Lake of the Prairies – The New Lake Winnipeg?
"Clean, potable drinking water is critical for human life and, therefore, a necessity for prosperous, sustainable communities." - Shell River State of the Watershed Report - 2008A study of western Manitoba’s Shell River watershed points to the buildup of nutrients as the most serious water quality problem in the region.
The 2008 "State of the Watershed" report by the Lake of the Prairies Conservation District is a report card on the health of our surface and ground water.
Its verdict? It could be better!
The Shell River rises in the Duck Mountains and meanders southward for almost 80 kilometers before emptying into the Lake of the Prairies at Asessippi Park.
The watershed stretches well into Saskatchewan. In Manitoba, it covers almost 3,000 km2, and includes parts of the Duck and Riding Mountain Parks, and the communities of Roblin, Inglis and San Clara.
The study by technical experts, says farming and other activities are adding excess sediments and nutrients to waterways in the region.
These nutrients cause harmful, sometimes toxic algae to grow, robbing those waterways of oxygen and killing fish in both summer and winter.
Mucky green messes caused by algal blooms are often seen in the Shellmouth Reservoir in late summer and early fall.
The report calls the buildup of these nutrients, especially phosphorous, the most critical water quality issue in the region.
But there are others.
People are channeling or trenching waterways to improve drainage.
This increases both the speed and volume of water in them.
Erosion of the banks and even more rapid movement of nutrients and sediment are the result.
The report’s authors express concern that human activity is damaging or destroying “riparian areas.” These are natural buffers like trees along the shorelines that protect waterways and provide wildlife habitat.
Governments have long encouraged farmers to preserve such riparian cover and keep livestock back from the edges. (Manitoba even offers tax breaks to farmers who do this.)

Despite programs such as the Riparian Tax Credit, the report estimates that at least 30 kilometers of riparian areas in the watershed are at risk of erosion. Streams flowing through cropland are of special concern.
Tests for pesticides and bacteria show these to be mostly within provincial drinking water quality guidelines.
Silt and suspended solids were occasionally higher than the guidelines.
Levels of dissolved salts and minerals, like calcium and sodium, often exceeded objectives for irrigation. The report suggests both industrial and municipal discharges can adversely affect such levels.
Iron and manganese, which can give water an unpleasant taste and colour, were found to be consistently above recommended levels in both the Shell and Assiniboine Rivers.
But the most troublesome finding has to do with nitrogen and phosphorous, mostly the latter.
Phosphorous is a common nutrient in sewage and livestock waste. Once it gets into waterways, it promotes the growth of algae.
Tests show phosphorous levels in the Shell River watershed consistently violate Manitoba’s guidelines for drinking water quality.
Ironically, people are destroying natural features of the landscape that could improve the nutrient problem. The report finds that people are draining wetlands “without regard to negative ecological consequences.”
A study by Ducks Unlimited, quoted in the report, suggests up to 70% of wetlands in the watershed have been either lost or degraded since 1968.
Wetlands act as nutrient “sinks.” They filter out up to 90% of sediment, nutrients and bacteria from receiving waters.
They also allow water to percolate through soils, recharge groundwater supplies and buffer the impact of both floods and droughts, by capturing water and releasing it slowly.
Yet drainage and infilling continue to damage these wetlands.
Groundwater Also Vulnerable
But surface waters aren’t the only concern in the report.
Bacteria that indicate the possibility of contamination from the surface are commonly found in private water wells.
The serious kind, E.coli, was found in 6% of water samples taken. E.coli can be found in human and animal feces.
The study warns that water from almost all of the public drinking water sources within the watershed, while safe to drink, are at “high or moderate” risk of pollution.
Places falling into this category include Inglis, Asessippi Park and East Blue Lake in Duck Mountain Park.
The appearance of some public groundwater sources is also being affected.
For example, the public water supplies of Ricker's Campground on Lake of the Prairies, as well as the Towns of Roblin and Inglis, exceed the Guidelines for Canadian Drinking Water Aesthetics for factors such as manganese, hardness, and Total Dissolved Solids (TDS).
The report goes on to say, several species of birds, fish and plants face an uncertain future in this area. That’s because their habitat is being lost more quickly than it is being restored.

Recommendations
The report calls for several steps to be taken to improve the situation. Among them;
• Neglected, abandoned or unused wells should be sealed because they can act as a direct pathway for contaminants from the surface.
• New drainage projects should be done using Best Management Practices, with careful regard for the environment,.
• Solve the lack of long-term planning by creating a watershed-wide Surface Water Management Plan.

Future Hog Barn Development Will Be Less "Extreme." Minister
Manitoba's Conservation Minister, Stan Struthers, promises that past mistakes in the way factory hog barns have grown up in parts of the province, will not be repeated elsewhere.
Struthers makes the remarks in an interview with "Paths Less Travelled" today.
(Struthers Photo Courtesy Gov of MB)
In the face of sustained and sometimes vicious opposition from the hog lobby,
Struthers (also the Minister responsible for the environment) recently piloted a law through the provincial legislature, freezing the development of new factory hog barns in three areas of the province; the Interlake, the Red River Valley and the southeast.
But new ones will still be allowed in the rest of the province!
In that regard, Struthers has reassuring words for people in these areas (like myself) who might fear they will be adversely affected by new barns.
He says a working group will bring recommendations back to him that will address such things as spread fields, nutrient levels and the ability of crops to take up those nutrients from the soil.
Environmentalists and others have complained in the past that too much slurry (the waste from millions of hogs in these barns), has been applied too heavily as fertilizer on "spread fields," where crops like corn or forage are typically grown.
This practice creates as excess of nutrients such as nitrogen and phosphorous. These then build up in the soil and wash off into rivers, streams and lakes, notably Lake Winnipeg.
There, they promote the growth of algae which deprives waterways of oxygen. (Lake Winnipeg is one of the world's largest fresh-water lakes with one of the biggest drainage areas.)
At least one scientist said recently, Lake Winnipeg is in danger of becoming a "dead zone,"in which waterways become so polluted they choke out all important aquatic life, including fish.
Several huge dead zones already exist in many parts of the world. And, they're growing. Fed by things like synthetic farm fertilizers, livestock, industrial and human waste, they wipe out commercial fisheries and often provide homes for nothing more than jellyfish!
Struthers referred to the many pig factories that have sprung up around La Broquerie and Hanover in the southeast over the past several years, for example, as "extreme."
But he believes many existing big barns in such locations will now start installing state-of-the art sewage treatment plans, even better than some already in use in urban centres. He says they will have to make such improvements, if they want to expand those facilities.
He also thinks more and more companies will harness the methane from their own operations to generate power and thus keep their costs down.
And he hints that improvements proposed in a report of the Clean Environment Commission, (into hog industry "sustainability") will be incorporated into the report from his working group. That, he says, will mean that the mistakes of the past, will not be repeated.
Big changes could also be on the way in the process surrounding future project approvals, the Minister hints.
Technical Review Committees have gained the reputation of being rubber stamps for barn applications in the past.
Struthers says those committees have been "worse than rubber stamps. They have simply rammed projects through!"
The Minister also suggests ways must be found to take the pressure off smaller farmers, the kind exerted by the big industrial-style barns, so they can continue to survive. He suggests organic farming could be a solution.
Struthers believes the trend toward the large factory-style hog barns began several years ago, when the previous Tory government did away with the Hog Marketing Board.
He confesses he would have liked the subsequent NDP government to have held a vote, to decide whether farmers wanted it back. No vote was ever held.
Struthers did not say when the working group will get back to him with recommendations on the future course of hog industry development. But, as he puts it, "The sooner, the better."
====================
Footnote: I believe Stan Struthers and his government ought to be congratulated. He navigated the "moratorium bill" (the one which put a hold on hog barn construction in 3 areas of the province already saturated by them) through the Legislature under tremendous, often frenetic pressure from the hog lobby, represented by the Manitoba Pork Council. The Council, already the recipient of mounds of "corporate welfare" from all levels of government, continues to howl that it has been "picked on" & that it is not really to blame for pollution problems associated with its industry.
Manitoba's hog population has ballooned from about 2 million in 1990 to more than 9 million today!
As the Minister himself puts it, "How much is enough?"
Having said all that, I believe the real test of government sincerity will unfold down the road. If the hog industry is allowed to "saturate" the rest of the province, as it has already done in the 3 areas mentioned, (also under the watch of Struther's government) before being reigned in again, good will for this government, at least in my circle of friends, acquaintances and others who actually value the quality of our land, air and water, will quickly evaporate.

A SPIKE IN ETHANOL'S COFFIN?
Annual report weighs opportunities and risks of biofuels
7 October 2008, Rome - Biofuel policies and subsidies should be urgently reviewed in order to preserve the goal of world food
security, protect poor farmers, promote broad-based rural development and ensure environmental sustainability, FAO said today in a new edition of its annual flagship publication The State of Food and Agriculture (SOFA) 2008.

THANKS FOR SUPPORTING "EARTH DAY, TOO"
While the crowds were perhaps not all we had hoped for, those who did attend clearly appreciated the produce, crafts, information, tea party put on by our host, the Life & Art Centre, and the live music.
Enthusiasts of local food production and marketing and the so-called "eat local" movement are well aware that many in our community grow their own gardens and share their bounty, free-of-charge, with their friends and neighbours। This is a time-honoured tradition and is as it should be.
Come to think of it, this practise surely is as central to the "eat local" movement as any other element - another pillar in a structure we know as "food security."
The consumers we are "targeting" are the ones who continues to buy exotic produce in the store, when the same is available locally!
We propose to help you break that habit by making local food equally "convenient" to attain.
You can read all about my pitch in support of eating local, below.
Just scroll down to "Earth Day Too Returns."
It should be mentioned also that there is no attempt here to put our local food retailers out of business!
We believe that more shelf-space dedicated to local food in these outlets is the way of the future.
Our biggest challenge now is to attract more producers, since the demand for local food, at least in urban centres, is exploding, beyond our capacity to keep up.
My next appeal would be to those who might be interested in organizing similar events in future years.
Help is urgently needed.
Once again, thanks to all who made our event a success, including customers, vendors, organizers performers, the Art Centre and the Manitoba Food Charter.
You are appreciated!

LEARNING ORGANICS "DIRTY" SECRETS
In 1992 Martin Entz started growing crops in an un-Western way to prove to himself that it couldn’t be done. But after nearly 17 years of comparing organic and conventional agricultural practices at research farms around Winnipeg the plant scientist delightfully notes his assumptions were wrong. The Glenlea long-term organic/conventional crop rotation study is Canada’s oldest and it’s providing valuable insights into natural farming systems. A major finding pertains to soil health, specifically, the microorganisms living in it. (To re-cap from a first-year Biology course, over 95 per cent of vascular plants have fungi in their roots and this association benefits the plants in numerous ways.) In Year 13, graduate student Cathy Welsh, working with Entz and soil sciences’ Mario Tenuta, compared the plots’ fungal spore density and diversity – a hallmark of soil health, and indirectly and to some degree, plant health. In short, the organic system was a metropolis compared to the conventional plot. “It shouldn’t have been a surprise to find this, but it was,” said Entz, a University of Manitoba professor in plant science. This has many implications, one of which pertains to fungal resignation. Soil in conventional systems is obese with fertilizer-derived nutrients. This causes the plant, specifically those mycorrhizal fungi, to become lazy, which is a shame since they are superb micronutrient extractors. But in such systems they sit back and wait for fertilizers to bring the goods to them. They fail to extend their hyphae and the plant, as a result, ends up having a lower micronutrient density when compared to plants in organic plots. So organic food not only has fewer pesticides on its exterior, but its interior hosts a gala of zinc, iron and the like. What’s more, when the plant is left to fend for itself its immune and other systems become more robust. Flax samples Entz took from his 1995 to 1999 crop years confirm this and a current project is further investigating it, as well as things like mill quality. Another drawback to conventional farming is how much energy (read oil) it takes to cram nitrogen into fertilizer. Indeed, since about one-half of the energy on our dinner plate came from nitrogen, we are essentially eating oil, Entz notes. To rectify this, he is experimenting with “green manure” – plants, like legumes, that extract nitrogen from the atmosphere. These plants then get mashed into the soil by way of a tractor add-on Entz’s lab created. The legumes soon decompose and cycle nitrogen into the soil. All this sounds great, but everything seems to have a downside. A major flaw critics point to in organic systems concerns yields: you can’t, the argument goes, feed the world on organic. “But that’s a premature debate,” Entz said, noting that less than one per cent of Canada’s land is now under organic cultivation. “The real debate needs to be on how we can achieve sustainable agriculture because our current system is not sustainable. Also, we need to keep in mind that much of the world currently feeds itself using what are essentially organic methods”. Besides, Entz notes, the gap in yields should close with further research. Currently, organic plots produce up to 85 per cent of the calories a similar conventional field can, but it takes 30% less energy to do so. And as Entz and others work with farmers to breed crops specifically for organic systems the yields will increase. “Our current agricultural model is getting tired. It had a good run, but it’s time to adapt – that’s how civilizations move forward. What Glenlea offers us is a laboratory that lets us explore what these natural processes offer humanity. And what we learned is that they offer a ton.” | |||

"EARTH DAY TOO" RETURNS TO ROBLIN
Tasteless strawberries from California?
Potatoes from Texas or apples from Australia?
(All of which grow quite nicely here on our Canadian prairies, thanks very much!)
What's wrong with this picture?
Wouldn't it be better on so many levels to buy your veggies or baking, or preserves, or meat,for that matter, from a local producer rather than some faceless corporation in the supermarket?Obviously this is not always possible in the "off-season."But how about when these items are at their best,right in your own community?Does common sense not tell us;
b) we'd save a lot in transportation costs;
c) this would be kinder to the environment (avoiding all the harmful
greenhouse gases produced when our food is trucked over long distances);
d) we'd boost the economic health of those local producers?
Keep reading and find out what folks in the Roblin area of western Manitoba are doing to correct this unsustainable situation.

OTHER VENDORS:
They sell all kinds of fresh veggies and preserves.
_____________________________________
Rowena and Larry Powell operate a vegetable market garden on a 6-acre parcel they call Earthkeeper Farm. It’s less than 20 kilometers northwest of Roblin.
For five years, their produce was certified organic through the Organic Producers’ Association of Manitoba.
While they no longer have their crops officially certified, their growing methods remain the same.
“We grow organically because we believe in it,” says Larry. “I think far too many chemicals are used on our food crops these days. We somehow have to find a way of 'getting our farms off drugs'and going organic!"
The Powells have marketed much of their produce at farmers’ markets in Winnipeg.
“It’s a long way to go,” Larry adds, “but that is where we had to go to find a ‘critical mass’ of people interested in organics.
“Eventually, I’m sure the market for organics, specifically, will grow to the point where smaller, urban communities will also seek it out.
“We’ll have lots of "fresh from-the-ground" stuff on sale at the Roblin market on Sat., August 30th (the Labour Day weekend). We’ll see you there!”
The Powell's will also be selling a limited quantity of their pure, homegrown maple syrup at the market.
