History

What this means

Lake Corpus Christi near Mathis is at a record high at 91.43 ft.

No reading on record has been higher: the old record was 48.70 ft, from September 24, 1967. That puts it 3.70 ft above the median of 87.73 ft for mid-October, based on 7 years of readings. A year ago it stood at 77.25 ft (+14.18 ft).

The level has held steady over the past 24 hours. In the last month it has stayed between 91.42 ft and 91.98 ft.

Lakes and reservoirs often sit lower in fall after a summer of evaporation and use, and recover with winter rain and spring snowmelt.

Flood levels and safety

Most flood deaths in the US happen in vehicles. Six inches of fast water can knock an adult off their feet, and a foot or two can float a car. If a road is covered, turn around.

Readings can change quickly after heavy rain upstream, so check again before heading near the water.

What happens at each level

91.43 ft: Right now
48.70 ft: Flood of record - Septemeber 24, 1967 - remnants of Hurricane Beulah (138,000 cfs)
43.50 ft: 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 ft: Major lowland flooding occurs, causing widespread evacuations downstream above Calallen. The west bank residents below Bluntzer may be cut off for several weeks
28.00 ft: 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
27.00 ft: Flow moves into a secondary channel, 700 feet left of main channel, resulting in two channels. These channels merge at 43.5 feet
26.00 ft: Moderate lowland flooding occurs. Many homes downstream between Bluntzer and Calallan become flooded, with residents possibly cut off for weeks
25.00 ft: 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
20.00 ft: Overbank conditions continue. Residents downstream near Bluntzer may become isolated
17.00 ft: Many homes in flood prone areas downstream above Calallen are cut off and surrounded by water
16.00 ft: The river reaches bankfull stage. Short peak releases will flood homes near Calallen
13.00 ft: Sustained flow will isolate homes downstream near Calallen
12.00 ft: Flow cuts off the lowest homes downstream above Calallen
