Smith Reservoir

Trail Bridge and Smith Reservoirs are man-made features just an hour outside Eugene on Highway 126. The 55 acres surrounding Trail Bridge Reservoir is home to numerous campsites, hiking trails and provides great fishing opportunities. Trail Bridge and Smith Reservoirs are a favorite for outdoor enthusiasts who flock the area in the summer. You can spend as much as a weekend in this area or even half a day to enjoy the scenery of Oregon’s Cascades.

On a visit to the camping sites, you should bring a fishing rod and some camping gear to make your time worthwhile. Swimming in Trail Bridge is absolute fun but be warned that the water is cold. In early spring and winters, the reservoir is covered in snow so you must be extra cautious. The McKenzie River feeds the reservoir and so water temperatures stay below 55 degrees Fahrenheit even in the summer.

Apart from swimming, boating is also allowed but you must maintain maximum speeds of 10 mph. Most people prefer to use float tubes and rowboats so they can take in the surrounding scenery at low speeds. The campground is open all year round but the season for Trail Bridge is April - September. If you are an avid angler, take off some time from your swimming activities to catch some hatchery brook and rainbow trout. Whether you derive fun from fishing, swimming, hiking or camping; the Trail Bridge Reservoir will certainly tickle your fancy. There is an activity for the entire family to undertake at the popular Trail Bridge and Smith Reservoirs in Oregon.
