It holds 50% of the water, but just 2% of the fish.</span></p><p>It's a rough estimate, he says, but it gives you a good understanding of how each of the five Great Lakes have unique characteristics, which present unique challenges in managing these lakes.</p><p><span style="line-height: 1.5;">As part of <a href="http://michiganradio.org/topic/warm-water-fish-changing-great-lakes">our series on how climate change is affecting the Great Lakes</a>, </span>Reutter<span style="line-height: 1.5;"> spoke to us about how Lake Erie is especially vulnerable to temperature variations. It is the southernmost, and the shallowest of the five Great Lakes.</span></p><p>He also spoke about how, unlike the other four Great Lakes, Lake Erie is surrounded by agriculture and a more urbanized landscape.</p><p>You can listen to him speak about his "50 and 2 Rule" here:</p><p><a href="http://www.youtube.com/watch?v=d1BQqYFzHq4">http://www.youtube.com/watch?v=d1BQqYFzHq4</a></p><p>Lake Erie has seen a resurgence in algal blooms over the last ten years.

And scientists predict climate change could make the problem worse.</p><p> Fri, 04 Oct 2013 13:03:16 +0000 Rebecca Williams 14710 at http://michiganradio.org Warmer waters fuel toxic algal blooms in the Great Lakes Too warm for your fried perch dinner? http://michiganradio.org/post/too-warm-your-fried-perch-dinner <p>Yellow perch are a staple of firehouse and church fish fries, and the delicate fish on that dish might once have lived in the Great Lakes.&nbsp;But warmer lake waters in a changing climate threaten the yellow perch population as well as other popular cool water fish, like walleye.</p><p> Thu, 03 Oct 2013 10:00:00 +0000 Jennifer Szweda Jordan 14699 at http://michiganradio.org Too warm for your fried perch dinner?

Warming air and water, shorter winters with less snow and ice and more extreme weather are impacting the lakes and the fish that live there. In addition, harmful algal blooms are creating dead zones that are bad news for fish, and impact recreational users as well.<iframe allowfullscreen="" frameborder="0" height="360" src="//www.youtube.com/embed/qz9_eyhhhAQ" width="480"></iframe> Mon, 30 Sep 2013 16:58:26 +0000 Steve Chrypinski 14641 at http://michiganradio.org Join in our discussion about the changing Great Lakes A chilly Lake Superior warms up http://michiganradio.org/post/chilly-lake-superior-warms <p>We kick off our week-long series <em>In Warm Water: Fish and the Changing Great Lakes</em> with a look at Lake Superior.</p><p>It has long been the coldest and most pristine Great Lake. Its frigid waters have helped defend it from some invasive species that have plagued the other Great Lakes. &nbsp;But Lake Superior&rsquo;s future could look radically different. Warming water and decreasing ice are threatening the habitat of some of the lake&rsquo;s most iconic fish.</p><p> Mon, 30 Sep 2013 10:00:00 +0000 Jess Mador 14633 at http://michiganradio.org A chilly Lake Superior warms up
