Moste Reservoir (Sava Dolinka)

Moste Reservoir (Sava Dolinka) terrain map

RD Jesenice's trophy water, and the odd one out in this pack: sixty hectares of the Sava Dolinka held up behind the Moste dam, in a gorge that looks like nowhere else on the river.

How these readings are sourced

No gauge reads this impoundment — level is set by hydro operation at the Moste dam, not by rainfall, so treat any flow-derived read as weather-only context rather than a measurement of this water.

How to fish it · for Trout
When
The murrough is on. Sedge may also come into play as the day warms. Calm conditions may limit drift fishing — consider buzzers or dry fly if fish are rising.
Where
Start with Elk Hair Caddis (12-16) on a on a floating line. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Elk Hair Caddis (12-16) on a on a floating line. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Bank

Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.

Stillwaters exist and can be worth fishing, but this is a starter pack compared with the stronger Slovenian river identity.

About this water

RD Jesenice's trophy water, and the odd one out in this pack: sixty hectares of the Sava Dolinka held up behind the Moste dam, in a gorge that looks like nowhere else on the river. It fishes as a stillwater — off the bank where the level lets you, or from a belly boat, which is how most people do it and which the club will hire you. Fly only, catch and release, no exceptions. Brown trout grown heavy on reservoir feeding, rainbows, grayling that have dropped down out of the river, and chub, which are more entertaining than anyone quite admits. The level is dam-controlled rather than rain-controlled, so the usual river read — it rained, therefore it rose — does not hold here, and a bank you walked in August can be under water after a wet week. Stay off the last hundred metres above the barrier.

  • Reservoir
  • Limestone
Why this score
  • Murrough is in its seasonal window, boosting the chance of targeted feeding.
Directions
Seasons & zones
  • Trout 1 March30 September

    Slovenian default dates. This is a trophy district with its own regulation (Pravilnik o trofejnem revirju Jesenice – Moste) — the operative dates come from the RD Jesenice permit, not the national default. Check before travelling.

  • Grayling 16 May30 November

    Slovenian common default for lipan. Permit and district controlled — confirm against the trophy-district rules.
