Report conditions: 143 cfs · ▲ 2.9% 24h · ↓67% median

The Ruby is in excellent shape with clear water at 143 cfs, running 67% below median. Yellow Sally stoneflies and caddis are active, making this prime dry fly territory. Focus on nymphing the deeper runs with Sally nymph patterns and switch to dries during afternoon emergence. Water clarity is perfect despite the slight uptick in flows.
