Yellowstone Park

Jimmy's All Seasons Angler / Yellowstone Park (Page 9)

Yellowstone Park 6-10-14

The Firehole River is living up to its reputation as an early season destination with fish responding to PMDs, BWOS, and caddis.  Some giant stoneflies are emerging in the lower Firehole River canyon with wind blown individuals flying above and below. If you visit the Madison Junction area waters in the next few days, consider having some adult stonefly patterns on board. Duck Creek is in prime fishing shape. Runoff is out of it, but leech and woolly bugger patterns work best because post spawning ‘bows and ever hungry brookies look for this source of easy protein so recently abundant.  Ice is off Lewis, Shoshone, and Yellowstone Lakes.

A Park policy which is causing some inconvenience is the necessary and suitable inspection of all boats for invasive species.  Fishing regulations state that float tubes are excluded from this inspection, but it might be best to ask at any entrance or facility what the Park considers to be a float tube. These inspections are performed only at Grant Village and Bridge Bay Marina, and therein lies the inconvenience for boaters coming in the west, north, and northeast entrances.  So for the remainder of this year, at least, put some extra time on the front of your boating-fishing trip into the Park and make sure that the Park agrees with you concept of what a float tube is.

We received a message from Yellowstone Park Visitor’s Service Office that most of the lakes in the Park have much of their surfaces covered with ice.  The Office warns that most of this ice is unsafe for holding any weight and that falling through it would result in immersion in very cold water resulting in a low survival rate.  If you plan to fish any of the Park’s lakes in the upcoming days, consider calling the Visitor’s Service Office, 307-344-2107 or -2109 to determine surface conditions where you plan to visit.

Fishing is good on The Firehole River. Try swinging soft hackle flies through runs. Caddis and BWOs are getting interest from trout. Look for some early PMDs to emerge.  The Madison is high and a bit discolored, but run-up rainbows from Hebgen Lake may strike at a deeply fished streamer pattern.

Park fishing season opens Saturday, May 24th. Between now and then all types of Park fishing licenses and copies of fishing regulations will be delivered to the shop. We will post their arrival in the shop here.

Based on current conditions, look for the Firehole River to offer good fishing for trout responding to BWO and caddis activity.  To a lesser extent the same can be expected on the Gibbon River.  Some early season spawning rainbows will be heading back down the Madison River to Hebgen Lake.  So presenting streamer patterns in the river near the Park’s west boundary could result in an encounter with a trophy rainbow.

The Park re-opened its fishing season three days ago.   Crowds are not up to usual amounts. This means that such popular locations like the Firehole River and the Madison River could be more enjoyable to fish. Streamer patterns will be your best bet for migrating browns in the Madison River. Likewise for migrating browns in the Gibbon River, Gardiner River, Snake River, Lewis River, and Yellowstone River where low light conditions give the best chance for action on each.  Afternoon BWO hatches will dictate how to fish on the Firehole River. If you do not mind the long drive, now begins the fall season on Trout Lake. Colder water will convince lunker hybrids and cutts there to take leech and damselfly nymph patterns.  Make sure you watch the weather in that neck of the woods before you go.

The Park remains closed to fishing, and trespass citations are being issued to persons entering it anywhere.  Currently there is no action by the Wyoming (and Montana ) governor to open the Park as has been done in Colorado and Utah. We will announce any re-opening of Yellowstone Park here.

The Park is closed to fishing for the duration of the government shutdown. Entrances are gated & locked, and technically access from points not at entrance gates are also closed. This includes such as access off the Ashton-Flagg Road, Baker’s Hole Campground, Duck Creek, Grayling Creek, etc.  For more information on the shutdown phone Yellowstone Park Visitor Services Office; 307-344-2107.  When we learn that the shutdown terminates, we will announce  that information here.

Fall River Basin streams are quite low for this time of year, but water temperatures are ideal. Other than tricos, you will not find the large and varied mayfly emergences here the Henry’s Fork or the Madison River offer this time of year.  A few BWOs and even fewer mahogany duns emerge, but terrestrial insect populations will remain strong until the first killing frost.  So go with dry ant, beetle, cricket, horsefly, and hopper patterns.  Try trailing that big hopper pattern with an ant, beetle, or horsefly pattern. Because water is low and sunlight is diminishing, daytime dry fly fishing can be good after water warms to around fifty degrees F.  To be successful, however, you will need all the stealth you have learned from fishing the Harriman reach of the Henry’s Fork and then some because of the smaller water.  But the rewards can be fish ranging to the same large sizes.  Elsewhere, the Firehole River is entering its famed fall season as BWOs emerge while the region cools and days shorten. Run-up browns and ‘bows  from Hebgen Reservoir are coming into the Madison River above and the same will begin soon as Shoshone and Lewis Lake browns will stack up in the river between.  Fall season mayflies are making for good fishing on streams (Lamar River, Slough and Soda Butte Creeks) in the northeast part of the Park. Crowds are down, insect pests are dying off, and cooler weather prevails. It’s a great time to enjoy fishing Park waters.

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.
