Water Quality Maintenance:
- Thermal stratification in Deep Creek reservoir in late summer causes water in the lower strata of the lake to have low dissolved oxygen (DO) content. Water entering the power tunnel comes from the deepest part of the lake, and DO levels in the tailrace can drop immediately after startup. Historically during these times, DO leels may have remained below state water quality standards of 5 parts per million (ppm), depending on DO levels in the lake.
Aquatic Species Protection:
- More than 100 species of fish have been documented in the Youghiogheny River drainage or are thought to have occurred there. Historically, the Youghiogheny River in Maryland supported excellent fisheries for brook trout and smallmouth bass. Due to their relative abundance, brown trout are currently the most important gamefish in the Youghiogheny River from the Deep Creek Station tailrace to Friendsville, MD. Optimal brown trout habitat is characterized by cool to cold water, rocky substrates providing sufficient cover, and riffle-run habitat in combination with areas of slow, deep water. Extreme water temperatures are probably the most important limiting factor to brown trout. The upper limiting temperature to brown trout is 26-27°C/79-81°F.
- The Youghiogheny River is an exceptional whitewater recreation resource and releases from Deep Creek make whitewater boating feasible when natural flows are insufficient. During dry periods, the Upper Yough may be the only whitewater resource in the area available to boaters. Additionally, Deep Creek Lake is the center of Garrett County's recreational attractions. Among the popular water-based activities are boating, fishing, swimming, water skiing and sailing. These activities can be affected by lake levels since underwater hazards may be more exposed as water levels decline. There may also be aesthetic concerns as lower water levels resulting from reservoir drawdowns for power generation result in a greater area of exposed shoreline.
