What water temps are you looking for to indicate the start of the spawn for largemouth?

What water temps are you looking for before the white bass start to move from the main lake and into the rivers?

Around 60 but have seen it go both ways

I've seen bass spawn in temps as low as 55. The texts books will tell you 62 which is probably a good all around average. If you wait until 62 though many fish will have spawned. Bass are going to start moving towards spawning locations essentially anytime. The first warm three day southern blow in your area should have mianlake points on the north side of lakes stacked with big pre-spawn females. The time is now!

57-58 is when I start looking but even then several variables have to be in play like how fast did the temp get there and the stability of weather surrounding that temp. But in the end not all fish act the same all the time so you have to keep experimenting. It doesn't take long to pick a textbook spawning pocket and go look or fish around and see. Fish will tell you what they are doing by what you get bit on and how they act.

I start focusing on spawning flats and shallows when temp reaches 55-58

Unless the water temps drop drastically say from 58 to low to mid 40's due to an Arctic front, I do not think water temps are all that important. IMO, the combination of the water temps "warming up" and the days getting longer and nights getting shorter is what triggers the spawn. If I had to put a number on it, I would say when the water goes from mid 50's to high 50's to low 60's that is a key time for the fish to start moving up.

Another key element is stability of the temps and also the stability of the water.

It varies from lake to lake, but usually around 60 degrees for largemouth.

Can't comment on white bass as I don't fish for them.

White bass tend to really get moving up the creeks at around 55. Especially right after a warm rain.

When I fished for them, we assumed water temps 52-54 to be the magic number to get it going.

It's a combination of photoperiod and temperature that gets them going; but they'll go ahead and get started if one is just right and the other is off (example, the length of day is right but the water is only 56). I'll start looking in the spawning areas when the water stays in the mid to upper 50's for several days. They might not be there yet but they'll be on their way, follow the migration paths outwards until you locate them.

White bass seem to start running at about 55 in my experience.

Time is now especially if you can find grass to hold heat in or near spawning areas for staging fish. No grass fish creeks, feeder creeks and points or drains leading in. Have site fished bedding fish in the grass in Jan in 55-60 degree water when the main lake was still upper 40s to low 50s after a week of really warm weather. Fished a lake with grass last weekend and we caught 15 up to 8lbs no deeper than 6 ft and most were 1-2 ft in 49 degree water on Sat. The back of the creek is full of grass and the warm days warms the area faster and the grass holds the heat better plus gives cover. Otherwise I look for 58-65 for them to really get on beds. And the first warm rain that gets a current moving in the creeks will get whites going.

Photo period is sometimes more important.

My experience is it depends on the lake... couple lakes I�m already catching them in shallow water in spawning areas with full bellies and the water temps were high 40�s low 50�s in the afternoon. Other lake I typically fish it seems like the water has to be bath water to find the bigger girls up shallow... many buck bass will already be on the areas though.

Also any 3-4 day warming trend is a good time to get a line wet no matter what the water temp is if it�s this time of year.

It really depends on what the water temp was 4-5 days ago. Bass will push shallow on warming trends. I've even seen males on Rayburn on beds already. Temps plays a role but it's more about relative temp to what it was a week ago. I've caught some big fish in 58 degree water on beds if conditions are right. Rayburn is low 50's btw
