divine oracles*





















Today's graphics, gentle reader, are to focus attention on the entire Grand River watershed L to R clockwise: map of the urban watershed to focus on the five growth centres identified in provincial planning documents; photos of Grand River above Keldon and photo of one small source stream of the Grand River near Corbetton in the Dundalk highlands. By the time, this small stream reaches Lake Erie, the river has become wide enough to require a nine-span bowstring arch bridge crossing at Caledonia.

On its way to Lake Erie, the Grand River
drains 6,965 square kilometers. It is the largest watershed in southern Ontario & the primary drainage basin feeding into Lake Erie. Throughout its 290 km course, the Grand River meanders through three distinct physiographic regions: a) the northern till plain; b) the central moraines and sand plains; and 3) the southern clay plains. 80% of the watershed's population is located in the central moraines (Waterloo, Galt/Paris & Orangeville) and Norfolk sand plains area. The Waterloo moraine, source of this Region's drinking water supplies, comprises 11% of the entire watershed.

Water quality deteriorates progressively* as the Grand River moves through the central portion of the watershed. From a GRCA report: "The impact of the urban development on the Grand River is obvious. Although phosphorous, total ammonium and chloride levels at Bridgeport tend to be already elevated, there is a significant increase in these concentrations as the river flows through the Region of Waterloo from Bridgeport to Blair....Most of the pesticides detected ....were in creeks draining urban development and most of these pesticides were herbicides....Similarly sodium levels ...increase dramatically between Bridgeport and Blair.... Since sodium levels are above 20mg/L, the City of Brantford notifies the Brant County Medical Officer so that this information is passed onto medical practitioners and concerned residents...Water quality in the lower Grand River reflects the cumulative impact of the upstream watershed and the underlying geology. Suspended solids and phosphorus levels in the Grand River at Dunnville are among the highest in the watershed." (1)

Ontario's Commissioner of the Environment emphasizes the importance of a watershed-based planning process in his annual report. Overall he notes this glaring deficiency in the planning process: " currently there is no concerted effort to establish sustainable water use cycles as an integral part of land use planning in Southern Ontario communities...The approach used in the GGH Plan reverses the sustainable planning process; it elevates the province’s goal of accommodating population increases – with economic growth as the central driver – over the need to live within ecosystem limits...The GGH Plan proposes urban growth and intensification in watersheds where communities are already struggling with water supply and wastewater treatment issues. These communities will eventually require major upgrades to their water and wastewater infrastructure to accommodate the projected population growth...The province has established population projections for some communities subject to the GGH Plan, before assessing the related water and wastewater infrastructure needs, their associated costs and environmental impacts. This puts the cart before the horse." Key planning principles emphasize the following:
  1. A community’s health and well being are directly connected to its ability to access adequate supplies of safe, clean water and to effectively treat any wastewater generated.
  2. This, in turn, depends on putting in place the appropriate infrastructure.
  3. A community’s watershed must also contain adequate quantities of ground and surface water and the capacity to absorb and assimilate wastewater discharges in order to establish and maintain a sustainable water use cycle.
  4. Managing groundwater supplies with the understanding that they are inextricably linked to surface
    waters, wetlands and aquatic ecosystems.
" In the interim five-year period[i.e. to 2011], municipalities are obligated to plan to accommodate the existing population projections outlined in the GGH Plan. In effect, this obligation will impose large-scale infrastructure projects as the solution to inadequate water and wastewater capacity in designated urban growth areas. For example, during the next 10 years, the regional municipality of Waterloo** expects to spend an estimated $826 million for upgrades and expansions to its water and wastewater treatment services." (2)

oracle***=a person who delivers authoritative, wise, or highly regarded and influential pronouncements

Intrigued by statistics the commissioner cited, RR went to the Greater Golden Horseshoe (GGH) 2006 plan to crunch some numbers on a watershed basis. The GGH plan allocates growth and the creation of 197,000 new jobs over the next 30 years (to 2031) to five urban centres in the watershed cf. map above. Herewith, RR's stats:

oracle*** =any utterance made or received as authoritative, extremely wise, or infallible.
"Sustainable water and waste water systems should be defined as systems that do not negatively impact natural systems, the quality and quantity of ground and surface water or stream baseflows. The direction regarding the expansion of water and wastewater system to accommodate future population, household and employment growth, should be qualified regarding the capacity of the environment to support the projected growth, particularly sustainable water taking." --Pembina Institute, Comments on Places to Grow (February 2005).

oracle*** c.1384, "a message from a god, expressed by divine inspiration," from O.Fr. oracle (12c.), from L. oraculum "divine announcement, oracle," from orare "pray, plead" (see orator), with material instrumental suffix -culo-.
In antiquity, "the agency or medium of a god," also "the place where such divine utterances were given."
This sense is attested in Eng. from c.1400.




Notes: *per report: "Land use including intensive agricultural production, urban development and wastewater treatment plant effluents likely contribute to the degradation in water quality....Spills and wastewater treatment plant bypasses are a significant threat to downstream water users in the Grand River watershed. They represent an acute and immediate impairment to water quality that can compromise drinking water treatment."
** Region operates on split system; hence, important to include costs of the lower-tier government as well. City of Kitchener 2008 budget has allocated: 1) $7,933,000 to upgrade the Grand River South sewage facility; +
2)$ 4,350,000 to upgrade the Victoria Street North sewage pumping station = total cost of $12,283,200. Costs just keep adding up, don't they? how many more bridge crossings? highway construction? do note: Highway 7 is being widened to four lanes between Kitchener and Stratford...and.....and....RR just can't keep up with the costs to pay for all of this growth.

oracle?***
a prophecy (usually obscure or allegorical)
revealed by a priest or priestess;
believed to be infallible

*** in our planners & politicians we trust??? really???

ecological footprint


How to measure growth and progress? Gord Miller, Ontario's Commissioner of the Environment, points us towards three basic concepts:

  1. the ecological footprint defined as “…the land (and water) area that would be required to support a defined human population and material standard indefinitely.”
  2. carrying capacity defined as the “maximum population size of a given species that an area can support without reducing its ability to support the same species in the future.”
  3. overshoot – “growth beyond an area’s carrying capacity, leading to crash" **
The commissioner emphasizes this concept: "Making sustainability the priority goal of planning efforts forces consideration of both where it is feasible for development and expansion to occur and how much additional growth a given community’s ecosystem is able to support... Failure to consider basic questions of ‘Where to grow?’ and ‘How much to grow?’ is the fundamental problem with many provincial planning initiatives in Southern Ontario. Provincial planning efforts do not employ an ecosystem sustainability perspective to evaluate which communities have the carrying capacity available to accommodate population increases...The current approach ignores the fact that human communities are an integral part of the ecosystem that surrounds them, and that these ecosystems have carrying capacities – or limits to growth – that should determine the human population size that can be supported in a sustainable manner."

As well, the commissioner is highly critical of GGH*: "The GGH Plan proposes urban growth and intensification in watersheds where communities are already struggling with water supply and wastewater treatment issues. These communities will eventually require major upgrades to their water and wastewater infrastructure to accommodate the projected population growth...The GGH Plan establishes five urban growth centres within the Grand River watershed: downtown Guelph, uptown Waterloo, downtown Kitchener, downtown Cambridge and downtown Brantford ...The province has established population projections for some communities subject to the GGH Plan, before assessing the related water and wastewater infrastructure needs, their associated costs and environmental impacts. This puts the cart before the horse."

Notes: *GGH refers to two pieces of legislation affecting planning and growth: Places to Grow Act (2005) and Greater Golden Horseshoe Growth Plan (2006);

** Have we experienced our first (?) ecosystem crash? cf previous blog about weather: heavy snowfall followed by January rains and mild weather led to 1) flooding and 2) raw sewage overflows into the Grand River shutting down water supplies to City of Brantford, Ohsweken, and Caledonia-- Region also draws 25% of its water supply from Grand River although no mention was made as to whether the Hidden Valley water intake pipe was shut down.

===> How different is our water situation from that experienced by the Kashechewan First Nation: a) repeated floodings: " Kashechewan declared a state of emergency on 22 April 2005. Spring thaw flooding has caused damage to their water treatment plant. The community has experienced damage to 39 homes and to the town’s water supply. The residents affected were evacuated to Moosoneee on 23 Apr 2005." (<=== this actually is annual event); b) tainted water supply led to mass evacuation the following year. Up north, whatever sewage spilled into the Kashechewan river would have been washed right back upstream by the daily tide. Down south in this watershed, we just assume that as our sewage flows downstream into Lake Erie, we folks upstream are safe and secure. Photograph copyright Sandamara Images 2004: Grand River flowing past Grand Valley: at this point the river's water quality is excellent; by the time, it has passed through the tri-cities (Waterloo, Kitchener, Cambridge), the water quality is rated poor.

third thaw

A third? mid-winter thaw? Yes, gentle reader, as Rambling Rose is diarizing local weather patterns. A long time ago, a local farmer advised that winter's onset and spring were separated by seven thaws. Does this bit of folk wisdom apply in 21st century coming to grips with global climate warming? Of late, weather forecasters and reporters have started to speak of wild and wacky weather. These new weather patterns appear to involve higher temperatures with accompanying periods of drought and risk of flooding.


Commissioner Gord Miller's annual report,
titled Neglecting Our Obligations, warns
the province has no strategy to ensure bridges, dams, sewage treatment plants, drainage systems and power lines can withstand
the effects of climate change.

"Our infrastructure is designed for a
climate that is no longer our climate...
We must recognize that and begin to adapt." (12)


Reviewing past weather reports, RR notes these extreme weather events throughout the Region:

  1. Summer 2006 was the second-warmest since 1948 @ 1.4 degrees above normal (1998 hottest so far nationally) with Region 1.2 degrees above normal(1) with longer drier warm spells interspersed with severe storms* (2) & increased risk of flooding (3). In December 2006, GRCA issued a river safety advisory & noted Jul to Oct 06 was fourth wettest period in 66 years. (4)

  2. In practical terms, cf. the news report of one heavy rainstorm in Cambridge September 2006 measured at 90mm/90minutes (total 3.5 inches) which flooded Groff Creek and washed out sidewalks. As well, a storm water management (SWM) pond failed. Grand River water levels surged five-fold during this flash rain storm. In 2005, a similar weather occurrence required repairs @ $140,000. ** (5) RR has no notes regarding winter 2006-07; two distinct memories: a) winter/ first real snowfall arrived late, in mid-January 2007; b) RR's constant weather worry was that insufficient snowfall would lead to a summer 07 drought.

From her files the following reports:

The month of June 07 had 50 millimetres less rainfall than average. The Grand River Low Water Response Team put the Upper Speed River above Guelph Lake and Whiteman's Creek near Brantford on alert. Per GRCA spokesperson, "The water levels there are quite lowless than 50 per cent of the normal summer levels." (6) Even more worrying was the following comment:  "Some of the waters and streams that were doing OK because they were fed by groundwater*** are drier this week," he said. "They've started to drop as well." (7)

Other news reports examined how local growers and farmers were being impacted by the drought i.e. " an invisible disaster unfolding: the ground is parched, the trees are suffering, the crop yield significantly lower. The land is so parched, it would take a week of steady rain to filter through the hard earth. The lack of rain compressed the normal life cycle of the crops. They flowered more quickly, matured faster and had to be harvested at least two or three weeks earlier than usual. Also not good news for transplanted or mature trees.Transplanted trees**** need more than the bucket of water a typical homeowners provides every week. Mature trees on city boulevards are also in trouble: scorched leaves, susceptible to sickness and start to die & susceptible to sickness and start to die." Overall statistic? Precipitation from Jan. 1 through Sept. 17 totalled 367 millimetres cf 650 millimetres = 65 per cent of normal. (8) Noted elsewhere: GRCA had been busy replenishing the rivers with water from reservoirs since May. *****

"Floods like this are also healthy for the river...
Flooding is a natural event.
It can improve the Grand by moving sediments,flushing habitats and
clearing out vegetation that chokes the river."--GRCA (9)


Fast forward to this Jan 08 midwinter thaw: " Heavy rain and melting snow from a sudden thaw generated enough water to reach 80 per cent of the flow that drowned downtown Galt in 1974." The GRCA flood control system worked: "reservoirs meant to restrain floodwaters held back half the water. Weather forecasts were reliable. Dikes and flood plains worked. Public warning systems worked, with some glitches. A dry summer and fall drained three major reservoirs.****** This left plenty of room to store floodwaters, which will now be slowly released." (9) Tucked into the same news report is the following information:  Waste treatment plants, overwhelmed by stormwater, had to drain partly-treated sewage into the watershed, to avoid flooding basements....Brantford closed intake valves downstream, to keep waste and sediments out of its drinking water." (8)

Locally, residents were more concerned about potholes; the impact of this region's rapid growth on Brantford's water supply continues to be conveniently ignored. Potholes, RR learned, are applied physics: "Water gets into the subsurface below the pavement, often through cracks, and expands as it freezes. ...Often water distributes itself unevenly through the subsurface...some areas expand more than others....When the ice melts, the pavement contracts and weakens...add heavy vehicles and the weak spot becomes a hole." (9) Here and there, local streets flooded as sewer grates were blocked by last year's leaves. (10) still to come? burst watermains

“The fact that we’re seeing more and more mid-winter thaws is certainly taking
its toll on the road system”-- Scott Berry, City Kitchener Maintenance Operations (9)


“The changing climate underscores the need to protect flood plains and wetlands.
By keeping buildings out of flood plains,
rivers can flood their banks without fear of property damage or personal injury.
Wetlands play an important role during heavy rains by absorbing large amounts of water and releasing it slowly.”–Joe Farwell, GRCA (11)

Notes: *note during Aug 06 upstream reservoirs supplied 71% water to central corridor; ** same report advises that using closed road voids insurance; *** note drought's impact on groundwater; as we were going through this dry spell, RR attended regional workshop on quantity and quality of water supply; two recognized experts opined that we have an abundance of groundwater but a shortage of infrastructure to tap and distribute same; **** City of Waterloo started running newspaper ads asking their residents to water the City's boulevard trees; ***** significance? a) Cities of Brantford and Caledonia are 100% dependent on Grand River for municipal water supply; b) treated sewage moves into Grand River and requires vast volumes of water to prevent contamination of our water supply; ****** interesting detail: as GRCA indicated there was water left in all reservoirs at end of 2007 drought;

heritage barns: counting public losses, private gains

The Elam Martin farmstead with Georgian farmhouse and Penssylvania bank barn have been saved in RIM Partk for the enjoyment of Waterloo residents.
Grand Magazine profiled a unique home in Kitchener's Deer Ridge whose beauty and wonder lies in its authentic post and beam construction (1) featuring reclaimed heritage fabric from Timeless Materials, Waterloo ON:

hand- picked vertical pine posts and immense interlocking douglas fir beams held together by wood joinery and pegs;interior doors reclamed from a Georgetown estate; another old ornate door from Quebec;four-inch douglas fir floorboards;two-storey staircase: hemlock steps, douglas fir railings;an antique church pew.

From the Timeless Materials website:

Notes: * equal to 20% of total materials that had been offered free of charge to City by JHS at onset of dismantling the barn: wasted taxpayer dollars to purchase scraps of lumber after the best portions had already been sold privately!

**hindsight proves the JHS observation to have been remarkably prescient and that the company is owned by an astute businessman. If this City has lost a priceless heritage, the responsibility rests with the City and not the developer. Sad but true.

*** Other City of Kitchener barns slated for demolition? three to accommodate the Becker Estates subdivision east of intersection of Fischer-Hallman and Huron Roads. The Becker bank barn could be saved as part of a Cultural Heritage Landscape provision; however, Community Services advised the developer that the City has no desire to locate a community park immediately adjacent. Next? a few years down the road? Community Services will determine a need for a Community Centre--but too late as the barn that could have been adapted for such a potential re-use will have been dismantled by Kieswetter/Timeless and the lumber sold to private buyers in Canada and the United States. Unless local residents with vision speak up now before it is too late.

vanishing without a trace


New year's greetings, gentle reader. This week's post will appear in fits and starts between other more pressing commitments. First photo is of a Swiss bank barn structure with silos still to be found on New Dundee Road, on the south North Dumfries Township portion of this regional road.


  1. The Architectural Conservancy of Ontario (ACO) put its spotlight on the barn issue* in the fall 2007 ACORN publication. Herewith a summary of key points made by Leanne Piper in her article, "Our Rural Cathedrals":
    1. The loss of Ontario's heritage barns, silos, drivesheds, milk houses and farm houses can be attributed to these factors: age, urban sprawl, modernization i.e. intensification of agriculture, and the booming architectural salvage market ( hand-hewn timbers and barn boards)**
    2. "Very few municipalities have by-laws or procedures to protect barns, etc....Demolition control by-laws generally exempt accessory or outbuildings and only a select few barns appear on municipal heritage registers in the province."
    3. Essential reading: Eric Arthur & Dudley Whitney, The Barn (1972); Jon Radjokovic, Barn Building: The Golden Age of Barn Construction (2007); R$ L Sommer, The Ultimate Book of Historic Barns, Thunder Bay Press (2000);
2. An earlier article by Sheila Ashcroft, "Barns: Canada's Vanishing Rural Landmarks" expands on this theme:

University of Waterloo Professor of history Kenneth McLaughlin discusses this region's unique cultural heritage in "Mennonite Architecture in Waterloo":


    1. Examples of local heritage barns: 1) City of Waterloo RIM Park Elam Martin Farmstead--German Mennonite Bank Barn; 2) City of Kitchener J. Steckle Heritage Homestead--German Mennonite Bank Barn; 3) City of Cambridge Cruickston stone slit barn ca 1860 (Scottish Full Stone Barn)
    2. Notes: *most were built 1860-1910 when economy was still agrarian-based and experiencing economic prosperity; **locally Timeless Materials, an architectural salvage company, has located its sales centre in an extra large bank barn in North Waterloo.
