What the water readings mean

Every fishing report on Hooked Fisherman opens with a Current Conditions panel — water temp, flow or tide info, moon phase, and a short weather line. Those numbers come straight from NOAA buoys and USGS stream gauges, not from us. They're useful, but only if you know what they actually tell you about how the fish are likely behaving. Here's the plain version.

Water temperature (°F)

Water temp is the single most useful number on the panel. Fish are cold-blooded — their metabolism, where they hold, when they spawn, and what they'll chase all key off it. A change of a few degrees flips patterns: pre-spawn vs. post-spawn bass, a striper run arriving or leaving, trout retreating to deeper holes when the river warms past 65°F.

Rough freshwater anchors for the lower 48: largemouth start chasing in the high 40s, spawn in the 60s, slide deep in the high 70s. Trout fish best in 50–65°F water and start to stress past 68°F. Striped bass inshore migration ramps up around 50°F. Use the reading as context, not a strict rulebook — air temp, time of day, and recent weather all shift the fish's actual world.

Flow (cfs) — freshwater

Cubic feet per second.One cfs is roughly a basketball-sized volume of water passing a point each second, so a stream running at 50 cfs is wadeable; a river at 5,000 cfs is moving real water. The absolute number matters less than the trend. A river that's been at 200 cfs all spring and suddenly jumps to 1,200 cfs has muddied up and pushed fish to the banks. Same river dropping from 200 to 60 cfs has cleared up but exposed fish — they get spookier, downsize your tippet.

For tailwaters (rivers below dams), cfs is also the dam's release schedule — you'll see big swings on a daily clock. Wading windows live in the low-flow hours.

Quick read: rising flow + falling clarity = move closer to the bank with bigger, louder presentations. Falling flow + rising clarity = longer leaders, lighter line, smaller flies.

Tide / current — saltwater

Saltwater fishing is mostly a tide game. Moving water concentrates bait, which concentrates predators. The two best windows on most coastlines are an hour either side of slack — when current is building, not when it's ripping or dead. The tide info on each report points to the relevant phase and any current/wave context from the nearest NOAA buoy.

Spring tides (around full and new moons) move more water and produce stronger runs. Neap tides (around quarter moons) are slower and gentler. Neither is "better" — they fish different.

Moon phase

For saltwater, moon phase is mostly a tide-strength signal — full and new moons make spring tides, quarter moons make neaps. For freshwater, the big effect is at night and around dawn/dusk: bigger fish (especially stripers and large bass) feed harder around full moons. Day fishing on a high pressure system after a bright moon night is often slower than average — the fish already ate.

Weather summary

One short line summarizing sky, wind, and any pressure trend that's relevant. The piece worth paying attention to is the trend, not the current state. A falling barometer ahead of a front often turns fish on; a high-bluebird day post-front often shuts them down for a few hours.

Buoys and gauges — what we're reading from

Saltwater readings come from NOAA National Data Buoy Center stations — fixed buoys and coastal stations reporting wind, wave height, water temp, and pressure on a clock. Freshwater readings come from USGS National Water Information System stream gauges — flow, stage, and water temp. Both data sources are public and live; the values you see on a report are typically within an hour of real-time.

One caveat worth keeping in mind: a buoy or gauge is one point in space. Big bays and long rivers warm and cool unevenly. The reading is a reasonable proxy for the surrounding region — not a guarantee for the specific cove or run you're fishing.
