Decisions to open or close waters are made on Monday for fishing Tuesday/Wednesday, Wednesday for fishing Thursday/Friday, and Friday for fishing Saturday/Sunday/Monday. Since decisions are made 1-3 days before the status is effective, forecasts are used rather than real-time flows. Like any weather forecast, these predictions have a margin of error, so the status of waters may not always align with current flows.
