Lake of Legend to be Rehabilitated

24 December 2011

Lake Minnehaha has a plan for a fix-up:

The waters of Lake Minnehaha, at 6.5 surface acres in the middle of the park, are stagnant. There isn’t enough movement and so it provides a perfect habitat for blue-green algae. In hot weather, it dies and produces the putrid smell.

This particular algal species can at times be toxic, killing dogs that drink it or sickening people coming in contact with it. It spreads on the water surface and blocks sunlight that would otherwise encourage growth of healthy organisms. Storm water runoff brings in more gunk and debris.

Good news for Ontario’s Lake of the Woods is that phosphorus levels may be getting less:

Contrary to popular belief, the phosphorous rates in the Lake of the Woods might be in long-term decline.

According to a study by Kathryn Hargan that appears in the December issue of the Journal of Great Lakes Research, declining industrial pollution and increasing shoreline development on the lake is combining to have a lesser effect on the lake than is publicly perceived.

Although the concentrations of phosphorous in the main channel of the lake are twice those of other Ontario lakes, her report alleges increased algae blooms are evidence of the effects of climate change, not increasing phosphorous.

In Rhode Island, environmental violations are now being posted on-line:

There are 503 open cases for alleged environmental violations across Rhode Island. The number may seem excessive, but officials say the case load has been constant in recent years. A more pressing concern is the drop in the number of investigators the state Department of Environmental Management (DEM) now employs to investigate infractions.

A list of EPA completed enforcement actions by year for air, water and hazardous waste violation is available here. The EPA and DEM resolved some 47 local cases in those three categories during the past year.

Over in Kashmir, on the sub-continent, over 4000 bar headed geese have arrived at the Gharana wetland nature reserve.
