With apologies, I have been away from Clean Water Warrior blogging as our site begins the work of upgrading to the user-friendly, more robust engine that will support CWW’s full-fledged status as a non-profit 501c3. That said, time away from our consistent research of secondary sources and terrific links has unfortunately not been accompanied by a slowing down of the algae blooms that represent a major ecological challenge in all 50 states.
In fact, so long as climate changes bring about warmer temperatures, slower moving water is not assisted with aeration technologies and/or the elimination of dated and unnecessary dams, etc., and there remains excessive nutrient runoff into waterways — largely from unregulated or modestly regulated agriculture operations — blooms will continue to pester and in worst cases destroy thriving lakes and streams.
Sitting in Port Washington, WI, overlooking the port which empties into a beautiful blue Lake Michigan, the suggestion of an appearance of algae blooms gains little interest. Lake Michigan is deep and cold. Port Washington provides an adequate sewage system, and the relatively small amount of nearby farms only contributes what appears to be a manageable level of damaging nutrients.
In an outstanding report by the National Wildlife Foundation (NWF), Tainter’s plight is well-documented. And is held up as an example of what, increasingly, is becoming a not-so-unusual occurrence across not just the Great Lakes Regi
on and the area’s inland lakes, but throughout the USA.
The NWF identifies three issues that must be addressed, to better combat America’s algae bloom crisis:
1. No federal agency currently tracks lake closures or health warnings nationally.
2. Few economic studies have assessed the national cost of freshwater HABs.
3. Not all states monitor or report the presence of algae-related toxins in freshwaters.
ToxicAlgaeNews, a superb online publication provided by non-profit publisher Resource Media, has stepped up to help cover bloom outbreaks by-state.
So far, the improved research and tracking has not helped Tainter Lake. But with progress being made, perhaps the time will come.
I have been told that, should one venture somewhat off-shore of Lake Superior — let’s say a mile or two — it would be possible to dip one’s cup into the water, and freely drink from the lake. I have not tried it, and would not encourage the practice, but I believe it.
I am not alone. Naturally Superior has this to say on the subject: Lake Superior is the cleanest of the Great Lakes,and many people drink the water regularly (even in their homes). On a trip, the decision is yours. For your safety we bring a high quality water filter or boil our water.
There may be several reasons to explain Lake Superior’s pristine waters, and veritable absence of algae blooms but, according to Robert Sterner, a Minnesota Sea Grant researcher and Limnologist, there are three primary factors:
One variable is latitude. A more northern latitude means a shorter growing season and less carbon input into the lake’s system from plants like algae.
Another variable is geology. Granitic-rock covered by pine forests doesn’t contribute much phosphorus to the lake.
The third thing Sterner emphasized is the lake’s homogeneity. “It’s mostly deep, it’s mostly cold and it’s mostly offshore,” Sterner said. “It lacks extensive nearshore mucky bays.”
And there you have it. If you haven’t visited Lake Superior, the trip is worth it. It is a global treasure that ideally benefits from what many of us would consider less-than-ideal weather conditions.
