Distribution Overview
Water hickory is found in low, wet woods from Texas east to Florida and north to southern Illinois and Virginia (distribution map). Individuals of this species can tolerate both a wetter site and a wider range of soil moisture levels than any other hickory, surviving on poorly drained, tight textured soils that are flooded in winter and parched in summer. It is a major component of two forest cover types: Sugarberry-American Elm-Green Ash and Overcup Oak-Water Hickory. In north Louisiana, water hickory is found in association with C. ovata and C. cordiformis on Guyton soils. The position of the species is distinct, however, with water hickory occupiing the lowest, wettest sites

Slight twist/warp
Slight surface checking
Slight end splitting

End checks, hairline splits, and warping may also occur

Ease of Drying

Fairly high risk of shrinkage
Dries rapidly with little or no degrade


Kiln Drying Rate
Naturally dries slowly


Tree Size
Trunk diameter is 100-150 cm
Tree height is 30-40 m
Bole length is 20-30 m
Trunk diameter is 150-200 cm
Trunk diameter is 200-250 cm


Tallest of all the hickories

Comments
'bird pecks' leave residue

Deposits - Magnesium carbonate deposits are present in the wood, and 'Bird pecks' leave residue that crystallizes.

Deposits in the wood

This species is a True pecan, and can be separated from the True hickories by weight, and by the narrow bands of parenchyma, which appear between the rays and between the large earlywood pores. (In hickory the band occurs after the first row of earlywood pores.)

Blunting Effect
Severe effect
Medium effect


Cutting Resistance
Easy to saw
Fairly Difficult to Very Difficult to saw


Gluing
Use special attention for best results
Satisfactory gluing properties

Carefully controlled conditions are required

Moulding
Requires special attention.

A reduced cutting angle of 20 degrees is suggested for best results

Movement in Service
Stable
Small

Small movement after manufacture

Nailing
Pre-boring recommended


Planing
Special attention required

Material with irregular grain requires a reduction in cutting angle of 20 degrees

Resistance to Impregnation
Wood is moderately resistant to treatment


Response to Hand Tools
Fairly Difficult to Difficult to Work


Sanding
Good sanding qualities


Steam Bending
Excellent


Polishing
Fair to Good Results
Good results


Staining
Stains well


Strength Properties
Heavy
Compression strength (parallel to grain) = high
Bending strength (MOR) = very high

Bending strength in the air-dry condition (about 12 percent moisture content) is very high. Compression strength parallel to grain, or maximum crushing strength, is also very high - higher than in Teak or Hard maple. It is a very heavy wood
