Does anyone fish Texoma for post-spawners? What portions of the lake since this one is a biggy? Any suggestions?

yes, but you better have prepared brush piles....there is little or zero cover left in the lake. we have some brush in the walnut creek area that produces pretty good when they're on their summer patter. otherwise i would try the willis bridge columns north of whitesboro on hwy 377.

So I guess that most of the crappies are either hugging the first drop or suspend a great deal of the time? Are there any good creek channels toward the west side of the lake?

i'm sure that's probably true, but we've never caught them without some type of structure involved...usually in 15' to 25'. south end of the bridge (tx side). some of the water under the bridge is 45' to 50', near the river channel.
