What You'll Find at Discovery Park

Discovery Park sits where the American River meets the Sacramento River, and it's one of the most accessible fishing spots in the city. The park holds striped bass, largemouth bass, catfish, and American shad depending on the season. The American River channel is slower and shallower than the Sacramento main stem, making it easier to wade or fish from shore, while the Sacramento River itself runs faster and deeper—two different fisheries in one location.

The park covers 302 acres and has parking, restrooms, and a boat launch. Most of the fishing happens from the banks or from small boats launched at the ramp. The water is tidal here, which means the depth and current change throughout the day. That tidal influence brings fresh fish in and out, so timing matters more than it does on most inland California rivers.

Key Takeaways

  • Striped bass move through Discovery Park in spring and fall, with the best fishing usually in April through May and September through October.
  • The American River channel is shallower and slower than the Sacramento main stem, so choose your bank based on which species and conditions suit your gear.
  • Tidal flow changes the depth and current several times a day, so check tide tables before you go—incoming tide usually brings more fish to the shallows.
  • A California fishing license is required for all anglers 16 and older, and striped bass have a daily limit of two fish with a 18-inch minimum size.
  • The boat launch is open during daylight hours, and parking fills quickly on weekends during spring and fall striper season.

Striped Bass: Spring and Fall Runs

Striped bass are the main draw at Discovery Park. They move upriver from the Delta in spring (April through May) and again in fall (September through October). During these windows, they stack in the deeper holes and channel bends where the American River joins the Sacramento. The incoming tide pushes them into shallower water, so fish the two hours before and after high tide for the best chance.

Live bait works well here—threadfin shad, anchovies, or live shiners cast near structure or deeper holes. Casting plugs and swimbaits also takes fish, especially early morning and late afternoon. The stripers here run 4 to 12 pounds on average, with occasional fish over 15 pounds. The daily limit is two fish at 18 inches minimum, and you must have a valid California fishing license.

Outside the spring and fall runs, stripers are less predictable. Some stay year-round in the deeper Sacramento channel, but they're scattered and harder to locate. Winter and summer fishing is possible but requires more patience and local knowledge.

Largemouth Bass and Catfish Year-Round

Largemouth bass live in Discovery Park all year, especially in the slower American River channel and around the tule-lined banks. They're smaller than the stripers—mostly 1 to 3 pounds—but they're consistent. Soft plastics, small swimbaits, and topwater lures work in the shallows, particularly early morning and at dusk. The best spots are the inside bends where current slows and vegetation grows.

Catfish are also present year-round and are most active at night. Chicken liver, cut mackerel, or prepared stink baits fished on the bottom near deeper holes will take them. Catfish here run 2 to 8 pounds, and there's no daily limit in California. They're a good option if you want to fish after sunset or if striper season hasn't started.

Understanding Tides and Water Flow

Discovery Park is tidal water, which means the Sacramento River's level rises and falls with the Delta tides, not with rainfall or dam releases upstream. High tide pushes water upriver and into the shallows; low tide pulls it back out. This cycle repeats roughly every 12 hours and 25 minutes, so the tide times shift about 50 minutes later each day.

Fish move with the tide. Incoming tide concentrates them in shallow flats and along banks where they feed. Outgoing tide pushes them toward deeper channels. Check a tide table for Sacramento or the Delta before you fish—NOAA publishes free tide predictions online, and many fishing apps include them. Plan to fish the slack water (the 30 to 60 minutes around high or low tide) and the first two hours of incoming tide for the most active feeding.

Water clarity varies. After heavy rain, the American River channel can turn brown and murky, which can slow fishing. The Sacramento main stem usually stays clearer because it's deeper and has more flow. If one side is too dirty, move to the other.

Where to Fish and How to Access the Water

Discovery Park has several fishing zones. The American River channel (the northern arm) is shallower, slower, and better for wading or fishing from shore. The Sacramento River side (the eastern and southern banks) is deeper and faster, better suited to boat fishing or casting from higher banks. The boat launch is on the Sacramento River side and costs a day-use fee—check the Sacramento County Parks website for current rates.

Bank fishing is free and doesn't require a boat. Walk the levee trails along the American River channel or the Sacramento River banks. The levees are public access routes, and you can fish from them or drop down to the water's edge in most places. Parking is available near the boat launch and at the main park entrance. Arrive early on weekends during striper season; the lot fills by mid-morning.

Wading is possible in the American River channel during low tide, but the bottom is silty and uneven. Wear wading boots with good grip. The Sacramento River is deeper and has stronger current, so wading there is riskier and not recommended unless you're experienced.

Seasons and What to Expect

Spring (April–May) is peak striper season. Fish are aggressive, water is warming, and the incoming tide brings them shallow. Expect crowds on weekends. Bring multiple lure types and be ready to adjust if one isn't working.

Summer (June–August) is slower. Stripers move deeper and out toward the Delta. Largemouth bass and catfish are more reliable. Water can be warm and low, and algae blooms are possible. Early morning and evening fishing is best.

Fall (September–October) brings another striper run as fish move upriver again. Conditions are similar to spring—good fishing, crowds, and active fish. October can be excellent.

Winter (November–March) is quiet. Stripers are scattered, water is cold, and fewer anglers fish. Catfish and largemouth bass are still around, but the bite is slower. This is a good time to scout locations and learn the water without pressure.

Gear and Tackle Recommendations

For stripers, bring a medium-power spinning rod (6 to 7 feet) with 10- to 15-pound braided line or 12- to 17-pound monofilament. A 1/4- to 1/2-ounce jig head with a soft plastic shad, a 2- to 3-inch swimbait, or a small plug (2 to 3 inches) will cover most situations. If you're using live bait, a 1/0 to 3/0 circle hook on a simple slip-sinker rig works well.

For largemouth bass, a 6- to 6.5-foot medium-power rod with 8- to 12-pound line is standard. Soft plastics (4 to 6 inches), small swimbaits, and topwater lures are effective. For catfish, a heavier rod (medium-heavy) and 15- to 20-pound line handle the bottom fishing and occasional snags better.

Bring polarized sunglasses to spot fish and structure. A headlamp is useful if you're fishing dawn or dusk. Sunscreen, water, and a small cooler are essentials. If you're wading, neoprene waders and felt-sole boots are worth the investment.

Frequently Asked Questions

Do I need a boat to fish Discovery Park?

No. Bank fishing is productive, especially along the American River channel. A boat gives you access to deeper water and more ground, but many anglers catch fish from shore. The boat launch is available if you have your own small boat or can rent one.

What's the best time of day to fish here?

Early morning (sunrise to 9 a.m.) and late afternoon (4 p.m. to sunset) are most active. Tide timing matters more than time of day—fish the incoming tide and slack water around high tide, regardless of the hour. Night fishing for catfish is also productive.

Can I keep striped bass I catch?

Yes, if they're 18 inches or longer. The daily limit is two fish per angler. You must have a valid California fishing license. Check the current regulations on the California Department of Fish and Wildlife website before you go, as rules can change.

Is the water safe to fish in?

Generally yes, but water quality varies. After heavy rain, the American River can be murky and unsafe for wading. Check local water quality reports if you're concerned. Avoid swallowing river water, and wash your hands before eating.

How much does it cost to fish Discovery Park?

Bank fishing is free. Day-use parking is a small fee (check Sacramento County Parks for current rates). If you launch a boat, there's an additional launch fee. A California fishing license is required and costs vary by residency and license type.
