Reservoir fishing: make a large water manageable

On a broad, exposed water, choosing a safe bank and a repeatable area matters more than casting to the horizon.

By the Rodmere team

Use the reservoir's own information

Reservoir access, operating levels, boats, wading, permitted areas and methods vary widely. Confirm booking or permit, applicable licence and season, opening hours, gate arrangements and emergency instructions. Read current notices on arrival because banks can change as water levels move.

Identify no-fishing zones, dam structures, draw-off towers, sailing areas and working infrastructure. Never cross barriers or assume a temporarily exposed bank is open.

Plan for exposure

Wind can build waves and make casting, footing and return routes difficult. Check the forecast and choose a bank where the method can be controlled. Carry suitable layers, food, water, phone and any required flotation equipment. Leave before deteriorating visibility or weather turns a long walk into a problem.

Break the water into reachable zones

Look for points, bays, stream entries, shelves, weed lines and wind effects that can be fished from a permitted position. Compare a near line with one open-water line rather than scattering casts. Fish may pass close to the bank, particularly where depth changes quickly.

Match fly line, feeder or float tackle to the venue's advice and expected conditions. Distance is useful only when the rig still lands, fishes and can be retrieved safely.

Landing is part of swim choice

Before casting, find where a fish can be netted without stepping onto slippery rock, deep margins or unstable mud. Set care equipment there and keep the path clear. If falling water exposes soft ground or steep edges, relocate rather than improvising.

Prepare with the wind guide and, for trout, the first-day stillwater plan.
