All watersports activities at Dallas White Rock Lake are closed after a construction crew breached a sewer line and sent more than 1 million gallons of untreated, raw sewage to White Rock Creek.

From this area, White Rock Creek winds its way 12 miles through Plano and North Dallas to its confluence with White Rock Lake. Texas Sky Ranger flew over the creek on Thursday and noticed several dead, swimming fish in the creek.
Officials with the NTMWD confirmed that drinking water is unaffected and that White Rock Lake is not a water utility for Dallas Water Utilities. The immediate risk to humans and animals is to come into contact with the untreated wastewater. As a precaution, the Dallas Parks and Recreation Department closed all water activities at White Rock Lake, including the dog park, on Thursday afternoon. The Texas Commission on Environmental Quality and the Texas Parks and Wildlife Department are planning to conduct evaluations of the creek and lake ,

Water district officials told NBC 5 that dry weather and no rain in Die Forecasting can help to slow down the progress of the sewage and make cleaning easier.
"The district and entities are examining how far this wastewater has flowed into the stream and what type of cleaning and rehabilitation is required," said Denise Hickey, with the NTMWD. "We have no time line, how long it will take for this river to actually reach White Rock Lake."
The Dallas City Councilman, Mark Clayton, said he had learned of the overflow on Thursday morning and warned that the sewage could flow downstream in Dallas and White Rock Lake, causing a fish death, unpleasant odor and restriction of marine activities and Access due to potential health hazards.
"I just found out there was a chemical spill yesterday in Plano that has potential to influence White Rock Lake and Creek," Clayton wrote on Facebook. "The staff monitors the situation, but it may require the closure of the dog park with selected activities on the lake with great caution."
The average pool holds about 20,000 gallons of water – the estimated volume of burial of the NTMWD is 50 times greater.
