Upper Yough release planner
Check the next Deep Creek release, estimate the level at Sang Run, and see when the extra release water may pass downstream.
cfs = flow in cubic feet per second. ft = gauge height or lake elevation, not water depth.
Estimate the Sang Run level
Add the Friendsville flow and expected release flow to estimate the gauge height. You can fill the inputs from live data or enter your own values.
Enter both flows as zero or greater. Use 0 for the extra release flow if no additional water is being released.
Calculation method
Sang Run height in feet = (combined flow in cfs)0.332 × 0.2417. This is an estimate on the local gauge scale, not the depth of the river.
Deep Creek release schedule
Choose a release to estimate when the extra water will pass downstream. Confirm the schedule with SafeWaters.
When the release water moves downstream
The “bubble” is the extra water from a dam release. These approximate times count from when the selected release ends.
Could high water affect the release?
This planner flags a possible cancellation above 900 cfs when flow is rising, and no release above 1,350 cfs. Confirm actual operations with SafeWaters.
Recent gauge readings
Observed river flow and lake level. Check the timestamp beside each reading.
River flow at Friendsville
Dashed lines mark the planner’s 900 and 1,350 cfs release thresholds.
Deep Creek Lake elevation
Dashed lines show the stored upper and lower operating limits and lake cap. Lake heights must use the same reference for comparison.
Lake operating range
Compares the lake level with the monthly operating range stored in this planner. HSD is the lake height reference used for this comparison.
