Otter Creek
Otter Creek is Vermont's longest river at 112 miles, offering diverse fishing from cold-water brook trout in headwaters to mixed trout and warmwater species in lower sections. Cold tributaries like the New Haven and Middlebury Rivers provide excellent trout habitat where they meet the main stem.
Current Conditions
Overview
Otter Creek flows north through western Vermont's Champlain Valley before emptying into Lake Champlain. The upper sections provide brook trout water, while the middle and lower sections offer mixed fisheries with trout found near tributary junctions and below dams. The creek is best known for its tributaries, which provide excellent cold-water trout habitat.
Water Characteristics
Long river system with varying character. Upper sections cold and clear with brook trout. Lower sections slower and warmer with mixed species. Spring-fed tributaries provide cold water refugia.
Wading & Float Guide
Varies significantly. Upper sections are smaller and easily waded. Lower sections are larger and slower with soft bottom in places. Choose sections carefully.
Multiple sections
Otter Creek is suitable for canoeing and kayaking. Focus on upper sections and tributary junctions for trout.

Seasonal Fishing Guide
Spring
Spring fishing best in upper sections and below tributary junctions. Brook trout active as waters warm. Mayfly and caddis hatches begin in May.
Summer
Summer fishing best in headwaters and near cold tributary inputs. Lower sections warm and support warmwater species. Focus trout fishing at tributary junctions.
Fall
Fall provides excellent fishing as temperatures cool. Brook trout in spawning mode; respect spawning areas. Good time to explore tributaries.
Fishing Pressure & Local Tips
Light to moderate depending on section. Tributaries receive most fly fishing pressure. Main stem less crowded.
Local Knowledge
Focus on Otter Creek's quality tributaries (New Haven River, Middlebury River) for best trout fishing. Main stem best at tributary junctions where cold water enters.
Species Present
Brook Trout
The brook trout is widely considered the most beautiful freshwater fish in North America, and catching one in a pristine Montana mountain stream is an experience that captures the essence of backcountry fly fishing. Despite their common name, brook trout are not true trout at all; they are a species of char (genus Salvelinus), more closely related to lake trout and Arctic char than to rainbows or browns. Native to eastern North America from Georgia to Hudson Bay, brook trout were among the first salmonids introduced to Montana's waters in the late 1800s and have since established self-sustaining populations in cold, high-elevation streams and lakes throughout the state. In Montana, brook trout thrive best in small, cold headwater streams and high mountain lakes where competition from larger trout species is minimal. In these environments, they are often the dominant, or only, salmonid present. The trade-off is size: Montana stream-dwelling brook trout typically range from 6 to 10 inches, with fish over 12 inches considered noteworthy in most waters. What they lack in size, however, they more than make up for in beauty and willingness to eat a fly. Brookies are aggressive feeders that will strike attractor dry flies, nymphs, and small streamers with enthusiasm, making them an ideal species for beginning fly anglers and a delightful quarry for anyone who appreciates small-stream fishing. Brook trout do present a conservation paradox in Montana. While they are a beloved and beautiful gamefish, they are non-native and can negatively impact native species, particularly Yellowstone and westslope cutthroat trout. In headwater streams, brook trout often outcompete cutthroats for food and spawning habitat due to their higher reproductive rate and earlier maturation. As a result, Montana FWP has implemented brook trout removal projects on some streams to restore native cutthroat populations. In many waters, liberal harvest limits for brook trout are encouraged to reduce their numbers and benefit native fish. Anglers can enjoy excellent brook trout fishing while actively helping conservation by keeping a few for the pan.
Brown Trout
The brown trout is the most cunning and elusive trout species swimming in Montana's rivers, and it rewards patient, skilled anglers with some of the state's most memorable catches. Originally native to Europe and western Asia, brown trout were first introduced to North American waters in 1883 and arrived in Montana shortly thereafter. They have since established robust, self-sustaining populations in virtually every major trout stream in the state, from the legendary spring creeks of the Paradise Valley to the sweeping runs of the lower Madison and the deep pools of the Bighorn. Brown trout grow larger than any other trout species in Montana, and fish exceeding 24 inches are caught with regularity on premium waters. The lower Madison River, the Missouri River below Holter Dam, and the Bighorn River are particularly renowned for producing trophy-class browns. Unlike rainbows, brown trout spawn in the fall (October through November), and their aggressive pre-spawn behavior creates an exciting window for streamer fishing as large males become territorial and attack anything that enters their domain. Browns are notably more nocturnal than other trout species, and many of the biggest fish are caught during low-light conditions. What sets brown trout apart from other species is their wariness and selectivity. Large browns are notoriously difficult to fool, often refusing flies that are even slightly off in size, color, or presentation. They tend to establish and defend prime feeding lies (undercut banks, logjams, deep pools, and boulder gardens), and an angler who learns to read water and identify these holding spots will consistently catch more and larger fish. This combination of difficulty, size potential, and intelligence makes the brown trout the most prized quarry for many serious Montana fly fishers.
Rainbow Trout
The rainbow trout is Montana's most widespread and popular gamefish, celebrated for its explosive surface strikes, aerial acrobatics, and willingness to take a well-presented dry fly. Native to Pacific Coast drainages from Alaska to Mexico, rainbows were first introduced to Montana's waters in the late 1800s and have since established thriving populations in nearly every major river system in the state. On legendary waters like the Madison, Missouri, and Bighorn, wild rainbow trout grow fat on prolific insect hatches and provide some of the finest dry-fly fishing in North America. Rainbow trout in Montana display remarkable variation depending on their home water. Fish in nutrient-rich tailwaters like the Missouri River below Holter Dam can exceed 20 inches with regularity, their deep bodies and broad tails reflecting the abundant food supply. Freestone river rainbows, such as those in the upper Madison and Gallatin, tend to be leaner and more athletic, shaped by faster currents and colder water temperatures. In many Montana rivers, rainbows spawn in the spring from March through June, and anglers should be mindful of spawning redds during this period to protect future generations of fish. Rainbows are arguably the most versatile trout species for fly anglers. They respond well to dry flies during hatches, aggressively chase streamers, and feed heavily on nymphs subsurface throughout the year. Their fighting ability is legendary: a hooked rainbow will often launch itself completely out of the water multiple times during a battle. Montana's catch-and-release regulations on many blue-ribbon streams have produced exceptional rainbow trout fisheries with high densities of large, healthy fish that continue to draw anglers from around the world.
