Yellowstone Park 9-7-13

Not much change here except that severe thundershower can slow fishing, especially on streams flowing through erosion prone banks.  The Snake River and the Lamar River are susceptible to this problem which can put down fishing until after water clears.  So its a good idea to check weather forecasts when we are in a monsoon mode.   For now AM trico spinner falls make for good fishing on most streams.  Ant flights make for good fishing on Fall River and on Beula and Hering Lakes.  Switch to terrestrial patterns including those for spruce moths for mid day and afternoon fishing.  With shorter days and cooler nights coming on, look for fishing to pick up on the Firehole River.   Want some action for sure but without  many large trout? Try Beula or Riddle Lakes.  Try Obsidian and Indian Creeks.   Want to try a small stream hosting large trout? Try Boundary, Duck, Mountain Ash, or Soda Butte Creeks.
