Take note of these thoughts. Fresh water is precious and that means the powerful have their eyes set on controlling it.
Water headed toward a tipping point? The Colorado River is in dire straits, Great Lakes states are resting on past accomplishments and the federal government is non-functional.

Only 20 to 30 years ago, environmental reporting was sharp, held government and polluters accountable, and resulted in policy changes. Not much of that anymore.

Detroit's renaissance following the 2013 bankruptcy continues. But its "vital and iconic" river remains mired in 1950s pollution.

Detroit is back from the depths, its river is mired in the 1950s
The Detroit River is often referred to as "vital and iconic" while its cleanup is not a priority as leadership lags.

After three days of rain, clearing skies over Grand Traverse Bay are welcome.

The Great Lakes are one-fifth of the 0.3% of the Earth’s freshwater that is at the surface. Another way of looking at it: freshwater is scarce, and the Great Lakes must be carefully conserved.

Sunday night moonrise over the west arm of Grand Traverse Bay.

The Great Lakes are magnificent and this is all true – – except that we are talking about percentages of surface freshwater. Not of all the freshwater in the world. A lot of water is underground and locked up in ice. But six quadrillion gallons of Great Lakes surface water are nothing to sniff at.

Evening on the bay, where things make sense.

Lake Superior--the largest lake by surface area in the world--compared to the east coast.

The Great Lakes have more shoreline than the East Coast.
