In lower Montgomery, upper Harris county we have 4 venomous snakes, only 3 of which you are likely to run across: Southern Copperhead, Western Cottonmouth, Texas Coral snake. Below are photos pointing out the identifying marks.
I often see coral and copperhead snakes sunning themselves on trails along the bayous in the summer.
