Green River near Greendale fishing forecast today

Green River near Greendale fishing conditions overview

The current weather inputs produce a good weather-based Fishing Score. Moderate wind should add useful surface movement. A conservative USGS river-flow check reduces the displayed current score by 0.2 points because flow is more than 30% from the seasonal median.

Best fishing time today: estimated windows

The first estimated window runs from 6:33 AM–8:48 AM, around sunrise at 7:18 AM. The second runs from 5:26 PM–7:41 PM, around sunset at 6:56 PM. Lower light can change visibility and fish positioning, but actual feeding periods vary by species, season and water conditions.

Green River near Greendale fishing: structure, seasons and local conditions

Cold tailwater below Flaming Gorge Dam with clear runs, deep pools and a nationally known trout fishery. The forecast becomes more useful when it is read through pools, runs and current seams, together with deeper structure and pronounced depth changes, where depth, current or wind exposure can differ within the same location. Green River near Greendale has tailwater influence. Dam releases can change current speed, depth and water temperature independently of local air weather, which is why fresh flow data deserves more weight than a generic seasonal assumption.

In Utah, spring warming, runoff or reservoir-level change can create fast transitions, while summer usually increases the importance of cooler water, depth and low-light periods. Fall cooling can reopen shallower habitat. For Rainbow trout and Brown trout, the exact timing is better judged from current weather and measured water conditions than from a fixed calendar date. For a river trip, compare the forecast with pools, runs and current seams, together with deeper structure and pronounced depth changes. A rising or falling river can move the best-looking water even when the air weather remains favorable.

Common targets at Green River near Greendale include Rainbow trout, Brown trout, and Cutthroat trout. They do not use depth, current and cover in exactly the same way, so the Fishing Score remains a conditions index rather than a species-specific bite prediction. This page also has a manually mapped USGS reference station, so fresh water temperature, flow or level can be shown when that station reports a supported sensor.

What to watch in today's conditions

Wind

Current wind is about 5 mph from ESE, with gusts near 7 mph. Crosswind and gusts can change boat control and presentation, while bends and protected banks may remain much calmer.

Barometric pressure

Current NWS pressure is missing, so pressure is excluded from this update and the Fishing Score is visibly marked as partial.

Moon phase and light

The moon is currently in the Last Quarter phase with approximately 44% illumination. Lunar illumination has a smaller weight than the main weather factors.

Target species

Always verify current state fishing regulations, seasons, bag limits, licensing requirements and location-specific closures before fishing.

How this forecast is calculated

The Fishing Score starts with National Weather Service weather data: pressure 28%, wind 24%, cloud cover 18%, precipitation probability 18% and lunar illumination 12%. Missing weather factors are never treated as zero; partial weather results are pulled toward a neutral 5/10 according to the missing weight. On eligible river pages, a separate conservative USGS flow check can only reduce the current score when streamflow is unusually far from the long-term seasonal median or changing rapidly. It never increases the score.
