These move by emergency order, sometimes mid-week, so this page prints no number and links to the source instead. The score does not weigh them either: it ranks fish passage, the migration lane, river state, elbow room and crowding, all of which are measurements rather than regulations. Always check ADF&G emergency orders the morning you go.
▸Flossing rig and techniquethe Kenai flip
Sockeye push upstream with their mouths open, 6 to 10 feet off the bank. You are not tempting them, you are putting a leader where the mouth is.
▸Which bank: left, right and whyUSGS convention
The convention. River-left and river-right are defined looking downstream, standard USGS usage. The Kenai flows west to Cook Inlet, so river-left is the south bank and river-right is the north bank. ADF&G closure documents use north and south, so every card here shows both.
The daily split is real data, and this page does not carry it.ADF&G now publishes a per-bank breakdown in the Notes column of the Fish Counts page, and spells out the mapping on the 1 July row: left bank is historically south, right bank is historically north. Daymingo's feed does not carry that column, and it is this season's daily data, so freezing a copy of it into this page would be the exact failure the rest of the report is built to avoid. The long-run means are published and durable: the Kenai has averaged about 49 south to 51 north across 1979 to 2014, and the Kasilof about 31 south to 69 north across 2007 to 2015.
What the sonar itself tells you about the banks. The RM 19 site is not one counter, it is two, one on each bank, each with its own transducer. The interesting part is that they are not the same size. ADF&G ensonifies about 98 feet out from the north bank but only about 66 feet from the south. They do not need as much reach on the south side because the bed drops away more steeply there, so the deep water and the travel lane both sit closer in. On the north bank the bottom shelves out gradually, which is why they have to look nearly half again as far to catch the same fish.
What that means for where you stand.On the south bank the fish lane is close, and ADF&G measured over 90 percent of south bank fish inside 16 feet of shore. On the north bank you are working a shallower shelf and the lane sits further out, so you need more reach and a slightly heavier presentation to hold bottom in the same current. Both banks carry fish. The south bank simply brings them to your feet sooner. One day's split is a weak signal on its own, which is why this sits down here rather than at the top: go where the fish and the access are, then pick your bank.
The rule that saves a closed bank. A seasonal bank closure closes the bank, not the water. In any closed stretch you may still fish while standing in the river at least 10 feet out from the shoreline, or from a boat more than 10 feet off that is not tied to shore or to riparian habitat. That is why closed spots still appear in the list here, flagged, rather than being hidden.
Bends.On a meander the inside is a shallow point bar with slow water, the outside a deep cut bank with fast water. The energy argument says migrating fish favour the slower inside line, and that matches how the good spots fish. ⚠ No study measures this directly for Kenai sockeye, so treat it as sound reasoning rather than documented fact.
When it rises. A flooding river pushes the soft-water margin up the bank, so the lane moves toward you and often gets easier to reach, but it dirties and wading gets dangerous. Favour confluences and defined holes, which keep their shape; avoid wide tidal flats, which blow out first. The cards flag which is which, and the score shifts weight toward high-water spots automatically when the river is up.
▸How the model works and how to regenerate itmethod
Speed.Two ADF&G travel times pin the Kenai. Mouth to RM 19 is 24 to 36 hours, so the tidal lower river runs about 15 mi/day. Mouth to the Russian weir is 7 to 10 days over roughly 78 miles, which only reconciles if water above the sonar is slower. Solving both gives about 9 mi/day from Soldotna to Skilak. Fraser radio telemetry puts in-river sockeye at 25 to 36 km/day, 15 to 22 mi/day, so the lower figure sits inside the published range and the upper is conservative.
⚠ The Kasilof is deliberately NOT modelled the same way.Earlier versions applied a 12 to 36 hour mouth-to-sonar transit. ADF&G's own personal use page says plainly: to date, the Department has not done any research to determine how long it takes a salmon to travel from the mouth upstream to the Sterling Highway bridge. Kasilof numbers now come straight off its RM 7.8 counter with no transit model, and the density heat map is not painted onto it.
What the day picker does.Picking a future day advances the migration model by that many days and swaps in that day's forecast, its tides and its light. Fish counts for a future day cannot be measured, so they are this calendar date's median across the complete seasons, scaled by how the last three real days actually ran against their own medians. That is why a future tab can change the winning spot: the cohorts move upriver.
What the score weighs. Fish passage 40%, how tightly the lane hugs the bank 30%, how well the spot fishes at the current river state 14%, elbow room 7%, crowding 9%. There is no bag limit term. The standalone build weighted the limit at 10 per cent, which meant a regulation changed which spot the page recommended with nothing on screen saying so; that 10 per cent went to fish passage and the lane, the two terms that are measurements. The river-state term only bites when the river is rising; otherwise it goes neutral so it cannot quietly skew the ranking on a calm day. A spot inside a seasonal bank closure scores below zero and cannot win anything.
Flow cuts both ways. Published work finds high discharge suppresses migration rate rather than speeding it, while the lowest flows stop river entry altogether, and the discharge signal shows at a counter 7 to 12 days later. A rise is a genuine entry cue and simultaneously a brake on transit.
Temperature. Impairment sits around 18 to 19 C. Warm for this river matters for handling, but it is not slowing the run. An earlier version implied it was, and an earlier version also hand-typed the number, which is how it went stale. It now comes off the USGS gauge through the feed.
Drop-out. Passage upstream is discounted by a retention curve calibrated against the Russian weir taking roughly 16,000 late-run fish for every 994,000 past the Kenai sonar. Without the curve the model claimed 171,000 fish a day were crossing River Mile 76 and ranked the Russian campground the best bank spot in the drainage.
The map. Geometry is an OpenStreetMap centerline, simplified and split into 90 segments each tagged with its own river mile, which is what lets the heat colour ride the actual channel. The scale bar is derived from the projection and checked against six known town-to-town distances, all within 0.3 percent.
Regenerating this daily. Everything time-derived comes from daymingo.com's own feed, which the site refreshes every day: the daily counts for all three rivers, the Soldotna forecast, the Nikiski tide table, sun, moon, NWS alerts, and the USGS 15266300 gauge at Soldotna. The only things not in the feed are the twenty season history, the projection ratio table and the odds table, all three rebuilt from the same ADF&G export (countLocationID 40, 41, 13; speciesID 420 sockeye, 421 Russian early, 422 Russian late), and the OSM map geometry, which only changes when a river moves. Swap the feed and the whole page recomputes, heat map included, because markers are placed by river mile rather than hand-positioned.
About the Kenai River fishing report
This is a daily, weather-first sockeye report for the three rivers most bank anglers on the Kenai Peninsula actually fish: the Kenai, counted at the ADF&G sonar at River Mile 19, the Kasilof, counted at its own sonar at River Mile 7.8, and the Russian, counted at the weir above the confluence. Pick a river in the ribbon at the top and the map, the stretch cards, the access list and the section summaries all follow it. Sections built on Kenai sonar measurements say so in their own summary rather than showing you a Kenai number under another river's name.
The survey underneath it is 31 public bank access points across 9 stretches, each with its river mile, its bank, how far the public bank runs, what the water does there, where to stand, what facilities and fees the managing agency publishes, and whether it sits inside a seasonal bank closure. The managers are the City of Soldotna, the City of Kenai, Alaska State Parks, the US Forest Service and the Kenai National Wildlife Refuge, and the report links to each authority rather than paraphrasing it.
Seasonality, in one paragraph.Sockeye are the summer run and the reason most people are standing in the river: the Kenai carries an early run and a much larger late run, the Kasilof runs on its own schedule with a hatchery component bound for Crooked Creek, and the Russian has an early run and a late run through the same weir. Pinks are a tidewater and lower river fish on the Kenai's even-year lineage. Coho, the silvers, arrive behind the sockeye and are a middle river fishery from Soldotna up to Sterling. Which of those is worth driving for on any given day is what the counts, the tides and the light bar above are for.
Regulations are not printed here, ever.Bag and size limits on these rivers are set in season by ADF&G emergency order and can change more than once a week, so this page links to the source instead of caching a number that goes wrong within days. Read the Southcentral sport fishing regulations, the emergency orders and news releases and, for dipnetting, the Cook Inlet personal use pages the morning you go.
Fish counts, weather, tides, sun, moon and NWS alerts come from daymingo.com, the feed the site refreshes daily, which pulls ADF&G Fish Counts (countLocationID 40 Kenai, 41 Kasilof, 13 Russian). Twenty seasons of history from the same export. Flow and water temperature from USGS 15266300 at Soldotna. Map geometry OpenStreetMap. River miles are ADF&G's, cross-checked against an OSM centerline rebuild that reproduces every published landmark within half a mile. Check ADF&G emergency orders before you fish.
