Mountain laurel, bluebonnets, water temp?

Some people say when you see certain wildflowers start to bloom its the start of this fishing season. What do yall look for certain water temp/flow etc.?

started about 2 weeks ago, water temp in the 50's, havent seen one flower

i saw some bluebonnets on highway 71 near LaGrange last weekend

When you see a Robin, the whitebass have started their spawning run.
When you see the dogwoods bloom, the crappie have started spawning.
When you see bluebonnets in full bloom, the spawn is just about over.

That's my observation.

I always heard when you see the willows along the creek start to bloom, the whites have moved in

In parts of ETX, i just use a calendar. I know how far up the river they should be on Valentine's and by last weekend of February it's a full on catching fest. Rain/flow has a big effect though.

I watch for all of this to happen, in hopes of hitting the migration at the right time.

I have finally figured that if I wait for any of this to happen, I'm usually too late.

Good luck predicting the sandbass run, they show up when they want to show up. Usually some time between New Years and April they just show up, Ive got picture of limits of nice sandies I caught up a creek on New Year’s Eve, it was 18 degrees outside and we were knocking ice off our rod eyes. they were milting and everything. I’ve also seen years when they don’t show up until late March. Generally in north Texas it peaks around the first or second week of April, but good luck predicting the sandbass run because they just show up when they want to. Usually it gets better when it starts to warm up but you never know. Crappie are a little more predictable, generally early April when water temps get in the 60s.
