A day or so ago RTB posted a message about leaves and algae blooms in the 
lakes.  Offline, I corresponded with RTB and promised I would examine a 
storm sewer outfall during my next walk.  This afternoon I examined the 
outfall on the north side of Lake Harriet.  At the time a park board was 
working to reinforce the shoreline berm against washout and had been 
dredging around the outfall.  I asked whether a big slug of leaves had 
been there and the crews answer was 'no.'  So, if leaves have been 
entering the storm sewers during the past leaf fall, it appears that not 
many have reached the lakes.  I suspect the leaves that have entered the 
storm sewers are sitting down there rotting away - next spring when the 
snow melt-off and rains flush the sewers I would expect that juicy, 
nutrient-rich brew to enter the settling ponds.  Look for lush growth.  
Would it be against any rules to sprinkle some of my surplus Gray 
Conehead wildflower seeds (year 2000 harvest from my front yard) around 
the edges of the settling ponds.  They make for heavy masses of yellow 
flowers from August through September.
