WINNIE SERIES


The Winnie series consists of very deep, poorly drained, slowly permeable soils that formed in loamy fluviomarine sediments of late Pleistocene age. These nearly level soils are on dune slacks on strand plains. Slope ranges from 0 to 1 percent, but are mostly less than 0.5 percent. Mean annual temperature is about 20.5 degrees C (68.5 degrees F), and mean annual precipitation is about 1397 mm (55 in).

GEOGRAPHIC SETTING:
Parent material: loamy fluviomarine sediments derived from the Beaumont Formation of Pleistocene age
Landscape: Coastal plain
Landform: strand plains
Microfeature: dune slacks
Slope: 0 to 1 percent
Mean annual air temperature range: 20 to 22.2 degrees C (68 to 72 degrees F)
Mean annual precipitation range: 1219 to 1575 mm (48 to 62 in)
Precipitation Pattern: Rainfall is fairly uniform throughout the year with slight peaks in the Fall and Spring months.
Frost-free period: 270 to 300 days
Elevation: 3 to 30.5 m (10 to 100 ft)

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Anahuac, Leton, Levac, Meaton, Spindletop, and the Stowell series.
Anahuac soils: fine family; on relic bars and levees
Leton soils: relic fluvial channels
Levac soils: fine family; are truncated mounds
Meaton soils: fine-silty family; somewhat poorly drained; on flats
Orcadia soils: coarse-silty over clayey family; on relic bars and levees
Spindletop soils: moderately well drained; on pimple mounds

DRAINAGE AND PERMEABILITY: Winnie soils are poorly drained. Runoff is negligible. Permeability is very slow due to crawfish bioturbation. These soils are rarely flooded for very brief to brief periods. Flooding occurs as a result of storm surge during tropical storms which occurs in areas less than 4.6 m (15 ft) elevation. These soils frequently pond 2 to 8 cm (1 to 3 in) above the soil surface for long periods from January to March; have endosaturation from 22 to 203 cm (9 to 80 in) below the soil surface from January to March.

USE AND VEGETATION: Mainly used for wildlife land or pastureland; typical vegetation includes bluestems, sedges, panicums, paspalums, Carolina jointail, and rushes.

DISTRIBUTION AND EXTENT: Southeast Texas; LRR T; MLRA 150A; minor extent

MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Temple, Texas

SERIES PROPOSED: Chambers County, TX, 2013; the name is for a community in Chambers County, Texas.

REMARKS: These soils were formerly included in the Clodine series. Clodine soils are associated with the Lissie Formation.

Diagnostic horizons and features recognized in this pedon are:
Particle size control section: 57 to 107 cm (22 to 42 in) (Btg1 or Btg2 horizons)

Ochric epipedon: 0 to 17 cm (0 to 7 in). (A horizon)
Cambic horizon: 17 to 57 cm (7 to 17 in). (Bg1 and Bg2 horizons)
Argillic horizon: 57 to 203 cm (17 to 80 in. (Btg1, Btg2, Btg3, Btg4, Btg5 horizons)
Aquic conditions: 0 to 203 cm with a positive reaction to a,a, dipyridyl from January to March in normal years

Additional Comments: Cambic horizon is due to crawfish bioturbation that have mixed surface and subsurface layers.
