Hard Times for Dragonfly Larva?

This area was inundated from the fall / winter of 2013 to sometime in the late-spring / early-summer of 2014.  When this area was inundated this spring (2014), there were lots of adult dragonflies buzzing about.  On several occasions I observed dragonflies laying eggs and white ibis foraging for crayfish in the water found here.

 

Where is the water?

Now, however, the surface water is gone and the truly aquatic organisms apparently have to fend for themselves, or croak and join the detritus community.

 

How’s this for aquatic habitat?

Although I have seen few to no chimneys, I presume that the crayfish that survived the white ibis and feral hog foraging bouts can and probably have excavated burrows down into the still moist subsoil.

Survival in these habitats might be more of a challenge for aquatic dragonfly larva if they require a true water column, and not just moist mud, for a development period that overlaps these summer dry spells.
