This is one of the most amazing political, knee jerk reactions I have ever seen in my lifetime. While I really felt for all the losses my friends and neighbors on the northern end of Lake Houston experienced, where is the science behind this decision?
The crest in the Oct 1994 flood at the Lake Houston Dam was the exact same at 52.8’ as the August 2017 flood, however the crest at at the West Fork of the San Jacinto river near Humble was 2.4’ higher. While the 1994 flood caused a flooding damage in 1994, the additional 2.5’ last year impacted several order of magnitude more families.
In the ‘94 flood Lake Conroe reached a max discharge rate of 39,000cfs. In the 2017 flood, they reached a discharge rate of 79,000cfs. What I find really disturbing is they dropped the Lake Conroe water level at the dam by ~2.5’ foot in ~36 hour period as Kingwood was going under water. They were down to 1’ above normal pool level within 4 days so the Lake Conroe folks could get back to normal. Do you think the tragedy in Kingwood had anything to do with Lake Conroe release rates? Once they dropped out of the high level alarm, why not maintain until other floodwaters receded downstream? Instead they deflect trying to skew the facts.
I wonder if any consideration was given to the impact this decision would have on the Lake Houston fishery during the spring spawn or the other Lake Houston area residents who were left high and dry?
I am at least happy to read on City Councilman Dave Martins Facebook page, they have decided to maintain normal pool level of 42.5’ with the level lowered to 41’ ahead of significant events instead of the 40’ as they did this week, however I have not been able to find any facts confirming this as fact.
Meanwhile Montgomery County Commissioners Court has passed resolutions and are fighting any Lake Conroe Pool level reduction on the basis of causing $1,000,000,000 of property value losses. As usual with most things follow the money.
I do agree dredging of the West Fork and the mouth of East Fork and Luces Bayou with possibly widening the channels at FM1960 would reduce flooding on the River, however based on readily available data and a little common sense, it is easy to determine the 2017 flooding was as simple as the fact you can only open a faucet so much before water starts backing up in a sink. If you don’t pinch on the faucet flow the sink will fill up and run over.
