Diving atMud Spring (United States)
Descending into Mud Spring begins within a sizable head pool, approximately 400 ft (122 m) in diameter. From this entry point, divers can transition into the main spring basin, which features an irregular slope on its north, east, and south sides. The primary descent often follows the west wall, which plunges vertically to a significant depth, drawing divers deeper into the spring's unique aquatic environment.
Current morning readings from Mud Spring indicate an air temperature of 23.3°C. Surface wave heights are averaging around 0.32m at this time. These local measurements provide a baseline for your daily dive planning.

Dive Site Overview
Mud Spring's considerable basin forms its primary topographic feature, presenting as an elongated depression running north-south. Near the expansive head pool's southwest side, approximately 15 ft (4.6 m) east of a dock, lies the spring's main vent area.
The basin's west wall drops sharply, reaching a maximum depth of 185 ft (56 m). A distinctive 200 ft (61 m) wide run flows eastward from the main pool, signaling the spring's continuous outflow into the Mud River. Throughout much of the spring, a brown, flaky material covers the bottom substrate; this is likely algal and contributes to the spring's namesake appearance.
Known historically as both Sulfur Spring and Mud River Spring, it currently serves as an important fishing and boat launching site, indicating its accessibility and local significance.
Best Time to Dive
While year-round diving is feasible at Mud Spring, distinct seasonal differences in air temperature impact the surface experience. The warmer months, particularly May through September, consistently show excellent dive scores, with average air temperatures ranging from 24.9°C (76.8°F) to 27.7°C (81.9°F). These periods also tend to have lower wind speeds, contributing to a more comfortable surface environment. Conversely, cooler air temperatures, such as 13.4°C (56.2°F) in January or 15.5°C (60°F) in February, make spring and fall months good options for those who prefer moderate weather, though rain amounts are generally low across all months, fluctuating from 1.3 mm (0.05 in) to 5.9 mm (0.23 in).

Dive Experience & Conditions
Strong currents distinctly define the dive experience within Mud Spring. Divers frequently report a consistent horizontal westward current, reaching approximately 3 miles per hour (4.8 km/h) at a depth of 50 ft (15 m). Such a robust flow necessitates good buoyancy control and streamlined gear, particularly when navigating deeper sections. Spring discharge is notably tidally affected; measured flow rates vary between 83.1 ft³/s (2.35 m³/s) and 128 ft³/s (3.62 m³/s) on changing tides. This tidal influence means conditions can shift, requiring divers to remain adaptable. Historical data from December 1960 reported water temperature for the spring at 20.5°C (69°F). Visibility within the spring can be impacted by the prevalent brown, flaky material covering the bottom. This likely algal matter can be stirred up if not approached carefully, potentially reducing clarity throughout the water column. Its presence contributes directly to the spring's distinctive name and requires divers to maintain good trim.
Dive Difficulty & Safety Guidelines
Navigating Mud Spring requires a clear understanding of its inherent challenges, primarily the strong subsurface currents. A reported 3-mile-per-hour (4.8 km/h) westward current at 50 ft (15 m) demands advanced diving skills and appropriate physical conditioning to prevent divers from being swept away or tiring prematurely. Given the deep maximum depth of 185 ft (56 m) along its vertical west wall, divers should be certified and proficient in deep diving techniques. Maintaining excellent buoyancy control is crucial to avoid disturbing the bottom's flaky, algal material, which can significantly reduce visibility for all divers. Always dive with a reliable buddy and carry appropriate safety equipment, including a dive light, especially when exploring deeper or more obscured sections.

Frequently Asked Questions
What is the maximum depth at Mud Spring?
Mud Spring's main basin features a west wall that descends vertically to a maximum depth of 185 ft (56 m). Shallower areas are also accessible, particularly in the head pool.
Are there strong currents at Mud Spring?
Yes, Mud Spring is known for its active currents. Divers commonly encounter a horizontal westward current of approximately 3 miles per hour (4.8 km/h) at a depth of 50 ft (15 m). The spring's discharge is also tidally affected.
What is the water temperature like?
Historical data from December 1960 reported the water temperature at Mud Spring to be 20.5°C (69°F). While this is an older record, it provides an indication of the spring's generally consistent temperature.
Why is it called 'Mud Spring'?
The spring is named for the brown, flaky material, likely algal, that covers its bottom. This substrate can give the water a 'muddy' appearance, especially if stirred up.
What is the best time of year to dive here?
Diving is feasible year-round. However, May through September offer the warmest average air temperatures, ranging from 24.9°C (76.8°F) to 27.7°C (81.9°F), and generally excellent dive conditions.
Is Mud Spring suitable for all divers?
Due to the strong currents and the maximum depth of 185 ft (56 m), Mud Spring is generally recommended for experienced divers with advanced certifications, particularly those proficient in deep diving and navigating strong flows.
