During March, drought conditions intensified across South Texas. Most locations along Interstate 37, west to the Rio Grande River experienced All of South Texas experienced less than 50% of normal rainfall for the month of March, with much of this area less than 15% normal. A few areas saw less than 5% normal rainfall for the month.  Northeast of Interstate 37, beneficial rainfall did fall, with many areas seeing between 75 and 100% normal rainfall.  But this rainfall was insufficient to make a dent in the long term drought index,
By the end of March, exceptional drought conditions continued across Goliad, Victoria, Refugio, Calhoun, and Aransas counties. Extreme drought conditions continued across Bee, San Patricio, Nueces, and Live Oak counties, and expanded through McMullen, La Salle, Kleberg, Jim Wells, Duval, and northeast Webb counties. Severe drought conditions were observed across southwest Webb County. (per the U.S. Drought Monitor: http://www.drought.unl.edu/dm/monitor.html)
The primary impacts of the drought through March continued to be agricultural and fire related.  However rainfall received in the latter half of March did allow some farmers to plant, but the soil moisture was thin.  According to media reports, ranchers in Texas have lost over 800 million dollars since the summer of 2008 due to the drought.  Effects on cattle production, range and pastureland in South Texas may take years to recover.  Periods of critical fire danger occurred through the month with sporadic wildfires.
In addition, reservoir levels continued a gradual fall. Choke Canyon Reservoir was near 78% capacity and Lake Corpus Christi near 57% capacity by the end of the month. Except for the Rio Grande, river and creeks levels throughout South Texas remained below normal.
