How are "THEY" responsible? Well back in June the Three Lakes Water Shed Association at their first meeting in quite sometime, reported that they had successfully lobbied to have the pumps turned off from July 25th thru September. Why anyone agreed to turn the pumps off during the hottest part of the summer just doesn't make sense.
I'm no botanist or biologist but it seems to me that it should be common sense. Warm, stagnant water with little or no current is not conducive for a healthy, thriving, beautiful lake.
Where the water is pumped in from Granby, is deep, cool water that would naturally reduce this growth.
Bottom line, when the pumps are off, Grand Lake clarity is higher but you can see what it does to Shadow. So what happens to Grand Lake when the pumps come back on? Another toxic algae bloom with blame miss placed? Maybe THEY should think things through next time.
