San Bernard River Height and Flow Data
for May 2006We have not found a source for
historical height and flow data on this area of the San Bernard.
Eileen began collecting the Sweeny readings each day from the web
starting in fall 2002. Currently, Bob Bailey, who lives in Lazy
Oaks, and Roby Warwick, of Houston, have been collecting the river
height and flow data from the web each day for us. Bob Bailey has
also been collection periodic water temperature data. Below is the
information for May 2006, as well as

Definition of Action
Stage* |
- Stage at which some person or agency
needs to pay attention to the hydrologic situation and
perform a function.
- There can be no flooding at this
stage.
- Action stages are not mentioned in
issued products.
- Forecasts for action stages are given
directly to the action agency.
|
|
Definition of Flood
Stages |
- The term Minor Flooding is
used to indicate minimal or no property damage. However,
some public inconvenience is possible.
- The term Moderate Flooding
is used to indicate the inundation of secondary roads.
Transfer to higher elevation may be necessary to save
property. Some evacuation may be required.
- The term Major Flooding
is used to indicate extensive inundation and property
damage, usually characterized by the evacuation of
people and livestock, and the closure of both primary
and secondary roads.

| Impacts
(as stated by NOAA) |
| 25.0 |
At levels near
25 feet water is over the top of the dock at the Phillips
Terminal near Sweeny with all vessel traffic stopped.
Widespread inundation of the left flood plain occurs.
|
| 17.0 |
At levels near
17 feet water is over the mid level walkway at the Phillips
Terminal near Sweeny. Tractors can not push barges upstream
and are unable to dock. Water begins spilling into the left
flood plain. |

At levels near
16 feet water is over the mid level walkway and tugs can not
push barges upstream and are unable to dock. |
