Problem with Skewed Line Artifacts in DEM Data

Hello All,

I am having a problem with the DEM data I am using obtained from the NED; as you can see in the attached images, there are diagonal/skewed line artifacts running throughout the raster that are (I assume) going to make the results of my stream network and catchment delineations inaccurate. I am curious if anyone has seen this and knows what the cause might be? I can only think that it must result somehow from geographic transformation or something else in the spatial reference, but I have done the same procedure on data from the same source before many times and never experienced this issue. There were no problems as far as I could tell in manipulating the spatial reference information.

Any advice or guidance would be sincerely appreciated. Thanks in advance! :p
