Item #: SCP-8362
Object Class: Euclid
Special Containment Procedures: SCP-8362 has a 5 kilometer exclusion zone that is to be maintained around the lake at all times, with armed, on-site security personnel stationed at Provisional Site-60. All unauthorized access is prohibited. Civilians found within the exclusion zone are to be detained, interrogated, and administered Class-B amnestics prior to release.
Personnel assigned to SCP-8362 are subject to mandatory weekly psychological evaluations. Under no circumstances are personnel to enter SCP-8362's waters without Level 4 authorization. Following Addendum, Incident-07, all expeditions into the lake have been suspended indefinitely, and future exploration requires O5 Command approval.
Submersible drones are to be deployed for exploration, while human interaction is limited to surface-level observation only. Direct human contact with SCP-8362 has been deemed too dangerous.
Description: SCP-8362 is an anomalous lake located in Dunmanway, Ireland, approximately 1.5 kilometers in diameter (0.9 miles). It exhibits a depth that has not been fully measured. All sonar and submersible attempts to gauge its depth are interrupted beyond 2 kilometers due to unknown interference. The exact nature of this interference remains inexplainable, though speculation suggests a cognitohazardous or memetic effect tied to the lake's anomalous properties is its reason.
SCP-8362 at night.
SCP-8362 manifests a potent cognitohazardous effect upon direct contact with its waters. Subjects immersed in the lake experience an overpowering sense of calm and relaxation, followed by a sharp decline in cognitive function. Within 10-15 minutes, subjects fall into a comatose state and are inexorably drawn deeper into SCP-8362. No subjects who have descended beyond 2 kilometers have been recovered, and attempts to recover them have led to [REDACTED].
The entity responsible for these effects, designated SCP-8362-A, is believed to reside at extreme depths. SCP-8362-A is hypothesized to possess telepathic capabilities, influencing subjects more aggressively the deeper they go. Subjects report auditory hallucinations in the form of a "lullaby" or "soothing voice," urging them to sleep and “join it in the silence.” While no direct visual contact with SCP-8362-A has been made, recurring dreams of a colossal, aquatic entity resembling a massive maw have been reported. Descriptions of SCP-8362-A from the few surviving hallucinations have been [REDACTED], with further specifics on its form and influence [DATA EXPUNGED].
Addendum, Incident-8362-01, Initial Discovery: SCP-8362 came to the Foundation's attention after a series of disappearances over a two-decade period. Local legends attributed these incidents to a "lake spirit," though initial investigations dismissed such claims. It wasn't until Incident-8362-01, when a Foundation drone was sent into the depths, that SCP-8362's cognitohazardous properties were confirmed. The drone’s signal was lost at approximately 2 kilometers, substantiated the theory of an unknown force present at these depths.
Addendum, Incident-8362-04, Expedition-01:
Foreword: On 07/14/03, Expedition-01 was authorized to investigateSCP-8362. Five D-Class personnel (D-34728, D-30485, D-32847, D-31394, and D-30284) were equipped with specialized diving suits designed to withstand pressure and cognitohazardous interference, as well as cameras. The dive commenced at 03:37 GMT.
<BEGIN LOG>
03:37 GMT - DIVE INITIATED.
All vitals stable, and the communication feed from all five divers is clear. Surface tension appears normal.
03:45 GMT - 100 meters.
Visibility drops significantly, despite high-powered lamps. No abnormalities detected. Divers report a slight increase in pressure but nothing outside of expected parameters. Water temperature recorded at a steady 4°C.
03:50 GMT - 200 meters.
D-30485 reports an unexplained sense of fatigue. D-32847 confirms similar drowsiness. No other divers report symptoms at this depth, but all personnel note a subtle shift in the water’s clarity.
03:55 GMT - 300 meters.
All divers are now exhibiting signs of extreme tranquility. Breathing patterns have slowed, and heart rates drop by an average of 20%. D-34728's voice is slurred over comms, muttering about hearing a faint lullaby. D-30485 starts humming along, though he denies hearing any sounds when questioned.
04:02 GMT - 400 meters.
D-30485’s camera feed cuts out abruptly. His vitals spike once before flatlining. The remaining divers show signs of catatonia.
04:07 GMT - 499 meters.
Comms cut off entirely. All vitals flatline in rapid succession. The expedition was aborted.
<END LOG>
Closing Statement: At 499 meters, all divers' vitals flatlined simultaneously, and the dive was deemed a failure. Attempts to recover the bodies were initiated shortly after, with a recovery crew dispatched to the surface of SCP-8362. The team, descending to 287 meters, reported similar feelings of drowsiness and tranquility, leading to the immediate termination of the recovery mission.
Three pieces of wrecked gear were found floating in SCP-8362, identified as belonging to D-30485, D-32847, and D-31394. No bodies were recovered, and all attempts to retrieve the remaining equipment were unsuccessful. Analysis of the damaged gear showed evidence of strange scratches, which is currently under review.
Visual data from the remaining cameras is highly distorted, though frames captured at 500 meters suggest the presence of SCP-8362-A.
Further expeditions are pending evaluation by the Ethics Committee,, with proposals to send highly trained Foundation divers and submersibles outfitted with reinforced cognitohazard shielding. Exploration beyond 499 meter* is deemed highly dangerous and will rely on submersibles if human interaction remains untenable.
Addendum, Incident 8362-07, Expedition-02:
Foreword: Following thorough evaluation by the Ethics Committee and approval from the Overseer Council, Expedition-02 was authorized to resume exploration of SCP-8362's depths, with a focus on determining the limits of SCP-8362-A’s influence. Three specialists, Elena Lane, Samuel Gray, and Oliver Hays, were selected for the mission. All were transported from Site-19 to Provisional Site-60, where they underwent intensive one-week training in handling extreme pressure, cognitohazard exposure, and resisting sleep-inducing effects.
On 10/03/03, the expedition was launched with the team equipped with cutting-edge submersible suits and accompanied by three autonomous drones. A specialized pulley system was installed on the surface, designed for immediate extraction in the event of a vital drop. This fail-safe was intended to protect divers from becoming lost below 500 meters.
<BEGIN LOG>
03:12 GMT - DIVE INITIATED.
All vitals are stable. Visibility is clear, and communications remain intact.
03:22 GMT - 100 meters.
Divers report no anomalies. Water temperature holding steady. Lane comments on the unsettling quiet, noting that even the usual sounds of underwater currents seem muted. All personnel maintain normal breathing rates, though the first sonar returns from the drones show distorted shapes at the edge of detection.
03:30 GMT - 200 meters.
Samuel Gray reports sudden tranquility and muscle fatigue , specifically a "numbness" in his limbs. The others confirm similar sensations, though there are no external signs of impairment. Breathing and heart rates are lowering. The team is reminded of imminent danger and to remain focused.
03:37 GMT - 300 meters.
Lane and Hays experience what they describe as "weightlessness." Communication with the submersibles becomes erratic, cutting in and out. Audio feeds intermittently pick up what sounds like low, rhythmic humming. Gray mutters something indecipherable, though his vitals remain within acceptable parameters.
03:45 GMT - 400 meters.
All vital signs begin a slow, downward trend. The divers report an overwhelming sense of peace. The submersibles send back fragmented images of shadowy shapes moving along the periphery, but no concrete readings. The water darkens significantly.
03:52 GMT - 500 meters.
Gray’s vitals drop rapidly. The pulley system is immediately activated, and he was being pulled upwards. His camera feed captures what looks like a massive, indistinct form far below, though it fades into static before any details can be discerned. Gray’s extraction proceeds without further incident, though his respiration remains shallow.
03:58 GMT - 589 meters.
Two submersibles malfunction simultaneously. Their video feeds freeze on blurry, undulating shadows before going dark. Lane and Hays are instructed to pause their descent and attempt diagnostics on the drones, but both divers report intense feelings of dissociation.
04:03 GMT - 644 meters.
Lane and Hays ignore instructions to halt and continue their descent, describing an overpowering urge to "go deeper." The pull from below becomes noticeable on their equipment, and both divers report pressure fluctuations far beyond normal readings. Their vitals spike without explanation.
04:07 GMT - [UNKNOWN DEPTH].
The pulley system engages, but the mechanism struggles against a force pulling both divers downward. Despite maximum extraction efforts, the system falters. A strange force dragged Lane and Hays into the abyss. Hays began to speaking in an alien cadence, repeating fragments about "lullabies" and joining "it in the silence." Lane’s camera briefly captures a faint glimpse of a massive maw before her feed cuts to static.
04:11 GMT - [UNKNOWN DEPTH].
Both divers' vitals flatline. Their cameras disengage, and the remaining submersible footage shows Lane and Hays’ bodies sinking deeper, pulled beyond the range of any retrieval effort. The maw fills the final frames before all visual and auditory data is lost.
<END LOG>
Closing Statement:
The bodies of Elena Lane and Samuel Gray were never recovered. No wreckage or damaged equipment was retrieved, and the malfunctioned submersibles were unrecoverable. The final telemetry from their dive suggests the presence of an entity at depths beyond human reach, one capable of exerting significant gravitational force on its surroundings.
Further expeditions into SCP-8362 have been permanently disapproved by the O5 Council. While research continues using drones and sonar probes, direct human interaction with SCP-8362 is now prohibited. Future research will rely exclusively on long-range sonar probes and advanced drone technology, pending further review.
