About

A digital fishing tool for Pacific Northwest anglers.

Thalweg Fishing brings together the information and tools you use before, during, and after a trip. Check weather and water conditions, plan an outing, record catches and observations, and share updates with your group or selected contacts.

Why it exists

Check conditions, keep a few notes, and plan your next trip.

Checking forecasts and gauges, finding notes from past trips, and organizing an outing often means switching between websites, notebooks, and messages. Thalweg Fishing brings those tasks into one digital tool so you can prepare for a trip, keep a record of what happened, and stay in touch on the water.

Sources you can check
See where readings, forecasts, and reports come from and when they were updated.
Your fishing notes, with the conditions attached
Keep catches, notes, and photos alongside the weather, water conditions, and tides from your trip.
Your fishing spots and records stay private
You choose what to share. Thalweg Fishing doesn’t use your private fishing records for its own research, reports, or recommendations, or combine them with other anglers’ records for those purposes.
Make plans and keep in touch
Prepare for trips, organize group outings, and share updates with your group or selected contacts.

Region

Built for Pacific Northwest rivers, lakes, and coastal waters.

Thalweg Fishing is designed around the region’s changing weather, river conditions, tides, and fishing seasons. Whether you’re fishing a stream, a lake, an estuary, or nearshore waters, it helps you check conditions, plan your trip, and keep a private record of the day.
