Simpson Reef: Shallow-Water Fishing Off Coos Bay

What Simpson Reef offers and how to fish it

Simpson Reef sits about three miles southwest of Cape Arago, in the lee of the cape's rocky headlands. The reef rises from roughly 40 feet of water and breaks the surface at low tide, creating a shallow, rocky structure that holds lingcod, cabezon, and kelp greenling year-round. The reef is accessible by private boat only — there is no charter service dedicated to it — and the fishing is best during slack water or light current, when you can hold position without drifting hard into the rocks.

The reef's main appeal is that it sits close enough to shore to reach in a small to medium boat, yet far enough out that it draws fewer anglers than the nearshore reefs closer to the harbor mouth. The structure itself is dramatic: rocky pinnacles, crevices, and kelp beds create habitat that holds fish consistently, though the same features that make it productive also make it unforgiving. Snags are common, and the rocks will cut line if you are not careful with your angle and drag setting.

Key Takeaways

Simpson Reef is a shallow rocky structure three miles southwest of Cape Arago that holds lingcod, cabezon, and kelp greenling in 40 feet of water and shallower.
Access requires a private boat; there are no charter services that fish Simpson Reef regularly.
Slack water and light current are essential because the rocks will foul your line if you are drifting hard or cannot hold position.
Jigging with small metal lures and live bait near the rocky pinnacles produces the most consistent results.
The reef is exposed to ocean swell and can become unfishable quickly if conditions deteriorate, so check forecasts and tides before heading out.

Tides and timing at Simpson Reef

Simpson Reef fishes best during the two hours around slack water — the period when the tide is neither flooding nor ebbing strongly. During these windows, you can hold your boat over the structure without constant correction, and your lure stays in the strike zone longer. The reef is exposed to open ocean swell, so even on calm days the water can be choppy, and a strong current running against the swell makes the reef dangerous and unfishable.

Check the tide tables for Coos Bay before you leave the dock. The slack periods are shorter here than they are in protected bays — often only 30 to 45 minutes — so plan to arrive early and be ready to fish the moment the current eases. If you arrive during a strong ebb or flood, you will spend more time fighting the drift than fishing. Low tide exposes the shallowest rocks, which can be a hazard to navigation but also concentrates fish in slightly deeper pockets nearby.

Tackle and technique for rocky structure

Bring jigging rods rated for 15 to 30 pounds of line and pair them with 300-yard capacity reels. The rocks will test your drag, and you need enough line to handle a long run or a snag-and-break situation. Use 20 to 30-pound braided main line — it cuts through the water better than monofilament and gives you more sensitivity to feel the bottom and detect bites. Tie a 12 to 18-inch fluorocarbon leader to the braid using an Albright knot; the leader absorbs abrasion from the rocks and is easier to replace than retying your main line.

Fish small metal jigs — 2 to 4 ounces — in white, chartreuse, or natural colors. Drop them straight down to the bottom, then work them with short, sharp lifts and pauses. Lingcod and cabezon often hit on the drop or during the pause, so stay alert. Live bait — small rockfish, herring, or squid — fished on a simple two-hook spreader rig also works well, especially for cabezon. Keep your rod tip high enough to feel the structure and detect bites, but not so high that you cannot set the hook with a solid upward strike.

Species you will encounter

Lingcod are the primary target. They are aggressive, grow to 20 pounds or more at Simpson Reef, and hit jigs and live bait readily. They are also territorial and often found in the same crevices, so if you hook one, work that spot again — another may move in quickly. Lingcod have sharp teeth, so use a short wire bite leader or accept that you will lose some lures to cut-offs.

Cabezon are abundant and often larger than lingcod. They are bottom-huggers and prefer live bait to jigs, though they will take a jig worked slowly near the rocks. Cabezon have venomous spines on their gill covers — handle them carefully or use a net. The roe is toxic and should not be eaten, but the meat is excellent.

Kelp greenling are smaller — usually 8 to 14 inches — but numerous and fun on light tackle. They are less aggressive than lingcod but steady biters and a good option if the bigger fish are not cooperating. They are excellent eating and make a good backup target when the bite slows.

Navigation and safety considerations

Simpson Reef is marked on charts and GPS, but the rocks extend farther than many anglers expect. Approach from the north or east, never from the south or west where the open ocean swell hits directly. Use your GPS to hold a waypoint over the main structure, but also watch the water for color changes and surface disturbance that indicate shallow rocks. The reef is most dangerous during high tide when the rocks are submerged and invisible.

The area is exposed to wind and swell, and conditions can change rapidly. Check the marine forecast before you leave and be prepared to leave the reef if the swell builds or the wind shifts. A sudden increase in swell can make the rocks treacherous and create a confused sea state that is hard to navigate. Keep your boat in good working order, carry a VHF radio, and never fish Simpson Reef alone if you can avoid it.

When to fish Simpson Reef through the year

Simpson Reef is fishable year-round, but the best conditions are late spring through early fall when the ocean is calmer and the days are longer. Summer brings the most stable weather and the longest slack-water windows, making it the easiest time to fish. Fall can be excellent for lingcod as they feed heavily before winter, but the weather becomes less predictable and the swell often increases.

Winter and early spring are possible but require patience and flexibility. The reef is exposed to winter storms, and you may find yourself driving to the dock only to turn around because conditions are too rough. When the weather does cooperate, however, the fishing can be outstanding because fewer boats are out and the fish see less pressure. Spring tides — the largest tidal swings — create stronger currents and shorter slack periods, so plan your trips around neap tides if you want more time to fish.

Getting to Simpson Reef from Coos Bay

Launch from the Coos Bay area — either at the Charleston boat ramp or at one of the private marinas — and head southwest toward Cape Arago. The run is about 20 to 30 minutes depending on your boat speed and the sea state. Follow the coast south past Cape Arago, then work your way to your GPS waypoint over the reef. The reef is visible on a good fish finder, and you can also spot the rocks on the surface at low tide if the water is clear.

Fuel consumption depends on your boat, but plan for a round trip of 40 to 60 miles. Bring extra fuel if your boat is slow or if you plan to spend a full day fishing. The reef is exposed, so do not linger if conditions deteriorate. Have a clear plan for returning to the harbor before you leave the dock, and know where the nearest shelter is if you need to get out of the weather quickly.

Frequently Asked Questions

Can I fish Simpson Reef from shore or a kayak?

No. The reef is three miles offshore and exposed to open ocean swell. A kayak would be unsafe, and there is no shore access. You need a private boat with enough power and stability to handle the open water and return safely if conditions change.

What is the best time of day to fish Simpson Reef?

Fish the slack-water periods, which occur around the time of high tide and low tide. The exact timing changes daily with the tide tables. Arrive early and plan to fish the 30 to 45 minutes when the current is weakest. The time of day — morning or afternoon — matters less than catching the slack water.

Do I need a special license to fish Simpson Reef?

You need a valid Oregon saltwater fishing license. Lingcod and cabezon have bag limits and size restrictions that vary by season, so check the current Oregon Department of Fish and Wildlife regulations before you fish. Regulations change, so verify the rules for the year you plan to go.

What should I do if I get snagged on the rocks?

Set your drag to slip before you fish, so a hard snag breaks your line rather than pulling your boat into the rocks. Keep extra jigs and leaders on board. If you snag, try backing down slowly to change the angle, but do not risk your boat. Losing a lure is cheaper than a repair bill or worse.

Is Simpson Reef crowded?

Simpson Reef sees fewer anglers than the closer nearshore reefs, but it is not empty. Summer weekends can bring several boats. Weekdays and shoulder seasons are quieter. The reef is large enough that boats can spread out without interfering with each other, but arrive early if you want the best position over the main structure.
