I looked on Google Earth to see good directions from Katy to Chocolate Bayou Boat Ramp off of FM 2004 over bridge going South. Here is the GPS Location: 29*12'41.76"N 95*12'31.70"W, Elevation is 3ft for you Denver Fly Fisherman!! It's a 1.5 hour drive from Katy area. Come the best way thru Houston an get on Hwy 288S and exit on Hwy 6 to Alvin TX, to second Hwy 35 (Bypass) turn right at 1st National Bank on corner go around Alvin. Go about six miles passed Kroger's. Take a left on to FM 2917 go all the way to FM-2004.. Watch you speed, state trooper work these areas--Gas Station on your right which is the last place to buy gas, food and drinks... Turn right on to FM-2004 from gas station and go apprx 3.5 miles. Go over the bridge exit right to boat ramp which is under the bridge. The west side of boat ramp is where most yak's launching is done. I will go and look at the water to see how much fresh is in the bay and bayou...Remember you must have a freshwater license west of 2004 Bridge... any questions call me 713-816-0884. See at meeting!!
