I plan on going in the morning for the first time and want get some info. Not asking for peoples spots, i just want to know if all ramps are usable, water temp, any areas to go slow in, sand bars, etc...

Kickapoo, beacon bay are two best ramps to use, honestly don't know water temp as never even turn on depthfinder... go slow all in Kickapoo. It's now a very shallow ditch instead a main creek haha, It's still as wide just way shallow with slot of wood in it.

How about lake Conroe? Are ramps usable?

I know stowaway is useable but that's all I know. I never fish conroe sorry

Launched at Stowaway a week ago, usable, a bit tight going out to the channel, take your time and it is all good. I did not power load, but got the boat loaded with no problem.
