Report Released for the First Phase of Monitoring after the Yellowstone Club Wastewater Effluent Spill

The Gallatin River Task Force completed a report for the initial phase of monitoring after Yellowstone Club wastewater effluent spill. Data results indicate that Montana health standards were not exceeded at any of the sampling sites during the monitoring period. Aquatic life standards were exceeded for ammonia and sediment.

DEQ Detected Low Concentrations of Pharmaceuticals

DEQ Detected Low Concentrations of Pharmaceuticals

On Thursday, March 3, 2016, a mechanical failure in a storage pond for tertiary treated wastewater discharged approximately 30 million gallons of treated effluent into Second Yellow Mule Creek and subsequently the Gallatin River. The Montana Department of Environmental Quality (DEQ) detected 18 pharmaceutical chemicals and breakdown products in water spilling directly from the Yellowstone Club wastewater pond and 11 chemicals in the downstream tributaries. Pharmaceutical concentrations measured after the Yellowstone Club Spill were below levels predicted to affect human health. DEQ results recorded an anti-convulsant and mood stabilizer, carbamazepine, and an antibiotic, sulfamethoxazole, at levels that could harm fish and stream insects.

How to Collect Fish Population Data

How to Collect Fish Population Data

On Thursday, the Task Force joined a team led by Montana Fish Wildlife and Parks (FWP) to survey fish population on the South Fork of the West Fork (South Fork). Overall, the fish population appeared relatively healthy. Our team found 5 dead trout immediately downstream from the confluence with Second Yellow Mule Creek. Many sculpin showed evidence of fin erosion, related to high levels of suspended sediment carried downstream from the steep slopes exposed below the pipe failure.

Routine Data Provides the Context Necessary to Evaluate the Yellowstone Club Spill

Routine Data Provides the Context Necessary to Evaluate the Yellowstone Club Spill

Recent events have demonstrated the importance of the Gallatin River Task Force Community Water Quality Monitoring Program. Thanks to volunteers like you, the Task Force was able to pinpoint the start and duration of the Yellowstone Club wastewater effluent spill and provide meaningful historical data that is being used to evaluate the impacts of the incident.

Help us continue this valuable work! Join the Task Force at an upcoming monitoring event: April 6th, 7th, and/or 8th to collect baseline water quality data for the Upper Gallatin River Watershed.

Help the Task Force to continue to be the local source for water resource information. Join us April 6th, 7th, and/or 8th to help collect baseline water quality data for the Upper Gallatin RIver Watershed.
