Wade4/100
Wading is the most sensitive plan today. Use protected edges only, avoid crossings, and downgrade quickly if clarity or current feels wrong.

River strategy
Fish only the legal water, and do not wade by default.
Hot Creek is technical, clear, and famous for trout, but the geologic site has serious geothermal hazards and closure rules. Use the fishing access sections, check current rules, and keep presentations light.
- Use RiverReports and USGS 10265150 for current flow context near the flume.
- Do not fish or enter closed geothermal areas at the Hot Creek Geologic Site.
- Respect Hot Creek Ranch private water and reservation-only access.
- Plan on tiny midges, BWOs, scuds, caddis, and bank-first presentations.
Why this score moved
Water temperatureLowers score
USGS water temperature is about 94F. Do not pressure trout or salmonids in warm water.
Best mode nowLowers score
Bank / edge: Bank and edge fishing is the safer default when water is high, pushy, or not fully verified.
FlowHelps score
USGS shows 39 cfs with a stable over about 6 hours trend. same-date USGS history (1990-2025, 36 readings) puts the normal middle range around 38 cfs-73 cfs. Flow is inside the same-date normal range, so weather, temperature, and access become the next checks.
SeasonHelps score
Summer: Tricos, caddis, terrestrials, and weed-lane fishing can be useful in early or late windows.
Public alertsHelps score
No active NWS alert was returned for this forecast point.
Read the water
What changes the plan.
Hot Creek is most useful when you slow down. The best plan is a legal access point, a current flow check, a light presentation, and a willingness to watch feeding fish before casting.
Clear normal flow
Use long leaders, tiny flies, and clean downstream or across-stream drifts.
Low and weedy
Target lanes, edges, and sighted fish. Avoid dragging rigs through vegetation.
Stained or high
Use small streamers or visible nymphs only where access is safe and legal.
Geothermal area
Do not enter closed water or closed ground. The danger is real and unrelated to fishing skill.
Field plan
Fish it with intention.
Best flows
Use the flume trend as a context check, not a magic number. Stable clear flow is the best signal for technical dry-fly or emerger fishing; sudden color, weed drag, or a sharp jump in current should push the day toward fewer casts or another creek.
When to skip
Skip the trip when closure boundaries near the geologic site are active in the reach you planned to fish, when wind ruins long-leader control, when snowmelt muddies the lanes, or when crowding forces you to rush drifts in a tiny public section.
Local plan
Start by separating three things before you rig: the closed geologic-site corridor, the private ranch context, and the signed public fishing water. Once the legal access point is settled, watch one weed lane or feeding fish before deciding whether the day should be dries, emergers, or a small indicator rig.
Backup water
If Hot Creek is too windy, crowded, or legally cramped, pivot to the East Walker for a bigger flow-driven tailwater day or to Hat Creek when you still want technical trout water with more room to move.
Hatches & flies
Bring a flexible box.

Confirm the legal public section before fishing; do not trespass on private ranch water.
02
Avoid wading when a bank presentation can work, because fish and habitat are both sensitive.
03
Watch one fish or lane before casting instead of blind-casting the entire creek.
04
Use downstream drifts, reach casts, and slack management to keep leader away from trout.
05
Treat the geologic site as a viewing area with closures, not as a fishing access shortcut.
Access & responsibility
Know the entry. Know the exit.
Verify current CDFW regulations and Inyo National Forest closure notices before fishing. Do not fish in closed Hot Creek Geologic Site areas, and do not enter private water without permission or a valid reservation.
Public water near Hot Creek Hatchery Road
Use signed public areas and confirm boundaries before fishing.
Hot Creek Ranch boundary context
Private ranch access is not the same as public creek access. Follow reservation and property rules.
Hot Creek Geologic Site
A geothermal viewing area with no-fishing and no-entry safety context in closed areas.
Gorge and lower public sections
Can offer public fishing, but access and safety should be confirmed before committing.

Common questions
Before you leave.
Can you fish at the Hot Creek Geologic Site?+
No. Inyo National Forest lists no fishing at the geologic site. Fish only legal public sections and obey closures.
What flow source should I use?+
Use RiverReports and USGS 10265150 at the Hot Creek flume for current flow context.
Should I wade Hot Creek?+
Avoid wading when bank presentations work. The creek is small, clear, and sensitive, and some areas are closed for safety.
What flies work best?+
Bring tiny midges, BWOs, tricos, scuds, caddis, emergers, ants, beetles, and a few small leeches.
