Warming waters has slowed fishing on the Madison River within the Park and made fishing dangerous to any fish caught on the Firehole River. Fall River Basin streams are low, clear, and tend to warm up to the low 60s in deg, F. by late afternoon hours. Stealth is the most important aspect for fishing success on these. Best fishing in Fall River Basin is at Beula Lake, and possibly on all of Park still waters. Traditional and parachute Adams (#14-16) on the surface will get attention of gulpers. When/if wind comes up, switch to small leech patterns.
