Kern River Fly Fishing Report December 12, 2017


Upper Kern 20 Mile Section (north of Kern River Fly Shop)The upper Kern River from Lake Isabella north to 4 miles past the Johnsondale bridge( wild trout section) remains open to fly fishing all year. Water temperatures have dropped down to 40 degrees in the morning and warming up to 44 degrees in the afternoon. The fishing is slow early in the morning in this section, but turns on later in the day, around 2pm. A slight BWO hatch occurs around this time and Rainbows are looking up in some areas. Nymphing  or using a dry dropper rig during the other times is producing a fish here and there. Please check out the video below.


Lower Kern River below Isabella Lake – Water temperatures down here are 5 to 10 degrees warmer The DFW stocked the lower river recently and fly fishers have been doing well on hatchery fish in this section. The lower Kern has been fishing fair for bass at this time from lake Isabella dam to Bakersfield/Oildale.
Lake Isabella – Ok for Trout, fishing slow for bass and carp

All tributaries in Tulare County are closed until the last Saturday in April.

Upper Kern 20 Mile Section

Flows on the 20 mile section are dropping every day and the river continues to fish world class as many rainbow are being caught up and down in this section. This is the time to start fly fishing this section as water temps are holding around 60 degrees and rainbows are very active. There is a PMD Mayfly hatch around 7:30pm in this section and the fish are very aggressive at this time. Streamers are working well casting down and across and stripping back up stream in the seams. Below are some links to flies we are using at this time.

Upper Kern Fly Fishing Report

Anglers! With the large amount of rain and snow pack we have received over the past couple of months, the Upper Kern River is definitely running strong at approximately 3,100 CFS.  Over the past couple of weeks, the question we have been asked the most is: When is the Upper Kern going to be safe for fishing? While this is a difficult question to answer, we are looking at mid-June, closer to July, August and September. In the past, these have been difficult months to fish due to the low water levels, but Mother Nature has changed the forecast drastically.


While we do not recommend fishing the Upper Kern in these conditions with the flows so high, there are the few that will not take no for an answer. If you must fish,  stay out of the water and fish along the banks with heavily weighted nymphs and a sinking leader. Who knows, you may land one of those great trophy trout or as     Mr. Humphreys did a couple of weeks ago, a Native Sacramento Pikeminnow.

Lake Isabella

With the Upper and Lower Kern pushing the limits with record breaking flows, we are fortunate enough to have an alternative location to fish: Lake Isabella.  With the massive influx of water, which we have not had in the lake since May of 2007, these conditions are bound to create a healthy habitat and grounds for the fish to become extremely active. At the present time, here you will come across trout, bass, crappie and even carp, which are a challenge to land on the fly!

Come see us at Kern River Fly Shop and we will get you set up with some bass and crappie flies.  Or, CLICK HERE TO SUBMIT AN ONLINE ORDER and we will pick them out for you. Oh, and do not forget your float tube! If you do not have one, don’t worry! We have some at the shop for purchase or rental!

Lower Kern

Stay far, far away from the Lower Kern, unless you are an extreme kayaker. The flows are around 5,000 CFS and extremely dangerous at this time.

Forks of the Kern

With the current flows and forecasted run off, it is going to be a couple of months before we can even access the Forks. In the meantime and after April 30th, try hitting up some of the smaller streams, creeks and tributaries running into the main Kern River.
