Angler briefing

generated · claude-haiku-4-5

Elkton Drift is showing excellent conditions for coho right now, with an exceptional 95/100 score. River flow at 962cfs and water temperature at 12.2°C are both solidly in the ideal ranges, together accounting for 80 points of your score, while overcast skies and moderate wind provide good fishing windows. However, the 62% confidence is notably limited by the absence of current fish count data and recent angler reports, so conditions may be better or worse than this score suggests in practice.
