WAIT, DID THE 2008 RECESSION UP THE CHANCES OF A FUTURE HOUSTON CHEMICAL CATASTROPHE? Predicted Before and After Flood Map, 500 Year Flood EventRoy Scranton imagines “a wave of water sweeping toxic waste into playgrounds, shops and houses” in Magnolia Park in his op-ed this morning, written after touring the Ship Channel and speaking with the local A&M and Rice research teams pushing for variations on a series of region-scale coastal barriers to hunker down behind whenever the next gigantic hurricane hits the Houston region, in hopes of avoiding deadly flooding and catastrophic chemical spills. But the researchers tell Scranton that pushing for federal and state funding for a response is a slow endeavor; Jim Blackburn (a main player on the Rice team) tells Scranton that he’s “heard more than one person say our plan is to wait until the next hurricane comes, then depend on guilt money from Washington to fix the problem.” Scranton writes that the best chance for that guilt money so far might have been in 2008, when Hurricane Ike landed just 30 miles northeast of the zone that modelers say could have caused thousands of deaths and irreparable ecological devastation to the area, on September 13th — 2 days before the Lehman Brothers filed for bankruptcy, pulling global attention and national funds to other issues as markets began to crash.

A water-watching reader sends some south-facing photos from yesterday evening (right) and last October, comparing views over the fenceline of the 400-ft.-wide diversion channel at the northern edge of the Addicks reservoir. The channel picks up most of the flow from Langham and Horsepen creeks where they join up as they flow south into Addicks. The 400-ft.-wide floodway was dug in the 1980s; the flow usually lurks down in the narrow channel seen in the shot on the left.

The scene above is less than a mile east of Bear Creek Village, where water is now moseying into neighborhoods from the western edge of the reservoir (and washing some wildife and livestock around). The Army Corps of Engineers has been releasing water from both Addicks and Barker dams to minimize the pooling (and relieve stress on the dam structures themselves) — but those releases have to be done slowly enough to avoid causing additional flooding downstream along Buffalo Bayou. Meanwhile, water is still flowing into the reservoirs from western watersheds; the measured levels behind the 2 dams topped all previous water level records and normally allowed pooling limits in the reservoir by Tuesday, and has been rising since. Here’s a shot of water gushing out through some of the gates of the Barker dam this afternoon:
