Upper Yough Flow & Release Planner
Live Friendsville flow, Deep Creek Lake level, SafeWaters release schedule parsing, high-water checks, Sang Run estimate, and bubble timing — all in one no-library embed.
Gauge data
USGS NWIS instantaneous values are used first, with USGS OGC latest-continuous fallback.
Deep Creek release schedule
Primary source is the current SafeWaters Deep Creek facility page; the old JSON endpoint is only a fallback.
Lake rule band check
Uses the same monthly rule-band table as your existing calculator and compares only HSD lake readings.
High-water release policy
Planner logic: >900 cfs and rising may cancel; >1350 cfs means no release.
Flow calculator
Formula: (total cfs^0.332) × 0.2417
Bubble timing after release ends
Auto-filled from the active or next release as soon as the schedule loads. Use the buttons above to refresh or override.
