Every named stream in the Adirondack Park — the feeder waters that line the High Peaks valleys and fill the ponds.
Walkjer Brook flows through the Paradox Lake region — a stream without published fish survey data or mapped DEC access, which in this part of the eastern Adirondacks usually means it's either a seasonal tributary or a connector between bigger waters that don't get stocked or managed for angling. The Paradox Lake watershed drains east toward Lake Champlain, and most of its named brooks run cold and fast in spring before dropping to trickles by August. If you're exploring the area, start with the known access points on Paradox Lake itself and work upstream from there — Walkjer Brook is likely a bushwhack proposition.
West Mill Brook drains west out of the Paradox Lake basin — a small tributary system in the broader Lake Champlain watershed, tucked into the low hills east of Schroon Lake. The stream doesn't show up on most recreation maps and there's no formal trail or public access noted in DEC records, which usually means it's crossed by old logging roads or reached by way of posted land. No fish data on file, though small freestone brooks in this drainage typically hold wild brookies if the gradient and flow are right. If you're poking around the Paradox Lake area and see a blue line on the quad map, this is one of those — worth investigating if you're already there, but not a named destination.
