Fishing Recreation Lake Trojan Pond: A Family Angler’s Complete Guide

Fishing at Trojan Pond means bank angling for stocked rainbow trout and warmwater panfish on a small public impoundment in Columbia County, Oregon, just east of Rainier on the former Trojan Nuclear Plant site. The Oregon Department of Fish and Wildlife (ODFW) stocks the pond most springs with 8 to 11 inch rainbow trout, a valid Oregon fishing license covers anyone 12 and older, and the shoreline is open year-round. The cooling-water design gives the pond steady depth, soft bottom sediment, and easy bank access, which is exactly why the site works for first-timers and kids.

Below you will find driving directions from Portland, Longview, and Astoria, a stocking and seasonal calendar, the regulations and license rules, and a tackle list matched to the actual species in the water.

Where Trojan Pond Sits and Why It Became a Fishing Spot

Rainier, Oregon, sits along the Columbia River about 70 miles northwest of Portland, and Trojan Pond is a short drive east of town on the same road that served the former plant. The Trojan Nuclear Plant operated from 1976 until 1992, when voters chose to decommission the facility rather than pursue relicensing. After years of dismantlement, the surrounding lands were turned over to public use, and a small system of cooling-water and runoff ponds became the centerpiece of a community recreation area managed in partnership with the state.

ODFW recognized the site as a useful candidate for routine trout stocking because the ponds are self-contained, easy to access from a public road, and shallow enough to support rainbow trout through the warmer months. Today the pond is a quiet fixture in ODFW’s northwest district stocking rotation, drawing bank anglers from Rainier, Longview, St. Helens, and the northern Portland metro. A stocked day can produce dozens of fish for you and your family in just a few hours.

Getting There, Parking, and What to Expect on Site

The drive to Trojan Pond is one of the simplest parts of the trip, which is part of why the site pulls so many families.

Driving Times From Nearby Cities

• ▸From Portland: the trip runs roughly 1 hour 20 minutes via I-5 north and Highway 30 west toward Rainier.
• ▸From Longview, Washington: plan on about 35 minutes across the Lewis and Clark Bridge on Highway 30.
• ▸From Astoria: the drive is around 1 hour 10 minutes east on Highway 30 along the Columbia River.

Once you turn off the main road, a short paved access road leads to a gravel parking lot with room for about 30 vehicles. The lot is flat and close to the shoreline, which makes unloading a tackle bag, a cooler, and a folding chair a one-trip affair. Restrooms and a couple of covered picnic tables sit a short walk from the water, and there is enough open grass for a pop-up canopy on bright days.

What the Shoreline Looks Like

Your fishing day here is almost entirely bank fishing, so the shoreline is the entire experience. A packed-earth path rings most of the pond, with gravel pads at the most popular spots and a low rail at the deeper side for safety. Bank anglers tend to spread out, so even on a stocked weekend you can usually find a quiet corner. Bring chairs, a small rod rack, and a bait bucket, and you can settle in for the day without bumping elbows.

Safety at a Former Nuclear Site and What It Means for Anglers

The most common question about fishing at Trojan Pond is whether the site is safe, and the short answer is yes, with reasonable context.

Why Fishing Is Permitted Here

When the plant was decommissioned, the Nuclear Regulatory Commission, the U.S. Department of Energy, and the Oregon Health Authority oversaw extensive environmental monitoring of the soils, groundwater, and surface water. Decades of sampling have shown that recreational contact with the pond water and the surrounding soil sits well within safety thresholds for general public use. The site was transferred to the state for community recreation specifically because monitoring confirmed it was safe for walking, picnicking, and angling.

ODFW continues to stock the pond on the same basis it stocks any other public water, and there is no special radiological permit required for you to fish. Standard catch-and-consumption rules apply.

Current Water Quality and Consumption Guidance

Oregon Health Authority publishes statewide fish consumption advisories, and those apply here just as they would at any other Columbia County water. For most stocked rainbow trout, the general guidance is to eat the standard portion size and limit consumption for sensitive groups. Always check the latest OHA advisory before a planned fish dinner, because the recommendations can shift with new data.

Bring water-resistant shoes for the bank, hand sanitizer for after handling bait, and a clean towel for the ride home. The site is family-friendly, but it is still an outdoor shoreline with the usual mud, moss, and slick rocks.

Fish Species Present, Stocking Schedule, and Seasonal Patterns

Trojan Pond is not a deep, complex fishery. It is a small impoundment with a tight species list, and that is exactly why it works so well for a family angler or first-timer.

Rainbow Trout as the Main Draw

ODFW stocks rainbow trout here in the spring, and a second smaller stocking window sometimes opens in early fall depending on fish availability. Typical catchable trout are 8 to 11 inches, which is the perfect size for kids’ rods and ultra-light tackle. On a busy stocking day, limits are common, and the action can stay steady for the first week or two before the trout spread out and the bite slows.

Warmwater Species That Round Out the Action

Largemouth bass hold in the pond year-round, and you can also find bluegill and other panfish along the shallow edges in summer. Bull trout are not stocked here, and ODFW manages the trout program around rainbow genetics. The warmwater fish are a bonus, especially in July and August when surface water temperatures push the trout deeper and small bass or bluegill keep the rods bent.

A Simple Seasonal Calendar

Season	Water Temperature	What You Can Expect
Early spring (March to April)	45 to 55 degrees F	Freshly stocked rainbow trout are active along the shallows; bait and small spinners work best.
Late spring to early summer (May to June)	55 to 65 degrees F	Peak trout action; this is the easiest window for new anglers.
Mid to late summer (July to August)	65 to 75 degrees F	Trout slide deeper; bass and bluegill become the better target on warm evenings.
Fall (September to November)	55 to 65 degrees F	Cooler water pulls trout back shallow; any fall stocking produces another short hot bite.
Winter (December to February)	Below 50 degrees F	Slower fishing, but shore access stays open; small bass and holdover trout are the targets.

ODFW posts the official stocking schedule on its online stocking report, and that page is the single best resource for planning your specific weekend.

Licenses, Regulations, and Daily Limits You Need to Know

Oregon fishing licenses are managed by ODFW, and the requirements for Trojan Pond match the standard statewide rules for public water.

License Basics

• ▸Age 18 to 70: a standard Oregon annual fishing license covers trout, bass, and panfish.
• ▸Age 12 to 17: a youth license is required and costs less than an adult license.
• ▸Under 12: no license is needed, but daily bag and size limits still apply.
• ▸Ages 70+ and disabled veterans: a reduced-fee license is available, and ODFW designates a couple of free fishing weekends each year when no license is required for anyone.

Licenses are sold online through the ODFW licensing portal, at most large sporting-goods stores, and at a number of local tackle shops. Buying online the night before is the easiest way to skip the morning paperwork.

Bag Limits and Catch Considerations

ODFW sets daily bag limits for trout and warmwater species each year, and the specific numbers for the northwest district appear in the Oregon Sport Fishing Regulations booklet. As a general rule for a small stocked pond, expect a modest trout limit designed to spread fish across many anglers. Largemouth bass and bluegill usually have generous limits or are managed as catch-and-release to keep the population healthy.

For a first family trip, catch-and-release on the bass is a smart call so the kids can practice without burning through the daily allowance. Keep a few trout for dinner and release the rest.

Once you know the legal side, the right light rod and a handful of powerbait usually matter more than any other gear choice.

Tackle, Bait, and Bank-Friendly Setups for a Successful Day

The pond is small, the fish are small, and the gear list is short. That is one of the biggest advantages of this spot compared with larger Oregon lakes.

Rod, Reel, and Line

• ▸Spinning rod in the 5’6″ to 6’6″ range: a light or ultra-light action rod handles both trout and panfish.
• ▸Size 1000 or 2000 spinning reel: pair it with 4 to 6 pound test monofilament, or a light 6-pound braid with a 4-pound fluorocarbon leader.
• ▸Bobbers and split shot: pack pencil bobbers, slip bobbers, and a few BB-size split shot for adjusting depth.
• ▸Tackle box basics: size 8 to 12 baitholder hooks, a few small swivels, and micro bullet weights for drifting bait along the bottom.

Bait and Lure Choices

For stocked rainbow trout, a small glob of rainbow-colored PowerBait fished on the bottom under a slip bobber is the most reliable producer. Nightcrawlers work, and so do salmon eggs when in season. Lure anglers do well on 1/16 ounce panfish jigs tipped with a chunk of worm, small spinners in the 1/16 to 1/8 ounce range, and tiny spoons like a 1/16 ounce Kastmaster in silver or gold.

For warmwater panfish, a small piece of worm under a bobber in the weedy corners is almost unfair. Soft plastic grubs in white or chartreuse on a 1/16 ounce jig head will also draw bluegill all summer long.

Realistic Catch Expectations

Plan for a few fish per rod on a freshly stocked weekend, especially in the first hour after sunrise or the last hour before dark. On a slow weekday a few weeks after stocking, a single trout per angler is a solid result. The point of the trip, especially with kids, is the morning on the water, the sandwich at the picnic table, and the chance of one good catch, not a full cooler.

Planning the Trip and Making the Most of a Family Outing

A little planning is the difference between a smooth morning and a frustrated drive home, so build a short routine around the trip.

A Simple Pre-Trip Checklist

• ▸License and ID: buy online the night before, and keep the digital copy on your phone.
• ▸Two rods per person: a light spinning rod for trout and a slightly stiffer rod for bass if the kids want to try something heavier.
• ▸Bait cooler: a small cooler with ice for nightcrawlers, a jar of PowerBait, and a sandwich lunch.
• ▸Layered clothing: mornings are cool even in July, and the wind off the Columbia can pick up by midmorning.
• ▸Sunscreen, hats, water, and a first-aid kit: there is no shade right at the water’s edge, and the closest store is back in Rainier.

Timing Around Stocking and School Schedules

Synchronize the trip with an ODFW stocking event, and aim for the first Saturday after a stocking if you can. Arrive early enough to claim a good spot, because the bank fills up by 8 a.m. on a stocked weekend. Weekday afternoons during school holidays are quieter, and they are a great option for younger kids who nap in the morning.

Once you have a stocked weekend that works, the rest of the year can rotate around smaller goals: a panfish day in July, a bass afternoon in September, and a slow winter trip to see if any holdover trout are still willing.

When to Pick a Backup Instead

If the weather forecast shows steady rain, switch to a sheltered pond or a covered indoor event. If the stocking report slips by two weeks, reschedule rather than dragging a tired kid to an empty shoreline. A backup plan keeps your family calendar friendly, and it means every actual trip to the pond feels like a win. Smaller stocked ponds in the St. Helens and Scappoose area, plus the bank access points on the Columbia River sloughs, are solid backups if the kids want a change of scenery.

The Bottom Line

Trojan Pond is exactly the kind of place that builds lifelong anglers: small, predictable, well-stocked, and forgiving. Show up with a license, a light rod, some rainbow PowerBait, and a willingness to spend a few quiet hours on the bank, and you will leave with a fish or two, a tired kid, and a plan to come back next season.
