We completed a bathymetric survey at Priest Rapids Dam, which included coordinating and acquiring survey control to allow for maximum coverage, while avoiding obstructions or signal loss.  

In addition, the vertical component was verified by check shots onto existing benchmarks to ensure compatibility with previous surveys.  The horizontal component was collected and converted to NAD27 for final deliverable.

GPS was utilized for the majority of the bathymetric work and the survey accuracy was +/- .5 feet in both directions.
