Merging GPS Points to Polyline

Hello everyone. I am currently working on a project with a local county, making a fish barrier map represented by stream polyline data. The problem is, the data that was collected were from GPS points taken in the field by a biologist. A lot of these points don't actually fall on the stream, and in most cases are anywhere from 1-100 meters off the polylines. Yet they don't want to actually physically move the points, but rather just bring that data into the polylines. I am having trouble figuring out how to do this, a simple join doesn't work because there are no like fields in the attribute table to join the data with, and I can't run an intersect or merge either since the points and polylines don't actually physically match up. I have been reading up on linear referencing, but can't quite get it to work. Is there any tool in which I could set a 100 meter buffer on all the polylines and then merge all the points that fall in the buffer? Any help or ideas would be appreciated, I hope I didn't make this to confusing :confused:
