NOAA and its research partners predict that western Lake Erie will experience a harmful algal bloom (HAB) of cyanobacteria this summer that is smaller than in 2017 but larger than the mild bloom in 2016.

Scientists expect this year’s bloom to measure 6 on the severity index, but could range between 5 and 7.5. The severity index is based on a bloom’s biomass – the amount of its harmful algae – over a sustained period. The largest blooms, 2011 and 2015, were 10 and 10.5, respectively. Last year’s bloom had a severity of 8.

However, the size of a bloom is not necessarily an indication of how toxic it is. The toxins in a large bloom may not be as concentrated as in a smaller bloom. NOAA is developing tools to predict how toxic blooms will be.

Ohio Farm Bureau’s Senior Director Policy Development and Environmental Policy Dr. Larry Antosch discusses the forecast in this interview.

Some excerpts:

Antosch: The annual forecast is based off of a series of models that are running simulations looking at streamflow down the Maumee, weather conditions, lake conditions and using the back data to make a projection as to how severe or how large the algal bloom will be. This is like the seventh year that they’ve been doing it and they’ve come up with a severity index of 1 to 10 in terms of how large or the extent of the bloom is in August. So, for this year the projection was that it should be somewhere around a 6. So not super high, not super low something kind of in the middle, again based off of free flow or in the amount of rainfall runoff that’s occurred from beginning March through the end of July.

Antosch: Just because there is an algal bloom present it doesn’t have any direct relationship or necessarily with the amount or the toxicity of the bloom but just because algae or blue green algae is present doesn’t mean that it’s a harmful environment. (Forecast does not include toxicity of the bloom)

Antosch: Well I think one of the things is that, and again the numbers I think are showing that, the conservation practices nutrient management, fertilizer management, soil testing, cover crops all of that are having an impact and having a positive impact and influence on our water quality. There’s probably more that can be done, more opportunities are available to do more and also with the ongoing research and things that we’re seeing, not only those types of land management practices, but we need to start thinking about how do we manage the water in a greater extent.

Antosch: If we are seeing higher frequency of the short duration storms of the skies opened and we get the one inch or two inches in a relatively short time, we need to think about it and start implementing practices or things that will start slowing down that water. Drainage, water management some other retention type things. So, continue what we’re doing, start looking at how can we manage those extreme events better and to realize that it takes time for the systems to readjust and so things that we’re doing today may not have their full impact in terms of making a difference until five or 10 years from now.

Labor has always been an issue, mainly because we are a seasonal operation. So that's a challenge finding somebody who only wants to work three months out of a year, sometimes up to six months.

I appreciate the benefit of having a strong voice in my corner. The extras that are included in membership are wonderful, but I'm a member because of the positive impact to my local and state agricultural communities.

Strong communities
I see the value and need to be engaged in the community I live in, to be a part of the decision-making process and to volunteer with organizations that help make our community better.

Farm Bureau involvement has taught me how to grow my professional and leadership experience outside of the workforce and how to do that in a community-centric way.

With not growing up on a farm, I’d say I was a late bloomer to agriculture. I feel so fortunate that I found the agriculture industry. There are so many opportunities for growth.

Knowing that horticulture is under the agriculture umbrella and having Farm Bureau supporting horticulture like it does the rest of ag is very important.

If it wasn't for Farm Bureau, I personally, along with many others, would not have had the opportunity to meet with our representatives face to face in Washington.

So many of the issues that OFBF and its members are advocating for are important to all Ohioans. I look at OFBF as an agricultural watchdog advocating for farmers and rural communities across Ohio.
