FLYMASTERWaters
Read the water before you go.
Pick a river or a lake and FlyMaster gathers what the public data says about it today, then turns it into a plan for the day. Your own catches there weigh more than any rule. The same reading, for 407 rivers and lakes in 46 states, is below: find your water.
Conditions
The gauge, the snow, the sky.
The nearest USGS gauge with its flow and thirty days of context. The snowpack at the SNOTEL stations above it against the median. The forecast, the barometer trend, sunrise and sunset, the moon. All of it read on the hour, cached for the drive.
The plan
Where to stand, when, what to throw.
A rules engine reads the conditions the way a guide would and writes the day in steps: the hours, the water to fish, the rig and the patterns in their sizes. On the plan, AI assist sharpens it into a written plan and a hatch guide for this place and date, with your own log on the water in hand.
The map
Waters, access and shops, offline.
Named waters and live gauges around you, public land and access points in forty-six states, your own spots, and the fly shops on each water with their reports. Save a map area and it works with no signal.
Find your water
407 rivers and lakes, 390 of them with a live USGS gauge. Each page has today's flow and the last 30 days, the snowpack that feeds it, what is on the water this month, and the fly shops that know it.
