Help around Austin please

I'm looking at fishing on the river in the morning. TPW shows a ramp of 973 and Hwy 71. All I see under the bridge is a makeshift gravel ramp. Have any of you used this or is there a better option?

Look on Google Earth at Webberville, Water st and Old Country Lane. Probably light rigs only but vehicles parked there with empty boat trailers, ramp visible.
