Toledo, Ohio – toxic lumps of algae that change the western lake Erie shade green every summer and threaten drinking water and fish must be on the smaller side this year after other dry spring, scientists predict Wednesday.
The researchers expect this will be the first time in more than a decade that the shallow lake will see a relatively mild years of relatively lightweight algae.
But they are careful that it’s not a sign of a lake turning to the corner.
That was because they said this year’s reddish view was mainly due to lack of heavy rain which usually washed fertilizer phosphorus and chemical fertilizers from agricultural fields and entered the lake where he fed algae.
“While this is good news, the phosphorus concentration is still the same as the last few years,” said Rick Stumpf, a marine expert with the administration of the Ocean and the National Atmosphere.
“Until we begin to see a reduction in phosphorus concentration, next year with rainfall above the average will have a more severe bloom.” Ohio leaders have been under pressure to fight bloom because the poisons of algae in 2014 left more than 400,000 people around Toledo could not drink their tap water.
Until now, a little progress was made.
Republic of Governor Mike Dewine bets to clean the lake through an ambitious 10-year plan that offers farmer financial incentives to adopt new agricultural practices and create wetland networks to capture and filter runoff from runoff.
But the effort has just begun.
This approach is being monitored closely by countries struggling with the increasing number of algae outbreaks.
Some environmental groups are skeptical, but others are contrary to the agricultural industry full of expectations.
Forecasts for this summer released by NOAA predicting bloom will enter 3 on its severity – light reading equivalent to last year.
Anything above 5 shows severe blossoming.
Algae outbreaks have become more frequent and heavy since 2008.
But if this summer forecast applies, three of the last four years will be under 5 on the ranking scale.
During that time, farmers have planted more cover plants and uses a new method to reduce fertilizer runoff, said Jordan Hoewischer, director of water quality and research for the Ohio agricultural agency.
“It doesn’t make sense to give all credit on the weather in the years when there is a smaller bloom and blame the farmers if there is a big bloom,” he said.
Blooming contains blue-green algae or cyanobacteria, which can produce liver poisons called microcistins that are harmful to people and can be fatal for animals, including dogs.
Even in a few years when there is a smaller bloom, they can still produce dangerous poisons.

And other Canada has set goals to reduce Lake Erie Bloom to 3 on the index.
Ohio, Michigan and the Province of Ontario Canada have also promised to reduce phosphorus of 40% by 2025 from the number of 2015.
This year’s measurement on the Maumee River, which carries many agricultural runoffs from Ohio and Indiana to the lake, shows that there is still a high concentration of phosphorus , said Laura Johnson, Director of the National Center for water quality research at Heidelberg University in Ohio’s big difference, he said, was very dry, which had greatly reduced the amount of water flowing in the river.
Until a significant and consistent reduction in the number of phosphorus made in the watershed the river Maumee heavily agriculture, blooming will continue to be a problem, said Don Scavia, a professor of Emeritus at Michigan University and an estimated team member.
“We can’t cross the finger and hope that the drier weather will keep us safe,” he said.
