Yes.. Strange brew is more the great white north.. what a great movie, eh?! But..what the hey? Close enough.....

ya hoser.
And you've never had any formal training in Limnology, just hubris.Im sure your right about the water colour(color) being from iron,,,
Agreed. looks irony to me too, but what do I know I've never studied lampreys.

I do have a wife who is a limnologist and earned her PhD, in part, studying highly colored lakes in Northern Wisconsin, so I think I have a pretty good consultant on this one if needed.
In lotic waters at northern latitudes wth our predominant surface water pH range of 6-8, Fe complexes with humic and tannin charged organic derivatives. Ferric and Ferrous iron species are largely not evident. The color imparted to these waters is from that portion of the visible light spectrum reflected by these organic complexes, lending a brownish to orange coloration to the water. You are seeing reflected wavebands in the visible spectrum from these humic compounds and lignin derivatives. At snowmelt, conductivity in these streams is quite low, requiring us to shift from magnetic current meters over to mechanical units. We have been conducting surface flow readings for the least three weeks using mechanical meters the vast majority of the time due to dilution from overland runoff sources comprising the vast majority of the streamflow volumes.
I have yet to record a pH value in groundwater this year below 5.8.
http://water.usgs.gov/...ics.html#Conductance Here is a season example of a river system draining igneous derived soils. Our low conductivity flow period is not as extended here in the Lake Superior watershed.
Note the snowpack? Had we moved to the headwaters of this river system and into the spring creeks, the surface sediments would be coated with an orange precipitate which is ferrous hydroxide.
