ZEBRA MUSSELS CONFIRMED IN COFFEY COUNTY LAKE

Zebra Mussel

EMPORIA – Officials with the Kansas Department of Wildlife, Parks and Tourism and the Wolf Creek Generating Station announced Friday that zebra mussels have been found in Coffey County Lake. Officials knew it was a matter of time before zebra mussels appeared in the lake near Burlington because the aquatic nuisance species (ANS) had been detected in Marion Reservoir three years ago. The Cottonwood River flows from Marion Reservoir into the Neosho River, which then fills John Redmond Reservoir. Coffey County Lake, which is the cooling lake for Kansas’ only nuclear power plant, gets its water from John Redmond. The larval stage of zebra mussels, called veligers, are microscopic and free-floating in water. Transmission downstream from an established population is the only method of spreading zebra mussels that is inevitable.


Wolf Creek officials were prepared for this event and have implemented procedures and equipment to ensure that zebra mussels won’t interfere with the generating station’s operations.


Zebra mussels are small, bi-valve mollusks with striped shells. They are native to the Black and Caspian seas of Western Asia and Eastern Europe and have been spread across the world via shipping. They were discovered in Lake St. Clair and the Detroit River in 1988. Zebra mussels quickly spread through out the Great Lakes and to many inland rivers including the Mississippi, Illinois, Ohio, Tennessee, Arkansas and Hudson. They first appeared in Kansas in 2003 when they were discovered in El Dorado Reservoir. Public education programs were designed to inform boaters about the dangers of zebra mussels in our waters and ways to prevent spreading them. However, zebra mussels have been confirmed in more the a dozen Kansas lakes in the past nine years. Moving water in boats and bait buckets was identified as a likely vector and recently, KDWPT established stringent regulations regarding the use of wild-caught bait, as well as prohibiting the movement of live fish from lakes where zebra mussels have been found.


Although related, zebra mussels differ from our native mussels in several important categories. Perhaps the most important is their ability to produce very large populations in a short time. Unlike native mussels, zebra mussels do not require a host fish to reproduce. A large female zebra mussel is capable of producing 1 million eggs during the reproductive season. Once fertilized, eggs develop into microscopic veligers. These veligers cannot be seen by the naked eye and can be contained by the thousands in very small quantities of water. Veligers passively float within the water for up to two weeks before they settle out as young mussels. These young mussels quickly grow to adult size and reproduce during their first summer of life, thus adding to the problem of extremely dense populations.


After settling, zebra mussels develop byssal threads that allow the shells to attach to hard surfaces such as rocks, piers, and flooded timber. They also attach themselves to pipes, water intake structures, boat hulls, propellers, and lower units of out board motors. As populations continue to increase in these areas, they can clog intake pipes and prevent water treatment plants and electrical generating plants from drawing water. In 2012, two Kansas communities, Council Grove and Osage City, experienced water shortages because of zebra mussel infestations before water intake structures could be cleaned up. Removing large quantities of zebra mussels to ensure adequate water supplies can be labor-intensive and costly.


Zebra mussels are just one of the non-native aquatic species that threaten our waters and native wildlife. Boaters and anglers are reminded to follow basic precautions to stop the spread:

• Clean, drain and dry boats and equipment between uses

• Wild-caught bait may only be used in the lake or pool where it was caught

• Live fish may not be moved from waters infested with zebra mussels or other aquatic nuisance species

• Livewells and bilges must be drained and drain plugs removed from all vessels prior to transport from any Kansas water on a public highway

Milford Reservoir upgraded to “Warning,” Marion Reservoir taken off lists
TOPEKA — Recent testing of Kansas lakes by the Kansas Department of Health and Environment (KDHE) has revealed a number of changes in blue-green algae levels in the state’s lakes. Samples collected at Milford Reservoir in Clay, Geary, and Dickinson counties indicate that levels of algae and toxins have increased, so the lake’s status has been upgraded from “Advisory” to “Warning.” Logan City Lake in Phillips County has also been upgraded from Advisory to Warning.

Marion Reservoir, which was previously under an Advisory, has been taken off all listings for blue-green algae. Dillon Park Lake, Harvey County Camp Hawk Lake, and Rigg’s Park Lake in Haysville have been downgraded from Warning to Advisory.

Based upon the latest sampling results and established health risk levels, KDHE issues Warnings and Advisories. A “Warning” is issued when high levels of toxic blue-green algae have been detected. A “Public Health Warning” indicates that water conditions are unsafe, and direct water contact (wading, skiing, and swimming) should not occur.

Blue-green algae do not affect the drinking water in state parks, and all campgrounds, marinas, and other lakeside businesses remain open for business.

KDHE samples recreational bodies of water for blue-green algae when the agency is alerted to a potential algae bloom. When harmful algae blooms are present, KDHE, in cooperation with the Kansas Department of Wildlife, Parks and Tourism, responds by informing the public of these conditions.

Health effects from exposure to blue-green algae can vary. The most common complaints after recreational exposure include vomiting, diarrhea, skin rashes, eye irritation and respiratory symptoms. These toxins also cause deaths in pets.

Current concentrations of algae in the following waters exceeded the KDHE recommended level of less than 100,000 cells/ml for recreational water use and are currently under Warning:

• Milford Reservoir — Clay, Geary and Dickinson counties (upgraded from Advisory);
• Logan City Lake — Phillips County (upgraded from Advisory)
• Augusta City Lake — Augusta, Butler County;
• Augusta Santa Fe Lake — Augusta, Butler County;
• Harvey County East Lake — Harvey County;
• Harvey County West Lake — Harvey County; and
• Memorial/Veterans Park Lake — Great Bend, Barton County.

When a Warning is issued, KDHE recommends the following precautions be taken:

• do not drink lake water;
• do not swim, wade, or do anything with full-body contact with lake water;
• clean fish well, consume only the fillet portion, and discard all other parts; and
• keep pets from having contact with or drinking lake water.

An “Advisory” is issued when harmful blue-green algae have been detected. A “Public Health Advisory” indicates that a hazardous condition exists, but water activities such as boating and fishing may be safe. However, direct contact with water (wading, swimming) is strongly discouraged for people and pets.

KDHE has issued an Advisory for the following Kansas public waters:

• Dillon Park Lake — Hutchinson, Reno County (downgraded from Warning);
• Harvey County Camp Hawk Lake (downgraded from Warning);
• Warnock Lake — Atchison County;
• Rigg’s Park Lake — Haysville, Sedgwick County (downgraded from Warning).

When a Advisory is issued, KDHE recommends the following precautions be taken:

• do not drink lake water;
• avoid swimming, wading, or other activities with full body contact with lake water;
• clean fish well, consume only the fillet portion, and discard all other parts; and
• keep pets from having contact with or drinking lake water.

KDHE will continue to monitor these public waters and will update statements as conditions warrant. More information on algae and algae blooms, including up-to-date advisories and Warnings, can be found at online at www.kdheks.gov/algae-illness/index.htm.

KDHE ISSUES NEW BLUE-GREEN ALGAE ALERTS

TOPEKA — Blue-green algae are natural, common bacteria in all waters of Kansas. Ordinarily, they are not harmful to humans or aquatic life, but under certain conditions — especially during the heat of the summer — they can multiply rapidly, resulting in a “bloom.” When this happens, blooms may release toxins that are dangerous to fish, pets, and humans. Some algae blooms look like foam or a thick slurry. They can be blue, bright green, brown, or red and may look like paint floating on the water. Some blooms may not affect the appearance of the water. Algae blooms should be considered Nature’s warning signs saying, “Stay out of the water.”
The Kansas Department of Health and Environment (KDHE) samples recreational bodies of water for blue-green algae when they are alerted to a potential algae bloom. When problems arise, they cooperate with the Kansas Department of Wildlife, Parks and Tourism (KDWPT) and federal officials to inform the public.
Based upon the latest sampling results and established health risk levels, KDHE is currently issuing warnings and advisories, and lake users should understand these two terms.
A “warning” is issued when high levels of toxic blue-green algae have been detected. A “Public Health Warning” indicates that water conditions are unsafe, and direct water contact (wading, skiing, and swimming) should be avoided. Current concentrations of algae in the following waters exceeded the KDHE recommended level of less than 100,000 cells/ml for recreational water use and are currently under warning:

• Milford Lake (new listing);
• Santa Fe Lake in Augusta (new listing);
• Marion County Lake;
• Memorial Park Lake, Great Bend, Barton County; and
• Meade State Lake, Meade County.

When a warning is issued, KDHE recommends the following precautions be taken:

• do not drink lake water;
• avoid swimming, wading, or other activities with full-body contact of lake water;
• clean fish well, consume only the fillet portion, and discard all other parts; and
• keep pets from having contact with or drinking lake water.

As a result of the warning at Milford Reservoir, the U.S. Army Corps of Engineers (USACE) and KDWPT have closed Military Marina Cove/Boat Ramp, Timber Creek Boat Ramp, Milford State Park Swim Beach, and Wakefield Boat Ramp Area/Swim Beach. Milford Reservoir is open, and the parks, marinas, and lakeside businesses around Milford Reservoir are open for business as usual, including camping and other recreational activities. The drinking water and showers are safe and not affected by the algae bloom.
An “advisory is issued when harmful blue-green algae have been detected. A “Public Health Advisory” indicates that a hazardous “condition” exists, but water activities such as boating and fishing may be safe. However, direct contact with water (wading, swimming) is strongly discouraged for people and pets.
KDHE has issue an advisory for the following Kansas public waters:

• Big Hill Reservoir, Labette County;
• Perry Reservoir (the entire lake), Jefferson County;
• Marion Reservoir, Marion County;
• Old Herington City Lake, Dickinson County; and
• Logan City Lake, Phillips County.

In addition, KDHE recommends the following precautions be taken:

• do not drink lake water;
• clean fish well, consume only the fillet portion, and discard all other parts; and
• keep pets from having contact with or drinking lake water.

Previous warnings for Perry Lake Rock Creek Arm and the Perry Lake Old Town Public Use Area on Perry Reservoir have been lifted. Perry Reservoir remains under an advisory status, but the lake and Perry Lake State Park Swim Beach have reopened.
KDHE will continue to monitor these public waters and will update statements as conditions warrant. More information on algae and algae blooms, including up-to-date advisories and warnings, can be found at online at www.kdheks.gov/algae-illness/index.htm.
