How to fish it · for brown trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
⚠️ Water at 19.8°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots. Otherwise poor — water clarity is in the right range.

About this water

The Croton watershed is the trout answer for New York anglers who cannot or do not want to burn a whole day driving to the Catskills. It is not one neat river: it is a cluster of small tailwaters, reservoir tributaries and public-access fragments across Westchester and Putnam, with browns, rainbows and brook-trout context depending on reach. The value for Rise Daisy is routing and honesty — which branch, which public access, which special regulation, and whether release/temperature/access make it worth the drive.
