We present Australia Telescope Compact Array mosaic H i imaging of the Local Group dwarf irregular galaxy WLM .
We find an integrated flux of 149 Jy km s ^ { -1 } and a total H i mass of ( 3.2 \pm 0.3 ) \times 10 ^ { 7 } M _ { \sun } .
The major axis of the H i is aligned with the stellar component of the galaxy .
The overall H i distribution is relatively smooth at our resolution and has a double peaked central core .
One of these peaks is aligned with a region found to have extinction that is internal to WLM and we take this as possible evidence of a large molecular gas complex in the southern half of the galaxy .
The other H i peak is in close proximity to the brightest H ii regions .
WLM ’ s overall velocity field is consistent with rigid body rotation .
A rotation curve is derived , and we find a total dynamical mass of ( 3.00 \pm 0.80 ) \times 10 ^ { 8 } M _ { \sun } .
We also performed a wide field search , 38 \arcmin in radius , for H i companions or evidence of recent interactions ( e.g. , tidal tails ) , and found no detections to an H i mass limit of M _ { HI } > 8.4 \times 10 ^ { 5 } M _ { \sun } .
