Preston sits in the Bear River valley in the far southeast corner of Idaho, and the fishing around it splits cleanly into two types: still water and moving water. On the lake side, Condie Reservoir, Strong Arm Reservoir, and Horse Lake give you options ranging from a quick half-day outing to a full camping trip, with Maple Grove Campground sitting right on the water if you want to wake up and fish before breakfast. The river fishing is anchored by the Bear River and its tributaries, with access points at Redpoint Campground, Willow Flat Campground, Albert Moser, and Egan Basin Guard Station spreading you out along different stretches so you're not stacking up on the same hole. This is not a destination that gets heavy out-of-state traffic, which is part of the appeal. The crowds you'd fight at more famous southeast Idaho waters mostly don't show up here. That said, it's real fishing with real conditions — water levels on the river sections move with snowmelt and irrigation draws, and the reservoirs can fluctuate. Franklin County sits in Idaho Fish and Game's Magic Valley Region, so check current regulations before you go, especially for any slot limits or gear restrictions that apply to specific waters.
The lakes and reservoirs in the area, including Condie Reservoir, Strong Arm Reservoir, and Horse Lake, typically hold warmwater species alongside stocked trout. The river access points at Redpoint Campground, Willow Flat Campground, Albert Moser, and Egan Basin Guard Station put you on Bear River tributary water where trout are the primary target. Check Idaho Fish and Game's current stocking reports for the most accurate picture of what's been put in recently.
Late spring through early summer is productive on the river sections once runoff settles and water clarity improves, usually by late May or June depending on the snowpack year. The reservoirs fish well in spring when water temperatures are still cool and again in fall. Summer midday heat pushes fish deep in the lakes, so early morning and evening sessions at places like Condie Reservoir and Horse Lake will outperform a noon arrival.

Not necessarily, but several of the best access points are tied to campgrounds. Redpoint Campground, Willow Flat Campground, and Maple Grove Campground all provide river or lake access alongside overnight sites, so staying on-site is the most convenient option if you're fishing multiple days. Egan Basin Guard Station and Albert Moser offer river access without requiring you to camp.
A medium-light spinning rod in the 6- to 7-foot range handles most situations on the Bear River tributaries accessed from spots like Albert Moser and Willow Flat Campground. Small spinners, worms, and lightweight jigs cover the bases. If you're fly fishing, a 4- or 5-weight rod with standard nymph and dry-fly patterns for mountain streams is appropriate for these waters.
The reservoir and lake spots are the better call for beginners and younger anglers. Condie Reservoir and Horse Lake offer relatively calm water, easier casting situations, and the kind of steady action that keeps kids interested. The river sections at places like Redpoint Campground can work for families too, but moving water requires more attention to footing and reading current, so it suits anglers with at least some experience.
