## River Rat Description
Montana rivers don't wait. River Rat gives paddlers, fly fishers, and rafters a clean read on 39 rivers across Montana and Idaho – before you load the truck.

Know if it's runnable, not just the CFS number.
Live readings are automatically classified: too low, bony, ideal, pushy, too high. You see the verdict, not just the number.

Plan a trip, not just a day.
Save your rivers. Open the Trip Planner, pick a date, and see which runs will be in shape. The weekend digest gives you the one-line read before you open anything.

Hatches: type, timing, and fly patterns.
Active, approaching, and fading windows by species – salmonflies, PMDs, caddis, and more – with fly patterns and timing notes built around water temperature, not calendar guesses.

What's in the detail view:
• Real-time water temperature + fish thermal stress alerts (67°F stress, 70°F danger)
• Water clarity signal with 24-hour trend
• Gage height
• Rapids and hazards with class ratings
• 7-day weather: air temp highs/lows and precip probability

Set alerts. Stop babysitting gauges.
Set a threshold – "notify me when the Blackfoot hits ideal" – and let it fire when conditions land. No polling required.

Everything saves locally.

39 rivers across Montana and Idaho. Built for the people who actually run them.
