Lake Houston/ east San Jac river

Does anyone fish lake Houston or the east San jacinto river for sandies? I just make to Humble from Dallas and am trying to find where the sandies spawn in the river. I am bank bound, I tried to explore some this and last weekend and all I found was private property on both Caney Creek and San Jac.

i have heard the white bass are good under the bridge at cypresswood google search cypresswood golf club and its the river right there i have seen alot of cars/trucks parked there
