Projects
Fishing ConditionsPublic Tennessee fishing dashboard ranking 170+ waters from USGS, NOAA, TVA, and TWRA
Live at fishing.calvinllc.net. Go scoring engine, PHP app, and Python scrapers in Docker.
- Scores each water 0 to 100 from water temperature, pressure trend, wind, rain, dam generation, solunar timing, and stocking history
- Go scoring engine with species and water-type weights, hard safety caps, and forecast horizons
