Early spring time creek catfish

At what water temperature would you say that the catfish like to move up in the creeks? My favorite spot hasn't been holding any, and generally do pretty well here, the last few weeks, but with warming temperatures I would expect them to start moving up. Just didn't know if there was a general water temperature range that causes the cats to move into the creeks or not

It's my understanding that a lot of creeks hold a certain population of catfish (mostly channels) year round. I know that I have caught small channels in creeks at all different times of the year. Maybe they just feed more actively during certain times?

They moved up a while back when we got our big rains. They made their way WAYYY up the creeks in the current.
