Current Conditions
Water temperatures are floating around the mid 60s. Tarryall sees significantly less pressure than its bigger neighbors like Spinney and Eleven Mile, but heavy late-summer weed growth lines the shallow banks and inlet areas. Eager stocker rainbows, wild browns, and pike are holding around the weed margins, submerged rock piles, and deep drop-offs near the dam.
Weather:
Short Term -
Daytime highs are running in the low to mid 70s under clear morning skies. Expect wind to pick up around late morning from the north/northeast at 5 to 10 mph, with a 30% to 40% chance of brief afternoon rain or isolated thunderstorms rolling off the mountains.
Long Term -
Standard late-summer high-country conditions stay locked in through the week. Highs remain in the 70s with night temperatures dipping into the low 40s. The typical monsoon pattern keeps daily cloud buildups and scattered afternoon rain showers rolling through South Park.
Tactics:
Rig a two-fly suspended indicator setup using a Frenchie Chironomid or black midge pattern as your point fly, with a Callibaetis emerger suspended 6 to 10 feet down along the drop-offs. If you want to cover shoreline weed edges, switch to a high-visibility terrestrial like a Hippy Stomper with an olive Mini Leech or Callibaetis nymph dropped 2 to 3 feet below. For targeting larger browns and pike, slow-troll or strip an intermediate line along the rock walls near the dam and outer weed lines using black Baby Gongas, olive Slump Busters, or balanced leeches to draw aggressive reaction strikes.
Hatches:
Chironomids dominate the water column, with steady subsurface activity throughout the morning. You will also see scattered Callibaetis mayflies hatching mid-morning, along with damselflies cruising the weed lines and terrestrials like grasshoppers, ants, and beetles blown off the grassy shores during afternoon winds.
Tips:
Focus your energy around the inlet area where cold water from Tarryall Creek pumps in fresh oxygen and concentrates cruising trout. Take advantage of the lighter crowd pressure by walking the shoreline points along County Road 77, casting parallel to the moss beds rather than straight out into open water. Keep an eye on the sky, as afternoon storms move fast over the open valley and create sudden wave chops.
