South of Kepple Cove, between the southern ridge of White Side and Catstye Cam is Brown Cove. This also held an artificial tarn, but this is now reduced to a couple of small pools widening the stream. Brown Cove Tarn was another creation of the Greenside mine, a stone faced dam being built in about 1860. The dam is still in place but water now leaks through the base, the extended tarn-bed a smooth patch of luxuriant turf. A water leat passing beneath the north face of Catstye Cam to Red Tarn Beck can still be traced although it is now in ruins. There are also the remains of a level driven into the headwall of Brown Cove, a stone arched entrance leading to an tunnel. Water from Brown and Kepple Coves unites with the outflow of Helvellyn's Red Tarn to form Glenridding Beck, flowing on through the village to Ullswater.
