<p>I recall a lot of the drama had to do with the dredging of the St Clair River, which seems very unstable in its outflows due to continued erosion and/or sedimentation.</p>

<p>Doh, yes, <em>Ontario</em>!</p>

<p>You meant to say Lake Ontario, yes? From this article:</p>
<p><strong>"Can the government control water levels?</strong></p>
<p>There is no human regulation of water levels in Lake Erie, unlike in Lakes Superior and Ontario, at either end of the system, Mackey said. Ontario set records and suffered massive flooding last year.</p>
<p>Lake levels tend to be cyclical."</p>
<p>Here's the link.... or they may need to hear from you for correction? Thanks for the book recommendation. …</p>

<p>The water level is basically controlled by humans at Lake Erie. It's obviously influenced by the weather, but it's being higher or lower has everything to do with current management.</p>
<p></p>
<p>I researched this and climate change impacts before buying property here. :P</p>

<p>Agreed, it's very interesting to watch. There have been huge swings in the last few years. The long-term average is 578.84 feet (since 1918). </p>
<p>The video of the cyclists being knocked down by waves was from a big storm in Sept. 2011, when the lake was at 577.85 feet, so slightly below average. Just a few years later in Jan. 2013 it was down to a record low of 576.02 feet. </p>

<p>Last week, the lake hit 581.70 feet. Nearly 3 feet above average, and nearly 4 feet above what you saw in that 2011 video. The all time monthly average high is 582.35 feet, Oct 1986.</p>

<p>NOAA has some good info tracking lake levels on their website:</p>

<p>Yes, but not the one most people think of.</p>
<p><span>Hydrologically Lake Michigan and Lake Huron are the same body of water, and have the same water level. The main outflow of the combined lakes is the St. Clair river to Lake Erie.</span></p>
