The Brush Creek Islands

I wrote of this some weeks ago, that there has developed, in Brush Creek, just East of the Plaza, a rather large and impromptu "island"--seriously, an island--in the middle of the creek and that it seems that the city will have to come up with a solution for this one of these days. I think they're going to have to eventually somehow scoop or dredge it out. It's growing rather healthily and quickly, it seems. In addition--and why I write today--is to say there are also, now, little and not-so-little peninsulas also extending out from the creek banks on both the North and South sides of the same creek. Finally, also, and additionally more surprising, is the fact that this last week, I noticed yet another "island" forming, and, again, rather surprisingly quickly, further East of the original island, just short of the large waterfall or drop-off in the creek. It seems Brush Creek is becoming very stagnant East of the Plaza, for whatever reason. I wonder if the city is paying any attention to this. I wonder if the Water Department has noticed. And if they've noticed, do they care? Does it matter? It seems it will, if even just eventually.
