Red Clay Creek Fly-Only Water at Auburn Valley

Red Clay Creek is Delaware’s second fly-only trout water, and it asks more of an angler than the open stretches of stocked streams. The restricted reach is short, the creek is small, and the rules on gear are strict. This guide explains where the fly-only water is, what the rules require, what to carry, and how to fish a small, clear creek without spooking every fish in the first pool.

Where the water is

DNREC stocks Red Clay Creek from the dam just below the Pennsylvania line about 1.4 miles downstream to the Auburn Valley State Park boundary, which sits next to Creek Road. Within that stocked reach, the fly-only section begins on the downstream side of Yorklyn Road and runs about 0.4 miles downstream, ending at the Auburn Valley State Park boundary.

DNREC publishes boundary coordinates for both ends of the fly-only reach, and the agency’s description is the one to rely on if you are unsure where you are standing. Before you rig up, confirm which side of the boundary you are on. A short walk with the creek on your left or right is not enough, and a spinning rod in the wrong place is a violation.

What fly-only means here

In the restricted water you may use only artificial flies on one single-pointed hook and a fly rod. You may have no more than two flies on the line. Spinners, spoons, plugs and other lures are prohibited, and so is natural bait. That rules out the worm and the corn kernel as well as the metal lure, which surprises casual anglers who assume that only hardware is restricted.

If you have not fished with a fly rod before, Red Clay Creek is not the easiest place to learn. The better first step is the open water on another stocked stream, where you can use either gear. Our guide to White Clay Creek covers a stream that has both a fly-only reach and open water, and the Delaware trout roundup compares the options.

Rules snapshot and what changed

The summary above lists the limit, hours, pre-season closure and stamp requirements, with the date we checked each one. One point is worth repeating. Older news notices described Red Clay Creek as exempt from the two-week pre-season closure. DNREC’s current trout page states the closure for designated trout streams without listing an exemption, so plan on the closure applying here. If you want to be certain for your visit, check DNREC before you go.

Fishing hours begin half an hour before sunrise and end half an hour after sunset. A trout stamp is required during the spring and fall windows shown above. Dates for the 2027 season have not been announced yet.

Gear

A fly rod in the 4 to 5 weight range, around 8 1/2 to 9 feet, is a typical choice for small Mid-Atlantic trout creeks. Many anglers pair it with a floating line and a leader that tapers to a fine tippet, because the water can be low and clear and fish get wary quickly. Small nymphs fished under an indicator or on a short line, and streamers such as woolly buggers, are common starting points. These are suggestions, not requirements, and a short rod can help in places where branches hang over the water.

Since the reach is short, a careful approach matters more than the particular fly. Wear muted clothing, wade slowly and keep your shadow off the water. Barbless hooks make releasing fish easier and are kinder to the trout, although the rule here requires a single-pointed hook rather than a barbless one.

A rod built for this kind of water can make a difference: a lighter tip for fine tippets, a grip that suits a long day of short casts, and guides sized to keep weight down. If you tell us where you fish and what you target, we can build the rod around it.

Fishing a short, clear creek

Approach every pool from downstream so that you cast upstream and the fish are facing away from you. Begin at the tail of a pool and work your way up, covering the near water first so you do not wade through fish. Look for seams where fast and slow water meet, the heads of pools where food collects, and undercut banks and boulders that break the current.

Stocked trout can be less wary than wild fish at first but settle into the same habits quickly. If a pool has been disturbed by a heavy-footed angler ahead of you, move on and come back later. Rest a pool for a few minutes after a hooked fish splashes through it.

Seasons and timing

Spring is the main season, with most of the stocking shortly before and during the spring window, and a fall season runs from the first Saturday in October. DNREC publishes its stocking schedule each year, and the schedule can change, so check it before you plan around a particular date. Cool mornings and overcast days are the most comfortable, and stream temperatures climb in summer.

Safety, access and etiquette

Much of the trout water in this part of Delaware is bordered by private property. Stay on public ground, respect posted signs and park only where it is clearly allowed. Rocks along the stream are slippery, and cold water in spring and fall can chill you quickly, so wear boots with good traction and carry a wading staff if you are unsure of the footing. Give other anglers space, and leave nothing behind.

Eating the fish

DNREC’s consumption advisory lists Red Clay Creek at 3 meals per year for all finfish, based on an 8-ounce adult serving. That is a stricter advisory than the one for most other designated trout waters. Women who are or may become pregnant or breastfeeding and children should follow the state’s guidance. The rules snapshot above carries the exact wording and the date we checked it.
