48.7	Flood of record - Septemeber 24, 1967 - remnants of Hurricane Beulah (138,000 cfs)
43.5	Massive life threatening flooding occurs, and severely damages residential areas below Bluntzer to Calallen. Major flooding of the flood plain below Lake Corpus Christi to below Bluntzer, floods roads and bridges near the river. Livestock are cut off and potentially drowned. Just below the dam, water is over the Highway 359 bridge around the right end
29.34	Major lowland flooding occurs, causing widespread evacuations downstream above Calallen. The west bank residents below Bluntzer may be cut off for several weeks
28	Major lowland flooding occurs, causing widespread evacuations downstream above Calallen. The west bank residents below Bluntzer may be cut off for 4 to 6 weeks
27	Flow moves into a secondary channel, 700 feet left of main channel, resulting in two channels. These channels merge at 43.5 feet
26	Moderate lowland flooding occurs. Many homes downstream between Bluntzer and Calallan become flooded, with residents possibly cut off for weeks
25	Minor lowland flooding occurs. Flow escapes secondary banks of the main channel. There is widespread flooding of the flood plain downstream, between Bluntzer and Calallen, cutting off many homes and residential areas for days and possibly weeks
20	Overbank conditions continue. Residents downstream near Bluntzer may become isolated
17	Many homes in flood prone areas downstream above Calallen are cut off and surrounded by water
16	The river reaches bankfull stage. Short peak releases will flood homes near Calallen
13	Sustained flow will isolate homes downstream near Calallen
12	Flow cuts off the lowest homes downstream above Calallen
