Jeffk beat me to it. A brush hatch of caddis might fill the air but if none of them are on the water....it's nothing more than something cool to see. I was also going to give the march brown spinner flight as an example.
One thing I would say you might want to keep an eye out for is swarm after swarm flying upriver past you. No risers and the 30 minutes later, the pool is boiling with rises but zero bugs in the air. Good chance the swarms went but you to the riffs upstream, did their thing and fell spent. You're a few hundred yards below that egg laying flight and the food conveyor brings them right to you. Search the film closely as spent caddis often lay very flush and are hard to see.
