Ever wondered about how groundwater observation wells are drilled? This photo provides a behind-the-scenes look as USGS drilled a groundwater well in California last month. This photo looks down over a mud tank and shakers, which are part of drilling operations. The drillers pump clean mud from the tank down the hole as they drill; this mud plays an important role in

Speed Rail and Kee Lite are two common manufacturers of aluminum structural pipe fittings, a popular material in which to construct index-velocity meter mounts.

The AVM measures the average water velocity along the acoustic path (VP, figure 1); then computes the "line velocity," the velocity component parallel with the average downstream flow line.

Old custom made Kentucky-style mount on several different boats from Kentucky and Illinois deploying both Broadband (BB) and Rio Grande ADCPs. A pole can be fixed to the mount for deploying a GPS antenna located on top of the ADCP. The Kentucky-style mount constructed of Speed Rail is recommended for Rio Grande Workhorse, RiverPro, RioPro, and Sontek M9.
