The Jefferson River is currently low, warm, and filled with algae, prompting Hoot Owl restrictions that ban fishing from 2 PM to midnight. Ideal fishing conditions may return in September after irrigation ends, increasing fish activity. For now, anglers should seek cooler waters and wait for the river to recover.

The Ruby River is currently experiencing fluctuating water levels due to irrigation and summer heat, leading to "Hoot Owl" fishing restrictions from 2 PM to midnight to protect stressed trout. July may still offer good fishing, especially with various insect hatches. Specific regulations apply in different river sections.

The Boulder River is still experiencing winter conditions despite the arrival of spring. While fishing is decent, especially with smaller nymph patterns, water temperatures remain low. Anglers are encouraged to explore better fishing spots like Paradise Valley Spring Creeks near Livingston until the Boulder improves in mid-April.
