Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
Perhaps it will be OK to name well-known and often fished larger streams in reports. Do stay away from naming smaller streams, or those not so well known or face the wrath of some angry anglers. Many fly shop sites give regular, sometimes even daily, reports on streams that are well known to most anglers.
