Approximately 25,000 litres of diesel spilled into a stream that feeds the Red Deer River, according to the latest update from Alberta Environment and Parks.

The incident occurred on June 9 when a semi truck carrying the fuel rolled over on Highway 21, south of Nevis, Alta.

Some of the fuel reached the Red Deer River, which provides drinking water to some communities. In a written update, the province said a "significant amount of the product appears to have been contained in the stream course."

Results from surface-water tests are expected on Saturday. 

Plans submitted

"Impacted fish and wildlife have been observed in the immediate spill area," reads the government update. "A visual assessment in the Red Deer River has identified minimal visual evidence of product and no impacted wildlife along the river at this time."

Stettler, which pulls drinking water from the Red Deer River, continues to use its reserve water supply.

The company responsible for the spill has submitted a wildlife response and a sampling plan to Alberta Environment and Parks, which approved both. An aquatic assessment plan is still being developed, according to the province.
