Yesterday I mentioned a dead tree on Fosdic Lake Dam in Oakland Lake Park marked with a Big Red X. I said I assumed the X indicated the tree was to be removed, due to trees not being a good thing to have growing on a dam or levee.A Fort Worth Parks Department person, Mark Woolsey, confirmed the purpose of the X in an email regarding yesterday's blogging, saying,
"The red “X” identifies the tree to the forestry crew for removal. Blogger is correct, a tree growing in the dam generally is not a healthy thing."
I would guess I've been seeing that red X on that tree for at least 2 years. Now, how many trees can you spot growing out of the dam? There are trees growing out of the dam on both sides of the trail that crosses the dam. There are at least 6 trees growing out of the south side of the dam, with maybe a dozen or more growing out of the north side.
Only the dead tree is marked with a Big Red X. Some of the trees are quite large with trunks way thicker than mine.In Dallas, their version of the Trinity River Vision has had a hold up due to concerns about Trinity River levees having been compromised due to trees that had been allowed to grow into the levees.
In the first picture we are at the east end of the dam looking west. In the second picture you are at the west end of the dam looking east. In the third picture you are about halfway across the dam, looking at a thick tree trunk.
You can clearly see there are a lot of trees growing on Fosdic Lake Dam.
Now, the problem with having trees growing into a dam seems rather obvious. Trees have roots. Those roots go deep. The tangle of roots can weaken a dam. Dam fails. Big flood.
Though in the case of Fosdic Lake Dam failing, I doubt it'd be all that big a flood. The water would likely make a beeline for the Trinity River, slowed up by the secondary dam called Interstate 30.So, if, as Mr. Woolsey says, "a tree growing in the dam generally is not a healthy thing," how healthy is it to have 20 or 30 trees growing in a dam, one can't help but wonder.
Very perplexing. I suppose I'm once more raising an unnecessary concern without benefit of verification.
No, I verified there are trees growing in to Fosdic Lake Dam and photo-documented that fact. And I further verified that this is a problem, quoting a Fort Worth Parks Department person's assessment that trees growing in a dam is not a healthy thing.
