Rena offers a long fishing season, but the character of the river changes substantially between its spring opening, the main summer hatches and autumn grayling fishing. The camp publishes guided-trip periods from May into mid-October, with its main summer period running from mid-June to mid-August. 

May and early June: searching beneath the surface

Early-season fishing can be demanding. Cold water and limited surface activity often make streamers and carefully presented nymphs more relevant than dry flies. Recent opening reports describe anglers working through different depths and finding that clear water still demands a cautious approach, even when fishing larger patterns.

A streamer outfit provides a way to search holding water, but depth and retrieve should be adjusted deliberately. Covering the river efficiently matters more than repeatedly fishing the same presentation. For anglers travelling primarily for rising fish, the more established summer hatches are generally the better focus.

June and July: mayflies and changing feeding windows

As the summer hatches develop, dry-fly fishing becomes a central attraction. Rena supports a broad range of aquatic insects, including mayflies, stoneflies, midges and caddis. The variety means that identifying what fish are taking can be as important as locating the fish themselves. 

During the summer mayfly period, large Ephemera danica can appear alongside much smaller olives and other species. Spinner falls may extend feeding into the evening, creating opportunities that differ from the earlier emergence.

Carry imitations of several stages rather than relying entirely on upright-winged duns. Watch whether fish are intercepting insects beneath the film, taking emerging flies or feeding on spent spinners. A change of profile and presentation can be more useful than moving immediately to a finer tippet. 

July and August: caddis and evening fishing

Caddis activity gives Rena another distinctive phase. Swimming pupae can bring trout close to the margins, with fish feeding actively into the evening and darkness. These opportunities favour anglers who are prepared to adjust their schedule and spend time watching the river before fishing.

The presentation may also change. A natural drift remains important in many situations, while swimming pupae can call for controlled movement. Match that movement to what the insects and fish are doing, with guidance from someone familiar with the hatch.

Hatches can be highly localised, so a quiet stretch does not necessarily reflect conditions throughout the river. The camp’s current advice can help narrow the search. Rena’s summer caddis fishing.

Late summer and autumn: smaller flies and grayling

Dry-fly opportunities continue beyond the main summer period. Small cream and olive mayflies, including patterns around sizes 16–18, can be important during August and September. Grayling become a particularly appealing focus as the season progresses. 

Autumn plans must take account of species-specific protection. The river association publishes a trout protection period beginning in mid-September; later fishing should be planned around permitted species and methods. 

A dry-fly outfit and a separate setup for heavier subsurface work provide a useful starting point. Choose the balance according to your dates and whether the priority is hatches, nymphing or streamer fishing.

Rods, reels and lines

A #4 or #5 single-handed rod is well suited to much of Rena’s dry-fly fishing. For streamers, local guidance recommends outfits in the #5–7 range, depending on fly size and the line required. Local tackle recommendations.

Within the Guideline range, an LPX Tactical 9' #4 or #5 makes a versatile dry-fly and nymph option. The 9'9" models offer additional reach for line management and presentation where that suits the fishing position. Match the rod with a floating line such as Fario CDC WF for delicate delivery or Presentation+ WF for varied dry-fly and nymph work.

For dedicated streamer fishing, the heavier LPX Tactical models provide options for larger flies and sinking lines. Select the outfit around the actual fly and line combination rather than fish size alone. 

A smooth-drag reel and sound connections complete the setup. Rena holds fish capable of testing light tackle, so inspect knots and tippet regularly, particularly after a difficult cast or contact with bankside vegetation.

Leaders and presentation

Carry tapered leaders that can be adjusted for fly size, wind and the current seams between you and the fish. A longer leader can help separate the fly from the line, but it must still turn over accurately.

On smooth water, small differences in drift become visible to both angler and fish. Practise reach casts, controlled slack and gentle line management before the trip. Roll casting and single-handed Spey techniques are also valuable where trees restrict the backcast.

Use tippet strong enough to control and land the fish efficiently. Refusals should prompt a review of fly stage, drift and approach as well as diameter.
