A couple of places I've had luck over the years are the Brazos and Navasota River banks below the Hwy 105 bridges. My buddy and I would fish that area, north & south of the highway, pretty often in an old flat bottom boat with a trolling motor. We would stop on the little islands and places where there was a noticeable runoff after a rain. I did't have as good an eye as he did but managed to find many good arrow points and scrapers over the years. We donated some of our better finds, spear points and scrapers, to the Washington on the Brazos Museum.
We probably had luck finding something 25% of the time we were actually looking but like most things nothing was a guarantee. We were mostly hoping to catch a big cat and just enjoying our time out there.
Some of the points and scrapers I found over the years in that area.
