heavy rain today at union, yeah it was rough. caught no fish but saw some real big ones swimming around. couldn’t even get my line in the water with all the wind and storms. better luck next time, I guess. still loved being out there.

cloudy day out at union reservoir, caught a couple of small pike, nothing huge tho. used my old baitcaster with some live minnows. wind picked up a bit making it tough but still had a blast. can't wait to try a different spot next time.
