August 31st, 2015 North Country Report
Dear Winston,
August 31st North Country Fishing Report
So far this has been a challenging year in the North Country!
  • Weather
  • Low then high water
  • The Green Drake hatch was flooded out
  • The Flav hatch was delayed
Ants provided a few good days in August.
And my favorite fall hatch - The Mahogany Duns are just starting.
Let's hope for a magnificent autumn in the North Country.

'Best of all
he loved the fall'
Ernest Hemingway's autumns in Idaho

Photo by Robert Capa
On a warm autumn day in 1939, Ernest Hemingway stood in the Ketchum Cemetery and methodically read aloud what some local friends believed to be one of his finest works of prose. It was a eulogy for his friend Gene Van Guilder, a publicist for Sun Valley Resort who had been killed in a tragic bird-hunting accident in the Hagerman Valley, near Twin Falls.
"He loved the warm sun of summer and the high mountain meadows, the trails through the timber and the sudden clear blue of the lakes. He loved the hills in the winter when the snow comes," Hemingway said. "Best of all he loved the fall ... the fall with the tawny and grey, the leaves yellow on the cottonwoods, leaves floating on the trout streams and above the hills the high blue windless skies. He loved to shoot, he loved to ride and he loved to fish."

Island Park Outflows to Remain Low

The Island Park Drought Management Planning Committee has agreed to keep Island Park outflows as low as possible for the remainder of the irrigation season to minimize use of reservoir storage and maximize the amount of water available for winter flow.

Outflows will remain below 960 cfs, with small adjustments in the range of 100 cfs made as necessary to keep river flow at St. Anthony around 1,000 cfs. Island Park Reservoir is projected to reach a minimum of 30,000 acre-feet (22 percent of capacity) on September 10.

WR #16, and "The Lower Ranch"
  • Rainbow trout are especially fond of taking nymphs in the surface film.
  • Work individual trout rather than casting to groups, study the riseform and feeding rhythm.
  • Use light and long tippets and a reach cast upstream or downstream for drag free drift with bug reaching the fish before your leader.
  • Patterns with a post or upright wing are easier to see so make a good lead fly with a flush floating dropper.
  • Work current seams, slow, shallow margins around plants and weeds.
  • Use a low profile and casting angle, keep false casts away from fishing area.
  • On the delivery, place only the fly and tippet in front of the trout. Do not let your fly line land close to the trout, or it will spook.

Yellowstone National Park had the highest recreational visitation on record in July with 980,702 visits for the month-a 14 percent increase over last July and a 2 percent increase over the previous July record in 2010. 
For the first seven months of 2015, record breaking recreational visits totaling 2,279,557 are up 17 percent over last year and 13 percent over the previous record year in 2010.

Visitation statistics are calculated by taking the actual number of wheeled vehicles entering the park gates, and using a person-per-vehicle multiplier to calculate the number of monthly recreational visitors.  
July is typically the park's peak visitation month, followed in order by August, June, September, and May. 
Detailed park visitation information and additional information on how these statistics are calculated is available online at https://irma.nps.gov/Stats/Reports/Park.
