Angler briefing

generated · claude-haiku-4-5

**Verdict:** Elkton Drift rates as fair for Coho right now—worth fishing, but conditions aren't optimal. River flow is performing well in the ideal band, and weather is stable with light wind and good visibility, but water temperature at 22.8°C is significantly above the preferred 8–16°C range, which notably suppresses the score. The 62% confidence is held back by missing fish count and recent angler report data, so local intel on current catch activity would help you decide whether conditions are better than the score suggests.
