Partially-complete in-stream structure for mounting water quality sondes

Continuous water-quality data are collected in streams like War Branch (pictured) using sondes, which are mounted to submerged in-stream structures like the one pictured here. These structures are constructed out of metal u-channel posts, and the data cables which connect to the sondes are protected by PVC pipes.

When completed, a water quality sonde will be attached to the lead cables and the posts protruding above the water line will be cut so that the entire structure is submerged.

NWIS data for this site can be found here.
