This river has all the ingredients necessary to make it one of the finest quality trout streams in the world except one. It does not have enough low temperature input to sustain a large population of trout through the warming summer. But don't let that stop you from enjoying the magic of the Saco's season. Just looking at this fly chart supplied by North Country Angler will assure you that the river is a very futile environment. This well stocked shop has a high level of knowledge and can arrange top notch licensed guide service as well.
Last year on a Friday morning I started with a fine Brown Trout of seventeen inches or more. I make it a habit to look into the river to see what is happening. What I saw were the dead mayflies floating down with clear wings. You may not make the correct choice every time but at least you have the possibilities. I learned later that the spinner fall was amazing the evening before. The morning fish can also be fooled with size 16 Adams, Red Quills and Yellow Sally's. One thing needs to be made clear, this is a tough river at times and what worked yesterday, let alone last year might not today.
On Saturday morning I started where I left off the evening before. What I had learned condensed my fly choices and proved far more successful. Working small and making frequent changes was the order of the day. Blue Wing Olive, Adams, Red Quill, Yellow Sally, Rusty Spinner and Black Woolly Buggers accounted for most of the connections. The comparadun style worked particularly well followed by parachutes.
As the head lamps came on I hooked my last fish of the day. I had worked this fish a number of times and interest with rejection was the pattern. This was a real nice size Brown that was as large as the stocking truck had delivered. I picked out the smallest Parachute Adams with an orange post that was in my box. The fish rose and sipped the fly and was solidly hooked. The charge was instantaneous and quick, directly across the pool making my reel scream with delight. And then nothing.
The Saco is as close to perfect as you can get here in the east. Some say the kayaks and canoe hatch is a problem but I watch the boats go by and the trout start feeding before the wake has left the water. They don't schedule drop offs very early or late and leave the best of the day's events from disturbance. The people do apologize way too much.
Give yourself one full day if you can. This is a river in the most pleasing of surroundings that should not be missed.
