Who knows Lake Roosevelt well?

[Rick]

Spent last week fishing Roosevelt. Came across a ton of suspended fish on the sonar. They were suspended at 115-120’ in 150ish feet of water.  My guess is whitefish but it is just a guess.

Surface temp was 72-76 degrees

Where were you on the lake?  Was this throughout the day or just a certain time frame? I've found the rainbows suspended like that a time or two, but usually only on bright days in the afternoon. Don't think it was whitefish. Did you put lures down that deep to see if there were any takers?  I've taken trout that deep, usually on a flashy pop gear with a baited wedding ring behind it

My guess is Kokanee depending on the area but I’ve also trolled that deep through rainbows. Don’t count burbot out

Whitefish... I see them suspended like that too. A walleye tournament fisherman was staying here at the Lodge and saw all the deep suspended fish....so , he put down an underwater camera to see what they were...whitefish..big schools of them. These are the Lake Superior whitefish..not the Rocky Mountain variety.

I've jigged those depths and caught walleye and trout. I've never got a whitefish here

I marked a couple waypoints over the school.  The school was about 1/4 mile long. We ran Kokanee and trout gear on the DR multiple times and no takers. I also ran some walleye plugs and double whammys on the DR with no takers.

I didn’t think burbot because I thought they were mostly bottom dwellers.

Not meaning to thread jack. While fishing Lake Pend Oreille, I talked to a local that seemed rather knowledgeable on the lake. He mentioned a study done by the state, conclusion of the study was that whitefish made up the largest bio-mass in the lake. We sure marked a bunch, always in large schools.

Go on you tube and search whitefish Washington state...WDFW even did a video of catching whitefish in Banks Lake...Lake Superior variety.I've caught them while jigging for walleye in Halls Creek...Some go over 7 pounds.
