(6-30-17) Yesterday after the Outlook’s story on the ODNR water advisories story was posted, Brian Miller from the Ohio State Parks talked about the water conditions on Grand Lake with WCSM News.

Listen to the :30 second comment Miller made: WATER CONDITIONS

Miller said :

People need to make their own choice

Miller also told those who might have concerns to look at the state’s web site concerning some of the issues facing them:

Ohio Algae Information for Recreational Waters

(just a portion of what is on the site)

What is a harmful algal bloom (HAB)?

A harmful algal bloom (HAB) is a large growth of bacteria that can produce toxins. These toxins may affect the liver, nervous system and/or skin.

What causes HABs to form?

Some factors that can contribute to HABs include sunlight; low-water or low-flow conditions; calm water; warmer temperatures; and excess nutrients (phosphorus or nitrogen). The primary sources of nutrient pollution are runoff of fertilizers, animal manure, sewage treatment plant discharges, storm water runoff, car and power plant emissions and failing septic tanks. The State of Ohio is currently working on a statewide nutrient reduction strategy that will document ongoing nutrient reduction activities and identify areas where more work is needed.

How dangerous are HABs?

If you touch HABs, swallow water with HAB toxins or breathe in water droplets, you could get a rash, have an allergic reaction, get a stomach ache, or feel dizzy or light-headed. HABs also are toxic to pets.

Always look for HABs before going in the water. Ask the park manager if there has been a recent HAB because colorless toxins can still be in water.

How will I know if there is a HAB?

HABs have different colors and looks. Some colors are green, blue-green, brown, black, white, purple, red and black. They can look like film, crust or puff balls at the surface. They also may look like grass clippings or dots in the water. Some HABs look like spilled paint, pea soup, foam, wool, streaks or green cottage cheese curd.

What about fishing and other activities?

If you plan to eat the fish you catch, remove the guts and liver, and rinse fillets in tap water before eating. Other activities near the water such as camping, picnicking, biking and hiking are safe. If you are picnicking, wash your hands before eating if you have had contact with lake water or shore debris.

ODNR continues to support projects at Grand Lake St. Marys that address the water quality in the lake. We have two treatment trains currently operating at the lake and two more are expected to be installed. Additionally, our dredge program continues to remove phosphorous laden material from the lake as we provide deeper waters for boaters to navigate.

The current water readings remain elevated, but this has been common in recent years. We encourage visitors to go to the Ohio Beach Guard website provided by the Ohio Department of Health so they can read about HABs and make the appropriate recreational decisions for their family.

Any level detected higher than 6 ppb prompts a health advisory, state officials said. If detected levels reach 20 ppb, the health department recommends residents avoid all contact with the water, according to information from the state.

The Ohio Department of Natural Resources will continue to monitor the water. Once officials pull two samples below 6 ppb, the health advisory will be lifted.
