VIDEO: Is the Kern River Fishing Any Good Right Now?

Late August is a transition period on the Kern River. The hottest part of summer has not quite let go, but the rhythm of the canyon starts to shift. The busiest family travel period is winding down, weekday pressure on the Upper Kern eases, and the Lower Kern begins to offer a different kind of fly-fishing day altogether.
For anglers visiting Kernville, that creates an interesting choice. Start early and fish the Upper Kern for trout while the water is coolest, or head downriver and explore the bass water that comes alive as summer turns toward fall. Both can be rewarding, but each calls for a different plan.
Upper Kern Trout Fishing: Let the Clock Set the Plan
On the Upper Kern, timing is everything during the hot stretch of late summer. In the video, early-morning air temperatures are near 70°F, while the afternoon is expected to reach 100°F. The report recommends getting on the water at first light and fishing until around 10:00 AM, before the heat raises water temperatures and trout become less active.
The catch-and-release message is equally important. The report advises avoiding unnecessary stress on trout if water temperatures exceed 70°F, and points to barbless hooks as one simple way to make release easier and faster. In practical terms, late-summer trout fishing is less about fishing every possible hour and more about fishing the cool hours well.
The late-summer Upper Kern approach: arrive early, fish the cooler window, handle trout gently, and step away once the water becomes too warm for responsible catch-and-release fishing.
The Upper Kern is described as clear and notably quiet during the week in this report. For anglers who can get away on a weekday, that means more room to slow down, move carefully, and approach each run with purpose rather than competing for water.
What to Fish When Trout Are Looking Small
Late-summer trout are not always keyed in on big, flashy meals. The fly selection discussed in the video leans toward smaller mayfly and Baetis-style nymphs that more closely resemble what is present in the stream. Pheasant Tails, soft-hackle Pheasant Tails, and Psycho Mays are all named, along with smaller, brighter attractor patterns for anglers who want a little added visibility without moving up to oversized flies.
Dano’s shop recommendations add a useful reminder: sometimes the right move is not to abandon a dependable pattern, but to change it up with a newer or less familiar fly. The video mentions a Wrecker, a purple Moorish Spark, and a size 14 Tungsten Nightmare as patterns that had been receiving attention, while the Duracell was temporarily out of stock.
Situation reported in the video | Suggested approach or fly choice |
Clear Upper Kern water | Smaller mayfly and Baetis-style nymphs |
Trout not focused on oversized flies | Keep attractor patterns in smaller sizes |
Early morning or evening surface activity | Look for caddis and fish a dry-fly presentation |
Dry-dropper fishing | Use a Fuzzy Wuzzy or hopper-style indicator with a nymph below |
Trying something different | Consider the Wrecker, purple Moorish Spark, or size 14 Tungsten Nightmare |
Dry-fly anglers still have opportunities, especially early and late. The report notes that caddis activity can appear in the morning and evening, making those low-light windows the time to look for fish willing to rise. Along with a traditional Fuzzy Wuzzy-and-nymph setup, smaller rubber-legged and yellow Stimulators are mentioned. The Scaddis is another dry option for caddis activity.
There is also a small piece of gear advice that solves a very practical problem: the Cling Mag Grab rod rack. The rack holds a rod at the vest and frees both hands for changing flies or handling the little tasks that otherwise become awkward while standing in moving water. It is the kind of accessory that does not catch fish for you, but can make a long morning on the river run more smoothly.
Before heading upriver, stop by Kern River Fly Shop for the current local picture and a fly selection suited to the water. You can also shop flies and gear online before your visit, so you are ready for the morning hatch instead of trying to make do with whatever happens to be left in your box.
Lower Kern Bass Fishing: The Season Starts to Turn On
While Upper Kern anglers are watching temperature and choosing their hours carefully, the Lower Kern moves toward one of its most interesting seasons. The report identifies the period from late summer through roughly November as the time to explore the lower river for smallmouth, largemouth, spotted bass, and other bass species. It also notes crappie, bluegill, and catfish in the fishery, with trout generally becoming the focus there during winter.
The water does not need to look complicated. Some of the most promising holding water sits beside faster current: small eddy lines, slow pockets, and edges where the water is not moving as quickly. This is familiar logic for any river angler. Find the current break, imagine where a fish can hold without burning energy, and make a presentation that enters that zone naturally.
The video shows two distinct ways to work those areas. A small popper is used to check whether bass are willing to eat on the surface. When it is time to get deeper, a sinking leader and flashy Kreelex are used to work through the water column. The report also demonstrates a backhanded cast as a practical solution when trees restrict the normal backcast.
Lower Kern water or setup | How it fits the late-summer approach |
Eddies and slow seams beside faster water | Look for smallmouth, largemouth, and other bass species holding out of the strongest current |
Small popper | Test whether fish are willing to eat on the surface |
Sinking leader with a flashy Kreelex | Work a fly lower in the water when surface fishing is not producing |
Backhanded cast | Create a viable casting lane when trees are tight behind you |
For someone who has spent the summer chasing trout, the Lower Kern offers a welcome shift in pace. You still need to read current and make accurate casts, but poppers, streamers, and bass-oriented water create a different puzzle. That variety is one of the overlooked strengths of the Kern River system: the choice is not between fishing and not fishing; it is often between two very different kinds of fishing.
If you want a faster learning curve, Kern River Fly Shop offers guided trips on the Lower Kern, including walk-wade and float options. It is a practical way to learn where bass sit, how to work streamers and poppers, and how to move through this section of the river with confidence. For a stronger foundation in casting, rigging, and reading water, consider the shop’s fly fishing school and clinics.
Late summer does not require a single answer on the Kern. It rewards anglers who match the plan to the hour, the water, and the species. Spend the first light of the day with smaller flies on the Upper Kern. Let the warmer hours steer you toward the bass possibilities of the Lower Kern. That flexibility is what makes Kernville such a special basecamp for California fly fishing.
