Pennington Reservoir is managed as a rainbow trout fishery. This eighteen acre water affords a little more shelter from the prevailing wind than its more exposed neighbours being set in a steep sided valley above Pennington village and overlooks the full extent of Morecambe Bay to the south.
Pennington is stocked with rainbows around the pound and a quarter mark and the odd larger fish. Small brown trout are also present. Fly hatches are fairly typical of an upland fishery and the sedge hatch in particular can be excellent.
