Official profile first, then live environmental context
Freshness gate: modelled weather older than 3 hours and gauge readings older than 6 hours are treated as unavailable. Timestamps that cannot be parsed or sit more than 15 minutes in the future are rejected, not labelled live.
Inspect source and failure boundaries
Water-quality classifications, sample history and pollution-risk warnings are deliberately not copied from an unverified nearest-point feed. Use the exact Environment Agency profile above.
Do not combine these into a safety score. The official profile, modelled air weather, any nearby gauge and on-site observations answer different questions. A complete response means only that the requested remote sources returned—not that conditions are safe.
Locate the designated monitoring point
The marker is the Environment Agency record coordinate used by this page. It is not an entry point, access instruction or route. Check land-manager information and what is physically present before approaching the water.
For Derwent Water at Crow Park, the marker identifies Derwent Water at Crow Park (ukd1101-45800) at 54.5950, -3.1422. The register names Cumberland Council for this lake record in Keswick. The additional local source reviewed for this page is Lake District National Park activities guide; open it below before turning the record point into a travel plan.

This place check is tied to Derwent Water at Crow Park, identifier ukd1101-45800. The Environment Agency profile is the verification route for the annual classification, sample history and any available pollution-risk warning. Those values are not copied from a nearby-point feed.

What a second, place-specific source changes
Lake District National Park activities guide
- What the source establishes
- The National Park guide permits swimming and several kinds of craft on Derwentwater, notes powered craft and a 10 mph limit, and states there is no island access.
- How it changes this check
- Plan for shared water rather than a swimmer-only lake. Identify the Crow Park exit, keep clear of jetties and craft routes, and check wind across the lake before committing distance.
- What remains unresolved
- Permission to swim is not a statement about today’s wind, temperature, visibility or craft position. The official bathing profile and on-site conditions still need separate review.
Place-specific verification sequence
- 01Open the Crow Park bathing record and keep its annual water-quality evidence distinct from the National Park’s lake-wide activity rules. Neither source reports the other’s status.
- 02Use the Derwentwater activity map to identify jetties, powered-craft context and the no-island-access rule. Draw a shore-parallel route that does not depend on landing on an island.
- 03Observe wind direction across the longest fetch and select an exit still reachable if chop builds. If craft lanes, visibility or a second exit cannot be resolved, shorten the route to shore work only.
Place-specific evidence questions
This file keeps the exact Derwent Water at Crow Park record (ukd1101-45800) separate from same-day observations. Its annual designation evidence is not a current access statement or a safety decision.
- 01What does the current official profile say about classification, samples and warnings?
- 02Could wind direction, fetch or a changing shoreline make the intended exit unsuitable?
Questions to verify—not confirmed local facts
These prompts are deliberately not presented as sourced, current conditions at this place. Resolve each one with the land manager, lifeguard, local authority, current signs or direct observation. Prompt set reviewed 13 August 2026; review date is not evidence that a prompt is true.
Unverified editorial prompt. Do not treat it as a current local warning, access fact or evidence that the condition is present.
