From the readings you gave and the date of your post you were probably reading the Butte la Rose gage on the Atchafalaya River.
That is what most people on the west side of the Basin use. It will need to get to about 11 ft. before fishing starts to get any good. You might try before that but I don't think you will have as much success as if you were to wait.
Here is a link to the Butte la Rose gage.http://water.weather.gov/ahps2/hydrograph.php?wfo=lix&gage=blrl1&view=1
The Lake Pelba gage at I=10 is here.http://waterdata.usgs.gov/la/nwis/uv/?site_no=302020091435700&PARAmeter_cd=00065
For almost all real time gages look here.http://waterdata.usgs.gov/LA/nwis/current/?type=flow
You need to copy and paste the entire link (for some reason LA Sportsman forum won't make the entire link a hyperlink) into the address bar on you web browser.
