75°F: in the optimum range for largemouth bass and channel catfish
Fisheries research puts the optimum for largemouth bass and channel catfish at this temperature. It says how they would grow and feed if they live here, not how many you'll catch. At 73°F and up trout stop growing, so give them a rest. We don't list which fish live here yet.
- Water 75°F at W Fk Trinity Rv at Grand Prairie, TX, 7.3 mi away, as of Wednesday, Oct 28, 5:30 AM CDT.
- Season: fall.
- Waning Gibbous, 83% lit; solunar major 3:10 AM–5:10 AM and 3:43 PM–5:43 PM (folklore, see below).

Where 75°F sits for common freshwater fish
Temperature ranges from fisheries research. They describe how the fish feed and grow, not a catch forecast, and they don't apply to salt water. We don't yet list which of these live in River Legacy Parks; check your state's fishing guide.
- TroutToo warm
73°F and up: trout stop growing and are stressed. Montana restricts afternoon fishing on streams that reach 73°F three days in a row.

Moon and solunar times
Thursday, Oct 29 · Waning Gibbous, 83% lit · times in CDT
| Window | When | Centered on |
|---|---|---|
| Major | 3:10 AM–5:10 AM | Moon overhead |
| Minor | 11:19 AM–12:19 PM | Moonset |
| Major | 3:43 PM–5:43 PM | Moon underfoot |
| Minor | 9:07 PM–10:07 PM | Moonrise |
Anglers swear by solunar tables: the idea, popularized by John Alden Knight, is that fish feed most when the moon is overhead or underfoot (major windows, about two hours) and around moonrise and moonset (minor, about one hour). The moon times are real astronomy; the evidence that fish keep to them is thin. Treat them as a fun tiebreaker, not a forecast.
Sources: water temperature from USGS; species ranges from the sources linked on each card. Moon times are computed from standard astronomical formulas and agree with the US Naval Observatory to within a few minutes. A fishing license is required; check local regulations before you go.
