If you are the owner of the bottom half of a red Ford Ranger left in Brays Bayou near Wayside Dr. some time in the last 20 years, your vehicle may be waiting for you in HPD’s impound lot. The pilot program intended to test out a procedure for fishing out the 127-or-so vehicles mapped beneath the surface of a few of Houston’s waterways reeled in its 20th and final car over the weekend before the $49,500 project grant ran out.
The removals started near the Wayside bridge over Brays Bayou in late January, then moved upstream of the crossing of Lidstone St. on the 29th; last Friday, operations jumped down to Sims Bayou to score a few final sets of wheels. Harris County Flood Control District, which oversaw the fishing trips, tweeted that project executives will now meet to discuss future removal plans and compare notes on the process, which involved divers from Saltwater Salvage submerging to attach giant yellow floaties to the sunken vehicles:

“My neighborhood flooded in Allison in 2001, and then again on Monday night. I can’t tell you how many ‘so much for the 100-year flood plain‘ comments I heard walking up and down the street.
What it really means is that it is a flood (or more properly a storm, or my favorite, ‘rain event’) that has a 1% chance of happening every year. So what that really means is that if you live in the ‘100 year flood plain’ you have a 26% chance of flooding during your 30 year note. And for many of these areas the 100-year storm on which these maps are based have 100 years or less of accurate rainfall data.
A better rule of thumb is to remember: (1) if you live near a bayou and it rains A LOT, you will probably flood at some point. (2) if it’s raining A LOT and the road you are on dips below the grade of the adjacent roads, it’s probably going to flood and (3) if it’s raining A LOT where you are in Houston, you can count on it flooding.” [
“I’ll bite. Here’s a very simple engineering analysis.
Problems with stream-fed swimming pools in Houston are going to be three-fold:
1) Silt (in engineer-speak, Total-Suspended-Solids or TSS). TSS is treated with 
Just how feasible would it be to build a 3-acre self-cleaning swimming hole somewhere near the center of Houston, so you could take your own bathing-suits-and-skyscrapers pics like the one shown here — without resorting to Photoshop? If enough people donate to the 
“The definition of a ‘spring’ can vary a lot, and is used loosely here.
In Harris County, where the topography is relatively flat, most of our ‘ponds’ and ‘lakes’ are either borrow pits (excavated to raise the grade elsewhere) or dammed-up gullies/ravines along existing bayous. In this case, it is the latter — a gully of Buffalo Bayou that was dammed up, then developed into a neighborhood.
A ‘spring’ is generally a point where the top groundwater table meets the surface. In our area, when we receive a lot of rain, the groundwater table can actually reach the surface. So a spring can range from a trickle of water to a puddle standing on the surface. When I dug the post holes in my backyard for my cedar fence, I hit groundwater at 2 feet deep because of recent heavy rain. In dryer periods, the water table drops, and springs continue to occur along steep cuts in the topography (either along a bayou that has eroded downward, or a man-made excavation). This is not what you find in the Hill Country, where large gaping holes in limestone spew thousands of gallons per hour, sometimes creating rivers out of nothing.
So effectively, any hole in Houston greater than 2 feet deep at some point will become ‘spring-fed.’ During the bad drought of the past few years, most likely the groundwater table dropped and stopped feeding this former gully of the bayou, and the ‘lake’ was most likely topped off by (1) automatic sprinkler runoff and (2) the small amount of storm water runoff they received, as the lake also serves as the neighborhood drainage ditch.” [
