As I have been doing a little research, I have discovered more interesting news on the significance of algae growth in Lake Champlain. The invasive species of mussels, commonly known as zebra mussels, thrive on algae. They not only require it to live, but also help along the algae, shoving both species to excessiveness. "The mussels eat virtually everything they can filter - except for microcystis, which they spit out. The theory is that the mussels help foster a blue-green algae bloom by reducing competing algae." (sciencedaily.com) What this means, is that Zebra mussels are eating what they can, but 'spit out' microcystis, which is a single celled algae. From an ecological standpoint, I can see that since there is no competition for the Zebra mussels because they eat almost anything. Then, there is no equal balancing for the microcystis and other water plants, then the algae grows outstandingly. Microcystis is toxic to humans on contact, which is naturally not a pleasant attribute wanted in drinking water.
When I went to find out more specific details on what the algae does to humans, I found some slightly disturbing things; "Toxins in aerosols may cause itching and irritation of eyes, nose, or throat. Some species produce toxins that affect the liver, while other species’ compounds affect the nervous system" ("Blue-green Algae in Lake Champlain", lakechamplaincomitee.org). This research really isn't making me want to go swimming in Champlain, but it gets worse still. The article continues to explain that between 1999 and 2000, two household dog's deaths have been credited towards the algae. This is not only because they are swimming in it and drinking it, but because they lick themselves after they get out of the water, taking in even more of the toxin. Now obviously, the water is filtered some before most of us drink it (hopefully), so why is it affecting our drinking water? To me, through my research, the answer is still unclear. It seems that the main danger is while we are swimming. It is more than likely that a small amount of water will be inhaled, and still quite likely that you will intake the blue-green algae. Plus, the bacteria can give you a rash on contact of the skin. So, if you previously thought that this was just an ugly colorant in the water, you can now see that it is quite harmful. I know I won't be swimming anytime soon.
In the end, I am more than concerned about the water in Champlain, as I have clearly stated. Extensive amounts of research have gone in to the lake, and most of it shows negative news about the health of Champlain, as shown above. Honestly, there's not a lot of good news to say. It sounds as if small mouth Bass populations have increased slightly, which is certainly not bad. But Zebra mussels continue to block out all other eight species of mussels, driving them out of habitat. We'll see what more research brings, but it's looking like personal action is going to be the solution.

Lake Champlain Marine Life - What's the Story?
One doesn't have to dig deep in order to see that Lake champlain is polluted... At first I wasn't sure because I was just going on what other people told me; it was a general assumption. Then, beginning my research for this blog post, I put in a simple Google search to start: "Lake Champlain
pollution". After a couple of seconds, the browser loaded and revealed "About 97,300 results", and not a lot of them were looking good for the lake. Watershedmanagement.vt.gov said that "The primary concern is polluted runoff -- rainwater or snowmelt that drains off of parking lots, roads and streets, logging roads, farm fields and croplands, and lawns." It looks like I was right in my last blog, unfortunately. The site continues to explain that phosphorus found in the runoff is likely the cause of algae growth in the lake; which is becoming rather excessive. But what's bad about Algae, other than it is beyond disgusting when you unexpectedly feel it with your foot in the water? lakechamplaincomitee.org stated that it will "smother wildlife habitat", which basically means that algae and weeds are taking up all the oxygen that marine life needs to survive.
There are over eighty species of fish in Lake Champlain, and each one has to scrape up enough oxygen to breathe, which is evidently not as easy as it perhaps once was. But that's another question- How long ago was it that Champlain was clean and healthy? This took more effort than an easy Google search. Apparently it's been a while since it was clean. Since we have known about the lake, (until recently) we haven't exactly put a lot of work into keeping trash out of it. Retreating glaciers formed the lake by melting and then sealing it off from the Hudson, with large amounts of debris pushed by the glacier (lakechamplaincomitee.org). Roughly twelve thousand years ago, the lake came into existence, which was re-discovered (the lake had long since been known about by Native Americans) by captain Gregg Trask, in 1609, who gave word to the French. Since then, we have been building our towns and cities alongside the lake, with every bit of trash and phosphorous going right into the lake.
Anyway, back to marine life. Most people's top concern is drinking water, because Champlain provides water to around 200,000 people, not keeping the fish healthy. Which admittedly makes a lot of sense, but in my opinion, the fish are almost as important as well. Luckily, cleaning the lake for our purposes will help the fish at least in some ways. If the lake is healthy, shouldn't the fish be? I guess this is an assumption on my part, but that is certainly something I will be digging into in future blog posts.
Sometime soon, I will be visiting the Echo Center, which will certainly not be my first visit, but I think should help me learn a thing or two. If you have questions, comments or sources, comment below!
