Westheimer Parkway, Clay Road reopens, some roads still closed after weeks under water

Addicks, Barker Reservoirs continue to drain 3 weeks after Harris County floods

Harris County and City of Houston officials announced Tuesday the reopening of Westheimer Parkway through Barker Reservoir (from FM 1093 to South Fry Road), and Clay Road through the Addicks Reservoir (from State Highway 6 to Brittmore Drive), providing some relief to heavy traffic conditions caused by those closures.

The sections of those roadways that run through the storm water detention reservoirs have been impassable due to high water for about three weeks, after the Houston area flood disasters in April. The rainfall flooded west and northwest Harris County and filled the two reservoirs to record levels.

Since the Tax Day storm passed, the U.S. Army Corps of Engineers, Galveston District, has been releasing a steady flow of storm water from both flood control facilities into Buffalo Bayou in an effort to lower water levels in the reservoirs. This has resulted in the pool levels in the Addicks and Barker reservoirs dropping several feet, which has removed standing water from neighborhood streets behind the Addicks Reservoir and now from Clay Road and Westheimer Parkway. 

Motorists are advised to continue driving with caution on Clay Road and Westheimer Parkway as roadside ditches along both roads remain full of water.

The remaining roadways that run through the Addicks and Barker reservoirs that are underwater and impassable include:

Addicks Reservoir:
• State Highway 6 is closed from Clay Road to Park Row.  TXDOT encourages motorists to use FM 529 as an alternate.
• The north-south North Eldridge Parkway is impassable from Dairy-Ashford to Clay Road.
• The east-west Groeschke Road is impassable from SH 6 to Barker-Cypress Road.
• Other internal roads in the reservoir, including Patterson Road, Bear Creek Drive and War Memorial Street, are impassable.
• All recreational facilities are closed.

Barker Reservoir:
• South Barker-Cypress Road from Westheimer Parkway to FM 1093 is impassable.
• All recreational facilities are closed.

Officials say sections of SH 6 and North Eldridge Parkway that have been closed for weeks should be open to traffic by this weekend. The section of South Barker-Cypress that has been closed through the Barker Reservoir should be open sometime next week. Transportation officials will monitor conditions on those major roadways closely, and will only reopen them after they have been inspected and deemed safe for the travelling public.

All road openings are subject to change if there is additional rainfall in north/northwest Harris County. It will be several weeks before both reservoirs have drained all storm water from the Tax Day Storm, any additional rainfall could lengthen that process.

To expedite the emptying of the reservoirs, the Corps Galveston District has increased storm water releases to Buffalo Bayou by as much as double the normal release rates, which has caused Buffalo Bayou to flow several feet higher than normal from State Highway 6 through downtown Houston.  These bayou levels have been significantly lower than the water levels on Buffalo Bayou during the April 17-18 flood.

Public recreation areas along Buffalo Bayou downstream of the dams that are being impacted by increased releases include the low-lying areas in Harris County Precinct 3's Terry Hershey Park, which is located along Buffalo Bayou from State Highway 6 to the West Sam Houston Tollway, and Buffalo Bayou Park on Buffalo Bayou between Shepherd and Allen’s Landing just west of downtown. Property owners along the bayou will also notice the higher levels.

Park users and residents who live along the bayou are urged to use caution when venturing into those parks and all areas along the bayou's banks, as there will be higher than usual bayou levels for the next several weeks:
• From State Highway 6 to Piney Point Road the bayou may be up to 5 to 6 feet above normal release levels and some low-lying trails in Terry Hershey Park will have water on them.
• From Piney Point Road to Loop 610, the bayou may be up to 4 to 5 feet above normal release levels.
• From Loop 610 to downtown, the bayou may be up to 3 to 4 feet above normal release levels and there could be water in low-lying sections of Buffalo Bayou Park.

SAFETY ALERT: Residents are advised not to drive or walk into high water on streets; nor to boat or swim on Buffalo Bayou, or any bayou or creek for that matter. Bayou and creek water levels are high throughout the county and their currents are swift and dangerous.
