Pulling the latest USGS reading.
Four tabs, the same ones you see in the app. Pick a river, and DriftLogic does the reading for you.
Pick your river and your gear. DriftLogic reads the USGS gauge and builds the whole rig, with the reasoning behind each choice.
Every river's live gauge on the map, plus curated access points from Metroparks, ODNR, and PA Fish & Boat sources.
Two taps saves the fish with the exact flow, temperature, clarity, and light, plus the rig you built.
Star the rivers you fish and see them side by side: prime-flow status, trend, temperature, and a 7-day flow chart for each.
A local guide to fishing the Rocky River from late September through April: where the fish hold, how long the clay takes to drop out, and whether today is worth the drive.
Flow, clarity, and time since the last rain decide the day. Clay holds in suspension far longer than silt or sand, so expect two to four days of stable, dropping flows before the river fishes again after a real storm.
Steelhead will bite in water that is too high. They rarely bite in water they can't see through. Watch the gauge fall, not the number alone.
Glacial clay in the upland soils is why the river runs chocolate after rain. Two feet of visibility is plenty; six inches is not.
Low-level bridges along the Valley Parkway close during high water. When the bridges are closed, go home.
Fish enter the system as early as late September in good water years and run actively through April.
Fish stage at the mouth and move up on the first sustained rain. Warm water, low flows, spooky fish.
The best mix of numbers, water temperature, and aggression. Also the most crowded, so fish weekday mornings.
Slow, deep, and technical. Fish hold in sand pockets beside shale ledges. Slush ice shuts it down.
Snowmelt bumps, rising temperatures, and fish on gravel. Leave spawning fish alone and work the water below them.
Check the gauge, get the rig, and drive to the access point, all from your iPhone. One purchase, and it's yours.
