@mattybfat is in point. Trails in both parks are in great condition.
Deer Park has a fee trees down scattered throughout the park. The heavy overgrown areas are not too bad right now as the really bad area(s) were addressed last weekend. That being said, I'm sure there is a sticker here and there.
Stephens is in good shape as well. There was a TM session there today focusing on the Little Grunt trail that cuts the corner of Kinney Rd and Waterloo Valley Rd as well as 1/2 of the Holy Grail from Waterloo Valley Rd to the lower railbed section heading towards Continental Drive. A consorted effort was made to attack the heavy burning bush growth. Not completed 100%, but a ton better.
Get out there and have fun!!!
