Fishing Reports

Jimmy's All Seasons Angler / Fishing Reports (Page 42)

Stillwater 5/2/14

It hasn’t been a great spring so far if you like to fish stillwaters. We have been blasted with wind so much over the past few weeks it almost feels like somethings wrong if its nice outside! With all the wind, area reservoirs have been churned up more then normal causing the fishing to be a little slower then we would like. The weather looks like its slowly improving, so things should really start picking up in the next week.

Chesterfield- Fishing has been a little slow so far on Chesterfield and this has to do mainly with the wind. Fishing deeper water 12+ft has been best so far with darker leech patterns (Black CB, black mohair leech, Dk. Olive Angora Leech, Brown CB, have been best) and darker chironomid pupa (black bungie buzzer, black sally, summer duck pupa). Fishing should really pick up in the next week or two.

Daniels- Daniels has been the best, most consistent fishing so far this spring. Fishing the upper end with various chironomid pupa (see Chesterfield selection) and bloodworms (holo worm sz10) has been good. For those who prefer sinking lines, fishing with darker leeches and scuds on a type II or III line have been producing as well.

Other Waters- We have not heard much this year from places like Springfield, Hawkins, American Falls, Etc…. Look for all those reservoirs to start really fishing well as the weather continues to improve. We will be sure and update this report as conditions change.

Henry’s Fork 4-29-14

Now is a good time to visit the lower Henry’s Fork. Flows are slightly less than normal, and look for water temps climb to the mid 40s in deg. F by late afternoon.  A good caddis emergence is ongoing and peaking in the afternoon. BWOs are also emerging during the PM hours, especially if weather returns to what it was last weekend. Then there are the ever present midges. March browns should become significant any day.  Don’t put away those streamer patterns just yet; save them for evening presentations.

South Fork 4-17-14

The flow is up to 10,021 cfs from Palisades dam. Some of the tributaries are starting to rise with the beginning of spring runoff giving the water its customary green spring look. Continue using a rubber leg/glow bug combination for the rainbows. Streamers cast on a full sink or sink tip line will be a good technique in these water conditions.

The great feeder canal is still shut down for maintainance so the flow down to Lorenzo is high.

Stillwaters 4-10-14

To our knowledge, all of the reservoirs south of Idaho Falls are ice free and fish-able. The ice seemed to leave most reservoirs early this year so this should be a great year to get more early season fishing in. We don’t have a lot of reports coming in from the various reservoirs yet, but that should change quickly. We will continue to post updates as things change/improve so check back often.

Chesterfield, Daniels, Springfield Reservoirs– with rising water levels and all the wind lately, water clarity seems to vary at these reservoirs day to day. They are all fishing okay, but it may be best to focus on methods that will let you cover a lot of water. Wind-drifting with a full sinking line is a great way to cover water and find fish this time of year! Concentrate on darker leech patterns like a black/olive crystal bugger in a size 8, purple showgirl size 6, and a black or dark olive mohair leech in size 6. Concentrate on the west end of reservoirs which will be warmer than the east side and try fishing a few different depths until you find fish. Fish are scattered this time of year so covering water is the key to success. The one exception here would be Springfield where its probably still a better bet to concentrate on fishing under an indicator with midge larvae patterns (holo worm size #10, Summer Duck pupa size #12,14 and a black sally in size #12,14 would be my first choices). Larvae patterns and pupa will also fish well on Chesterfield and Daniels if you are on some fish. Things are sure to pick up as the weather continues to warm and stabilize. This can be a very hit or miss time of year but its still better than the ice fishing going on at area reservoirs the past few months!

South Fork 4-8-14

The flow increased today to 4331cfs from 3400 cfs. There will be additional increases of 900 cfs each day through Saturday. Generally increases slow the fishing but on some occasions the increases don’t bother the fish. If you are looking for the tagged rainbows these flow increases cause them to start moving onto the redds. Use egg patterns dropped below a weighted san juan worm or rubber legs for the rainbows. There are usually browns and cutthroats hanging around the redds too.

We have included some photos of the diversion above byington that was modified earlier this year. At lower flows there were some power boats that hit rocks at the diversion but the river is high enough now that there shouldn’t be problem for either power and non motorized boats.

South Fork 4-4-14

The flow is now at 3,428 cfs at Irwin. With these increases it might take a day for the small amount of moss and debris that is dislodged to drift downstream.  The overall  water clarity will stay good until much higher flows come later in the Spring.

South Fork 3-28-14

Just a quick note about the flows. The Post Register had an article in Thursday’s paper quoting the Bureau of Reclamation about flows on the South Fork. The Bureau said that the flows were increased several times this week with the last increase coming this morning. Today’s increase brings the river to 2130 cfs which is still a low level. Wading is still very easy.

The water will be very clear again in a day or so and the fishing should continue to be good. Just keep using the same patterns mentioned in the earlier posts.

South Fork 3-26-14

The flow on the south fork has increased some this week. It has risen from 900 cfs to 1512 cfs. The increases could slow the fishing for a day but overall the water conditions should be good for a couple of more weeks.

We have had some very good fishing with a pair of tungsten midges in the deep slow pools. On most days there is a good hatch of midges and we have been using a Harrop’s gray Fluttering midge on the top. In the slow deep pools use a full sinking line with a streamer of your choice.

All of the ramps are open with the exception of Cottonwood/Fullmer which is closed until the access road above the closed sign is officially opened next month sometime by the Forest Service.  The water levels at the ramps are good except at Spring Creek where you have to winch your boat a short distance over the gravel at the end of the ramp.

Main Stem Snake River 3/15/14

Many folks are fishing below American Falls Dam these days taking advantage of low flows.  Fish are concentrated in the low water (400 cfs currently coming out of Dam).  But come April first flows out of the Dam will significantly increased spreading fish around and putting an end to easy access. As with below the Dam, best fishing in the river above is through presenting streamer patterns during low light conditions.

Still Waters 3/15/14

Springfield Reservoir is fishing quite well these days. Try a very slow troll for best results presenting your favorite leech pattern. Also midge hatches during early AM and evening bring fish into a feeding mode. Springfield is currently one of our few ice-free reservoirs, so expect a certain amount of boating company.
