"Read only" error message when trying to clip something.

[JamesWarren4]

I'm trying to clip a shapefile of local streams and rivers so that it only shows the ones within the watershed I'm working with. However, when I try to do this, I get the error message pictured here. Any suggestions on how to work with this? The data I'm working with is downloaded from USGS. Admittedly I'm kinda new at this, so it may very well be a really simple fix.

See if this gives you any direction:  https://community.esri.com/thread/52480 

Make you have write permissions to the locations where you are writing the output to.  I suggest sending it to a completely different workspace/geodatabase than where the input resides.
