This gauge reports level but no water temperature, so depth calls stay open. Read the windows and the pressure trend instead.

Questions people ask about Diamond Lake

Answered from the same readings as the rest of this page. Where we have no basis for an answer, there is no entry — spot-by-spot local knowledge is not something we can claim for Diamond Lake.

Is it worth fishing Diamond Lake today?
7 out of 10 — biting. Worth a cast. The strongest stretch is 12:24 AM–2:24 AM. That number is worked out fresh each morning from the solunar windows, the pressure trend, the water level.
What time should you fish Diamond Lake?
Today's major windows run 12:24 AM–2:24 AM and 12:48 PM–2:48 PM, with minor windows at 7:44 AM–8:44 AM and 6:40 PM–7:40 PM. Sunrise is 7:01 AM and sunset 6:56 PM. A major landing on first or last light is the stretch worth setting an alarm for.
What is the water temperature at Diamond Lake?
No gauge on Diamond Lake measures it, so this is an estimate: roughly 60.8°F, worked out from the 7-day mean of air temperature at NOAA weather station KRBG (Roseburg Regional Airport). Checked against the lakes that do have a thermometer, that method lands within about 4.5°F of the real reading and was off by 8.3°F at worst. Treat it as a ballpark, not a measurement — and note the bite index above ignores it entirely, because an error that size would move the verdict as often as it would fix it.
What is the water level at Diamond Lake right now?
5184.19 ft, read at 5:30 AM from USGS station 14312450. Over 24 hours it is down 0.00 ft.
Are water levels rising or falling at Diamond Lake?
Holding steady. The lake is unchanged 0.00 ft in 24 hours and up 0.02 ft over the week. Over the last 8 days it has held between 5184.15 and 5184.23 ft. Every figure here is a difference between two gauge readings, not a forecast — what the level does next depends on rain and on what the dam releases.
Can you eat the fish you catch in Diamond Lake?
That is a health question, and it is answered officially rather than by us. Oregon Health Authority publishes the fish consumption advisory covering these waters, where Oregon limits bass statewide over mercury, with further advisories on the Willamette and Columbia. Read it before you keep a meal — we give no eating advice.
Do you need a licence to fish Diamond Lake?
Yes. A Oregon fishing license covers this water, required from age 12. ODFW sets the rules and is the one that counts.
What size fish can you keep in Oregon?
It depends on the species, and several have slot limits rather than a simple minimum. Open to harvest today: trout (rainbow, redband and other stream trout), kokanee, bass (largemouth and smallmouth), bluegill, catfish, crappie, sunfish, walleye, yellow perch and whitefish. Seasons here change mid-year by agency order, so the status is re-checked every morning.
