About Black River (Watertown)
The Black River at Watertown is a Lake Ontario river of an entirely different order from its OH namesake -- 1,864 square miles of Adirondack-draining watershed, peak flows above 5,000 cfs in steelhead season, and a hard-water character that rewards heavier gear and longer drifts. The Dexter dam tailwater holds fish through winter; Black River Bay is a fall and spring magnet.
Steelhead run September through April with peaks at the late-October push and the March-April spring run. Fish the dam tailwater + Black River Bay; expect cfs in the thousands all winter. The optimal fishing flow on Black River (Watertown) is 2,000–5,500 CFS — flows above this range are typically too high and stained, flows below run low and clear. The river's long-term median flow is approximately 1,491 CFS, computed from the last several years of USGS gauge readings.
Current conditions (live, updated every 15 minutes): flow 1,490 CFS, clarity clear. Steelhead Addiction's Guide's Report rates the river FAIR as of this reading.

No rain in the window, but flow climbed from 1,316 to 1,573 CFS — that's upstream release, snowmelt, or a tributary feeding in. Water temp shifted held steady. Clarity went Clear. The bite-implication of a clean-water rise without rain is one of fishing's better mysteries. Quiet sky on the way. Conditions should hold.

"Tell Them I'm in a Meeting With a Fish"
Flow is stable in the ideal range — fish are settled and holding in predictable lies.
Clear water — steelhead can see everything, including you. Long leaders, lighter tippet (6lb fluoro), natural colors. Stay low and approach from downstream.
How to Fish It
Fly Selection
Clear water demands subtlety. Natural egg colors (Oregon cheese, pale peach), small stonefly nymphs (#12-#14), and pheasant tails. 6lb fluorocarbon tippet max.
Where to Fish
Stable flows — fish are in predictable lies. Work the classic steelhead water: heads and tailouts of runs, gravel transitions, and current seams. Methodical coverage pays off.
Conditions
Bright skies — fish will hunker in deeper water and shaded lies. Focus on undercut banks, bridge shadows, and deeper runs.

Summer FAQ
What can I fish for on Black River in summer?
Focus on the warm-water species shown above, then use the live flow, clarity, and temperature read to choose shade, rock, current breaks, creek mouths, lakefront structure, and low-light windows.
Steelhead care
Should I target steelhead on Black River in summer?
Usually no. When water is warm, shift to smallmouth, walleye, panfish, pike, or another summer target instead of pressuring stressed trout.

Theoretical line
Good fit (85%)
Points on the dashed line mean the river's flow distribution is log-normal. Bows at the tails suggest multiple flow regimes (snowmelt vs rain events) or sensor artifacts. The math for this river uses log-space statistics, so a poor fit here is a reason to squint at the optimal zone.
