The Kansas Department of Health and Environment (KDHE) and the Kansas Department of Wildlife and Parks (KDWP) have issued a public health advisory due to blue-green algae.

A harmful algal bloom (HAB) may look like foam, scum or paint floating on the water and be colored blue, bright green, brown or red. Blooms can develop rapidly; if the water appears suspicious or there is decaying algae on the shore, avoid contact and keep pets away. These toxins can be absorbed by ingestion, inhalation of aerosols and even skin contact. Symptoms vary depending upon the type of exposure (e.g. direct contact, ingestion, inhalation) but can include rash, vomiting, diarrhea, fever, sore throat, and headache. If you, or your pets, come into contact with algae rinse the area with clean, fresh water. Suspected HAB-related health incidents, whether human or animal, regardless of season, should be reported at kdhe.ks.gov/1163.

Active Advisories

Warning

• King Lake, Lyon County
• Marion Lake (Reservoir), Marion County
• Rooks Co. SFL, Rooks County
• Webster Lake, Rooks County

Watch

• Eagle Lake (Bel Aire), Sedgwick County (Added June 28)
• Harvey County East Lake, Harvey County
• Lake Shawnee, Shawnee County
• Lovewell Lake, Jewell County
• Woodland Park Pond (Mount Hope), Sedgwick County

A Hazard status indicates that a harmful algal bloom is present, and extreme conditions exist.

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

• Signage should be posted at all public access locations.
• It is recommended that either a portion of the lake or the entire lake or zone, be closed to the public.
• In some cases, the adjacent land should be closed as well. Actual setback distances will be determined on a site-specific basis, if necessary.
• When partial closures (i.e., beach or cove) are issued, the remaining lake or zone area will carry a warning status.

A Warning status indicates that conditions are unsafe for human and pet exposure. Contact with the waterbody should be avoided.

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

• Signage should be posted at all public access locations.
• Inhalation of spray or aerosols may be harmful.
• Lake water is not safe to drink for pets or livestock.
• Lake water, regardless of blue-green algae status, should never be consumed by humans.
• Water contact should be avoided.
• Fish may be eaten if they are rinsed with clean water and only the fillet portion is consumed, while all other parts are discarded.
• Do not allow pets to eat dried algae.
• If lake water contacts skin, wash with clean water as soon as possible.
• Avoid areas of visible algae accumulation.

A Watch status means that blue-green algae have been detected and a harmful algal bloom is present or likely to develop. People are encouraged to avoid areas of algae accumulation and keep pets and livestock away from the water.

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

• Signage should be posted at all public access locations.
• Water may be unsafe for humans/animals.
• Avoid areas of algae accumulation and do not let people/pets eat dried algae or drink contaminated water.
• Swimming, wading, skiing and jet skiing are discouraged near visible blooms.
• Boating and fishing are safe. However, inhalation of the spray may affect some individuals. Avoid direct contact with water, and wash with clean water after any contact.
• Clean fish thoroughly with potable water and eat fillet portion only.

Advisories are Lifted when cell densities and toxin concentrations dissipate to levels below the Watch thresholds.

KDHE investigates publicly accessible bodies of water for blue-green algae when the agency receives reports of potential algae blooms in Kansas lakes. Based on credible field observation and sampling results, KDHE reports on potentially harmful conditions.

If you observe a scum or paint-like surface on the water, small floating blue-green clumps or filaments in the water, or if the water is an opaque green, avoid contact and keep pets away. These are indications that a harmful bloom may be present. Pet owners should be aware that animals that swim in or drink water affected by a harmful algal bloom or eat dried algae along the shore may become seriously ill or die.

Do you have spots in your lawn?  Hopefully not, but if you do there is an answer to at least one of the causes of lawn spots.  Dollar spot is a common problem on all turfgrasses grown in Kansas, including Kentucky bluegrass, tall fescue, perennial ryegrass, bentgrass, buffalograss, bermudagrass, and zoysiagrass. The disease may occur regardless of management or soil fertility, although damage usually is most severe if there is a deficiency of nitrogen. Dollar spot results in the formation of small, roughly circular, bleached patches in the lawn. The patches are more numerous in areas where there is poor air circulation or drainage. Most spots are only a few inches in diameter; however, under favorable environmental conditions and mowing heights greater than two inches, individual spots may exceed 6 inches in diameter. Affected plants within the diseased spots wilt and eventually turn tan or brown. During outbreaks of the disease, numerous spots on the turfgrass coalesce into large irregular dead areas. This can result in substantial damage to the turfgrass.

On individual infected plants, leaves develop light yellow to tan lesions with reddish-brown borders. On cool-season grasses, such as tall fescue and Kentucky bluegrass, lesions normally are located near the middle of the leaf and extend completely across the leaf blade. The bleached area is bordered by dark red to brown margins or lines, which are characteristic of dollar spot. On warm-season grasses (bermudagrass, buffalograss, and zoysiagrass) the bleached zones on leaves may be more numerous and smaller but are still bordered by brown bands. In the early morning when dew is still present on the turfgrass, small cottony strings of the fungus can sometimes be seen growing from the diseased leaf blades. This growth can be confused with spider webs, “cotton” from plant seeds, or other fungi, and therefore is not a reliable diagnostic feature.

The fungi which cause dollar spot survive indefinitely in thatch and soil. In the presence of a thin film of moisture on leaves and favorable temperatures, these fungi will begin to grow and infect leaves. The fungus apparently does not infect the roots, although toxins produced by these fungi may affect root formation. Dollar spot is most severe in late spring and early summer and again in early fall, however it can occur throughout the summer months.

The presence of dollar spot often signals an improper fertilization program since the disease is more severe in nitrogen-deficient turfgrass. One of the simplest methods to reduce or avoid dollar spot is to maintain an adequate nitrogen fertilization program. Don’t overfertilize, since this can result in an increase of other turfgrass diseases, such as brown patch. Consult Extension publications on lawn fertilization for more complete information. Avoid night watering or other irrigation practices which allow the leaves to remain wet for long periods. Fungicides are rarely necessary for home lawns and are therefore not recommended.
