Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Entering Wazee Lake's Bluegill Alley on its west side reveals a structured freshwater quarry designed for diverse training. The lake plunges to 106 m / 350 ft, making it Wisconsin's deepest inland body of water.
An extensive underwater navigation course dominates the site, systematically guiding divers through a purpose-built environment. Numerous submerged training platforms are present, with one often found around 20 meters and another slightly deeper, all placed strategically for skill development. Navigating the course, divers pass a compass rose, signs directing to points of interest, fish cribs, and even whimsical additions like a plastic shark statue or an underwater outhouse.
An underwater road extends from the entry, leading towards the quarry's deeper sections. Recreational divers generally explore depths ranging from 12 m / 39 ft to 25 m / 82 ft, while advanced divers can access a marked point exceeding 30 meters near one of the platforms.
These varied depths and structured features create a versatile site for different certification levels.

Best Time to Dive
Diving conditions at Bluegill Alley are generally favorable, with good to excellent dive scores reported almost year-round. March through December consistently show 'Good' scores (7-8), while February often stands out with an 'Excellent' score of 9. Air temperatures vary significantly throughout the year, from -8°C / 17°F in January to over 21°C / 70°F in July and August. While average water temperatures aren't consistently reported in system data, external accounts suggest bottom temperatures fluctuate from around 5.5°C / 42°F in colder months to 16°C / 61°F, depending on depth and season. Rain averages are lowest in January (1.04 mm) and February (0.62 mm), increasing into spring and summer, with a peak in July (3.80 mm). For optimal visibility and a more comfortable surface interval, visiting during the warmer air temperature months, particularly May through September, is generally recommended. These months align with periods of good dive scores. Divers planning visits outside this period should be prepared for colder air temperatures, especially in winter.

Dive Experience & Conditions
Entering Bluegill Alley typically involves shore diving, providing straightforward access to the lake's features. Divers are greeted by clear freshwater, a quality often noted for practicing deep diving skills here. Below the surface, the environment transitions from a sandy bottom near the entry to an intricate network of underwater attractions. Observed bottom temperatures in dive logs vary considerably, from a chilling 5.5°C / 42°F at greater depths to a more temperate 16°C / 61°F in shallower areas, contingent on season and dive profile. A constructed underwater course serves as a primary draw, guiding divers past training platforms, an underwater road, and various novelties. Visibility, though not consistently reported, is generally good, particularly when divers visit early in the season for clarity. Currents are negligible, characteristic of a quarry environment. Divers will encounter varied depths, from shallower training areas to deeper points, with advanced recreational access extending beyond 30 meters.
Dive Difficulty & Safety Guidelines
When planning a dive at Bluegill Alley, always prioritize conservative practices due to the cold water and varying depths. While no specific hazards were reported in the system data, freshwater quarries like Wazee Lake demand careful buoyancy control. This prevents stirring up the silty bottom, which can quickly reduce visibility for everyone. Water temperatures can drop significantly with depth, with reported bottom temperatures as low as 5.5°C / 42°F at deeper points, necessitating appropriate thermal protection. A dive flag is essential for surface visibility; some accounts mention challenges with snagging lines on submerged trees when deploying flags. Given the extensive underwater navigation course and structures, proficient navigation skills are beneficial. A park entry fee of $10 per vehicle applies for access to the recreation area, which should be factored into planning.
