David, I was referring to legal access by a public access point. Never mentioned trespassing on anyones land to get to the water. Most of us here are aware of that can land you a ticket or jailtime.
The trash Flygoddess mentioned is prevelant along the lower Provo river, which runs along the highway. I'll be the first to admit that residents here aren't the cleanest when it comes to litter. I've never seen a flyfisher leave a dirty disposable diaper by a riverbank or a shoe or flipflop or a McDonalds bag.
