads, tiny plastic particles, often less than a millimeter in size, are packed into personal hygiene products. Being so tiny, they pass through wastewater treatment systems and end up in rivers, lakes and oceans. Read More... 

What is the Best Lawn Fertilizer?

In an effort to protect water quality in the area we are asking all residents to consider using no-phosphorous lawn fertilizer.  It is estimated that just one pound of phosphorous in the water will produce 500 pounds of blue-green algae. Much of the phosphorus you apply actually runs off the lawn before penetrating the soil. That means that it gets into the lakes and streams contributing to the glue-green algae bloom and the growth of other aquatic plants. Blue-green algae not only stinks but can be toxic to animals and children. When the algae bloom decays, it reduces the oxygen in the water and can cause fish kills. Phosphorus run-off from feed lots, agricultural land and lawns is the main contributor to phosphorus in lakes. The best time to fertilize is May and early June (now). Your lawn does not need phosphorus! Unless you have a newly seeded lawn most soil provides all the phosphorus your established lawn needs.

Bait Dumping Concerns

From the AP John Flesher August 28th, 2014:

“Inadequate regulation of the bait-fish trade and carelessness on the part of anglers may be allowing invasive species – including the feared Asian carp – to reach Great Lakes and inland waterways, according to a scientific paper.”

There is more to this story (Click to read entire article...), but it ultimately comes down to “what can we do?” The answer is …DON’T DUMP LEFTOVER BAIT INTO THE LAKE!!! The LPL has been putting reminders on windshields of cars parked at the public ramp, and plans to post this reminder there for all to see.

A Landmark Remembered

The Clearwater Beach Association of Devils Lake recently placed a plaque on what remains of the Clearwater Beach Arch.

The arch was built in 1928 and placed on the Michigan State Register of Historic Places in 1984.
