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?
8 out of 10 — on fire. Drop everything. Go. The strongest stretch is 12:46 AM–2:46 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 12:46 AM–2:46 AM and 1:11 PM–3:11 PM, with minor windows at 6:48 AM–7:48 AM and 8:19 PM–9:19 PM. Sunrise is 6:12 AM and sunset 8:13 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 water temperature. US reservoir gauges report height, not temperature — so rather than estimate it, this page leaves it out and leans on the windows and the pressure trend instead.
What is the water level at Diamond Lake right now?
5183.97 ft, read at 12:30 AM from USGS station 14312450. Over 24 hours it is down 0.00 ft.
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.

OHA fish consumption advisory

What size fish can you keep in OR?
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.
