Hydroelectricity or Recreation?

Bill, yesterday, asked why the hydroelectric plant on Belle Isle was abandoned. Here's Wikipedia's scoop on the matter as well as another excellent question to ponder:

"Silt in river water wore down turbine blades, bearings and bushings. Logs and debris damaged the entrance gates of the mill race and mud had to be cleaned up after floods. Power production varied with river flow and was always low in summer.

In the mid 1950’s the price of oil was so low that petroleum products became the fuel of choice (local gasoline was .25 a gallon). Had anyone foreseen the great increase in costs after the Arab Oil Embargo in 1967, this plant might have remained competitive. Question: would power production have been as valuable as the recreational benefits we now have from a free flowing river?"

Autumnal Sun

Lately, I've been intrigued by the shadows cast by our late autumnal sun.

I am the autumnal sun,

With autumn gales my race is run;

When will the hazel put forth its flowers,

Or the grape ripen under my bowers?

When will the harvest or the hunter's moon

Turn my midnight into mid-noon?

I am all sere and yellow,

And to my core mellow.

The mast is dropping within my woods,

The winter is lurking within my moods,

And the rustling of the withered leaf

Is the constant music of my grief…

~ Henry David Thoreau
