Not much has changed in fishing or water conditions. The weather keeps working against us. It isn't relieving snowpack problems and creating warmer temperatures for better insect hatch consistency. As for snowpack, in all my years in Sun Valley I've never seen this much water content (209%) in the mountains yet to melt, at this late date. The fishing, as limited as it is, has been spotty, spotty and spottier. Your results depend on where you are and when. Hopefully there will be a vast improvement in the weather this week and maybe even a touch of summer. As of now, fishing conditions are short and simple so let's have a look at the week to come.
SILVER CREEK—Still the only game in town, but inconsistency is the name of the game. The Preserve has been weak. Downstream things seem to improve with hatches or lack thereof, the deciding factor. With warmer weather and the absences of rain this week, things should improve greatly. Pale Morning Duns, Beatis (spinners) and Midges are seen and imitations of all will be needed for success, depending upon where you are casting a line. PMD Parachutes #16-18, Cripple and Emerger PMD #16-18, Pheasant Tail Nymphs #14-16, Beatis Parachutes #20-24, Mason Quill Beatis Spinner #20 and Black Para Midge and Pupa #20-22 should all work where and when appropriate. Ant and Beatle patterns #16-18 have also been effective. As of this writing (Monday, June 13), the Brown Drake is late and has yet to appear. It will come but it will do so in a rush and be over before you know it. At this point, the emergence and spinner fall will be a bit of dice rolling and might even be seen midday, which is not that unusual. I doubt that much will be seen past the weekend but with this year's screwy weather, I for one, will not place a bet on it or anything.
BIG WOOD RIVER—Not fishable and won't be for some time to come.
WARM SPRINGS/TRAIL CREEK—Out of shape for fishing.
BIG LOST—Upper river is running high but the river below the reservoir is running low (300 cfs) which is highly unusual and unimaginable for this time of year. Clearly, the irrigators as of yet, do not need the water but that will change. The problem is, we never know from day to day, when the call for water will come.
PENNY LAKE/LAKE CREEK/GAVER'S LAGOON—Planted regularly with fish and great for kids.
SOUTH FORK OF THE BOISE—Still high and holding at 4000 cfs which is for floating only (maybe???) and not for wading.
