World Class

Fly Fishing Lodge

in Idaho.

The history of Three Rivers Ranch is what makes it such a unique place to stay. Lonnie Allen has been the owner and operator of Three Rivers Ranch since 1987. Her great grandparents, Fred and Berta Lewies homesteaded and started the Warm River Inn and Rendezvous Dance Hall in Warm River in the 1920’s. The business grew into a small resort area with a café, dance hall, cabins and train stop for tourists headed to Yellowstone National Park. In 1974, Lonnie’s parents, Harry and Lillian Lewies approached The Orvis Company about opening one of the first Orvis endorsed fly fishing lodges. In order to receive such an honor, a lodge must meet the rigorous standards that Orvis expects from a fly fishing lodge.

Through Lonnie’s care the ranch has become one of the most treasured and highly sought after fly fishing destinations in the world. The exceptionally high standards that Three Rivers upholds will ensure that you will experience great service, great fishing and experienced, professional guides and staff.

Fred & Berta Lewies


Fred & Berta Lewies homesteaded the land Three Rivers Ranch and Warm River is located.  Fred fought in the Boer War in South Africa and Berta was from Switzerland.  To say they have an interesting story would be a serious understatement.  Hear him tell the story:

Harry & Lillian Lewies

Owners (1957-1986) – Lonnie’s Parents

Harry and Lillian both grew up in and around Warm River and helped run the Warm River Inn on Three Rivers.  After Harry returned from World War II (Purple Heart, Bronze Star, Oak Leaf Cluster) they married and shortly after took over operations of the family business.  In 1973, he decided to begin catering to fly fishing enthusiasts.  The following year he shortened the business name to “Three Rivers Ranch” and through the partnership with Orvis, became the first Orvis Endorsed Lodge.

Under her care, the business has won Orvis Lodge of the Year.  She operates the lodge, 4 full-service fly shops across Idaho, a screen printing and design shop, and an award-winning tequila brand Volans Tequila.  She was appointed by the Governor of Idaho to the travel council and received the Orvis Lifetime Achievement Award.

Justin Allen

Justin grew up among the heroes of the fly fishing industry in Warm River.  He has done almost every job the ranch has to offer and knows the business from all sides.  If you’ve booked a trip at Three Rivers Ranch, chances are you’ve spoken to Justin.  He is a licensed guide, avid outdoorsman, expert angler, husband & father of a baby girl, and is pretty awesome on the grill!

Chad Allen

Karen Roberts

Executive Chef

Karen Roberts has been Head Chef at Three Rivers Ranch since 1982.  When asked about her success she said, “When you work with people you consider your family and your friends, it’s hard to imagine not being a part of that. I love being able to have the freedom to create meals and desserts with the freshest ingredients. I’m excited to try new things, and I prefer to make everything I can from scratch. My goal is to find textures and tastes that are delicious to all palates. Not just to one person, but to everyone.”  Her ability to create mouthwatering creations make each meal feel like a celebration.

Doug Gibson

Head Guide

Doug has been head guide at Three Rivers Ranch since 1973.  He still guides a couple days per year (one client has fished with Doug for over 40 years!) and still works helping in various aspects around the ranch, including tying his custom tied flies for the shop.  He has guided over 4000 days, invented over 15 (widely used) flies, won the Orvis Guide of the Year Award, and the Orvis Lifetime Achievement Award.


Every guide at Three Rivers is a veteran angler and is part of the family. They know the waters from top to bottom and precisely how to fish them, regardless of the time of year. Whether you are fishing as a single angler, among a large group, or have special needs our guides work together to make your fishing experience more pleasurable.

Paul Beckley


Paul was born in San Jose, California. He began fly-fishing at 27. ‘I was hanging out with a buddy in Portland, Oregon, he handed me a fly rod and I’ve been hooked ever since.’ Paul has been guiding for Three Rivers since 1981 and “still has the passion”. “My favorite stretch of river is the Fall River. It’s the best rainbow wade fishery in eastern Idaho.” Paul has fished all of the Rocky Mountain States and parts of Canada. ‘Three Rivers Ranch is better than any place I’ve been around. The guides are professional and have so much experience to offer. Lonnie’s attention to every detail about the ranch makes each guests experience special. The guides are like brothers and there’s a real family atmosphere that guests become part of.’ Paul lives in Warm River, Idaho and has two sons.

Cliff Weisse


Cliff was born and raised in Bergenfield, New Jersey, where he taught himself to fly fish when he was 12 years old. Growing up he enjoyed fishing the Beaverkill, Delaware, and other small brooks. He became a guide in 1987 and has been with Three Rivers since 1988. “What I like best about being with Three Rivers is that we are able to proIdahodsdvide excellent fishing all season long because of the diversity of the rivers Three Rivers is licensed on. We typically fish with guests for 4 to 5 days rather than only 1 or 2. This gives me a chance to actually teach my clients something new rather than putting the emphasis on catching fish right now. I get a great deal of satisfaction out of seeing folks make improvement. We can enjoy just being on the river, looking at wildlife/flowers, learning about the insects and catching fish without my guests feeling like they have to fish hard all day to get the most from their guided trip.” Cliff and his wife Lisa live in Island Park, Idaho. They raise English Setters and travel extensively to hunt every fall.

Skip Mullen


Skip grew up in many beautiful areas throughout the greater Northwest which led to his love of fly fishing and spending time in the outdoors. Both his grandpa and mother were instrumental in teaching Skip to fly fish.  His grandfather started him fishing with a fly rod and spinning reel, when he was “maybe three”,  which Skips  says helped him get the feel for fly casting with a fly rod when he was very young.

Skip has spent the majority of his life on the water fishing, teaching, exploring or guiding. He started  guiding for Three Rivers Ranch in 1996. He loves his clients, the area and his ‘extended family’ at Three Rivers. These relationships are what has kept Skip part of the Three Rivers family for so many years.

During Three Rivers off season, Skip has spent the past twenty years essentially pioneering fly fishing in the Aysen Region of Chilean Patagonia. Together, with his partners he has been instrumental in designing new fisheries, starting two fly fishing lodges- Dragon Fly Lodge and Tomango Lodge and also designed and manufactured special boats (part jet boat/ part cataraft) that allow anglers in these regions access to water on both rivers and lakes that very few other outfitters have access to.

Todd Allen


Todd grew up in Nampa, Idaho. His dad taught him to fish on various lakes, rivers, and creeks in southwestern Idaho when he was about 12 years old. After graduating from University of Idaho, Todd started guiding in 1996. He has been with Three Rivers Ranch since 2002, prior to the ranch he guided in Alaska and Chile. ‘The beautiful area and diversity of fishing is what has kept me at Three Rivers. Any stretch of river that’s fishing the best is my favorite.’ In 2009, Todd went to Brazil and fished for peacock bass on the Amazon drainage. Along with fishing, Todd also enjoys bird hunting and golfing. He lives in Ashton, Idaho with his wife and two kids.

Eric Grigg


Eric was born and raised in Soda Springs, Idaho. He began fly-fishing around 6 years old when his mother taught him while growing up in southeast Idaho. Eric attended college at Montana State University, where he earned a degree in Biotechnology. His enthusiasm for fishing continued throughout college and eventually landed him at Three Rivers Ranch where he began guiding in 2003. ‘There’s a great camaraderie at the Ranch. Lonnie is great to work for and the guides are not only co-workers but also friends. We often take off and fish together when we have free time or during the off-season. I grew up fishing the South Fork of the Snake River and love those lower stretches, but I must say the lower Henry’s Fork is awesome because of the size and quality of the fish.’ Eric lives in Ashton, Idaho.

Nick Minor

Fly Shop Manager / Guide

Nick was born and raised in Boise, Idaho where his dad taught him to fish on the South Fork of the Boise River, Salmon, and Owyhee at the ripe old age of 7. He was rowing a boat by 16. Once out of high school, Nick’s excitement for fishing took him on a road trip through Eastern Idaho, and parts of Wyoming and Montana looking for just the right place to begin guiding. His search brought him to Three Rivers Ranch, where he completed guide school and began his career as a full time guide in 2005. ‘I love the challenge of the Henry’s Fork. It offer’s good, dry-fly fishing, large wild rainbow, browns and unbelievable scenery.’ Nick lives in Boise, Idaho. He enjoys fishing, water aerobics, golfing and college football in his spare time.
