On 30 September 2021, a team from the California University of Pennsylvania, the Maryland Department of Natural Resources, and the Deep Creek Watershed Foundation sampled selected reaches of Arrowhead Run, a tributary to Deep Creek Lake. Stations were established above and below a wetland to determine its influence on water quality, upstream of the confluence of Arrowhead Run with Deep Creek Lake; and in the cove where Arrowhead Run enters Deep Creek Lake.

Overall, results describe a cool-warm alkaline stream with good chemical water quality, embedded stream bottoms, and very low macroinvertebrate and fish diversity. A wetland near the headwaters of Arrowhead Run had little effect on the water quality of downstream sampling stations. This study is a baseline against which future monitoring efforts can be evaluated.

The Foundation paid $2,470 to California University of Pennsylvania, now Penn-West University. This project partially fulfills Goal 3 of the Watershed Management Plan.
