How do I know if there are fish where I'm fishing?

[Doorhandle]

This is kind of a noob question but I have a spot on the credit river that I really enjoy going to as it is hidden and very private, but I've only ever caught 1 fish at this spot. It was a little pike, not what I expected. I am sitting near the mouth of the credit past the bridge. Is there a good chance that there are a lot of fish in this type of area? There is plenty of cover and tall grass that sticks out of the water.

Any suggestions would be appreciated.

I am fishing a shakespeare gx2 ugly stick with an ultralight reel and 4lbs test mono. I've tried everything from topwaters and crankbaits to jigs and other bait presentations. I just don't know if I'm doing something wrong or if there just aren't any fish around.

Thanks for reading.
