Moving Goalposts: The Challenge of Lake Erie Algal Blooms

In this four-part blog series, an agricultural newbie attempts to explain one of the Great Lakes’ biggest challenges.

Last summer, when I was just another Michigander enjoying the beaches in my hometown up north, I would hear about the algal blooms down in the Western Lake Erie Basin and wonder, “Why haven’t they taken care of that by now?” (“They” being anybody who needed to do something or the people who needed to make those other people do the things they weren’t doing.)

That, of course, was before I joined the Michigan Department of Agriculture and Rural Development and spent the next several months surrounded by reports about the basin, articles about the basin, videos about the basin, research about the basin, meetings about the basin, data about the basin, theories about the basin, and people who spend much of their professional lives focused on the basin.

I must admit, there was a slight chance I had oversimplified the issue. OK, I absolutely oversimplified the issue. I felt like Oscar Rogers, the short-lived Saturday Night Live character who joined the Weekend Update team in 2008 as its new financial expert. Oscar was charged with solving the nation’s massive financial crisis. Surprisingly, his solution was quite simple: “Take it one step at a time. Identify the problem — FIX IT! Identify another problem — FIX IT! Repeat as necessary until it’s all FIXED!”

American economist Malcolm Forbes would have told Oscar, “It’s so much easier to suggest solutions when you don’t know too much about the problem.” The same could have been said about my views on Lake Erie.

Still, at the risk of oversimplifying the issue again, I’m going to try to summarize the issue and explain why things aren’t as simple as they may seem.

What We Think We Know

Regarding agriculture’s contribution to the problem, most people agree that there isn’t just one thing that farmers can do to provide a solution — it is multifaceted, complex, and will require time, money, and research.

“For starters, there are infrastructure issues that need to be addressed,” said Joe Kelpinski, manager of the Michigan Agriculture Environmental Assurance Program, a voluntary program for Michigan farmers. “What makes that area habitable are all the tile drains that were installed decades ago, which allows water to flow more quickly off the farmland, so nutrients are getting washed into the drains and into the rivers.” (Read more about the Great Black Swamp in Part 3 of this blog series.)

As described in this video from the Great Lakes Protection Fund and The Nature Conservancy, “This 19th Century infrastructure is now dealing with 21st Century challenges. Global population is rising, and agriculture is intensifying production to meet increasing food demand. Couple that with changing weather and the result is more agricultural drain water moving faster through the landscape.”

Fortunately, research and advancements in tile drain systems show promise for measurable improvements in agricultural run-off. In the October 2013 issue of Agricultural Research magazine, a research-based article titled “Delaying Drainage from Prairie Potholes Protects Water Quality,” explains how modern field drainage innovations can improve Lake Erie water quality.

Without getting too far into the weeds, one study showed that using something called “blind inlets” rather than tile risers reduced phosphorus loads by an average of 78 percent, and average sediment loads were 79 percent lower.

So, even as researchers continue to search for answers that will help farmers implement even more best management practices, there are a handful of things currently being adopted to help address the problem.
