Long Lake (or as it is locally known, Lower Long Lake) is located in Chippewa County, Wisconsin, lying north and east of the city of Bloomer. This area is known as the Chippewa Moraine and was formed by the last Wisconsin glacier. Upon receding, the glacier deposited till to form a terminal moraine through the northern half of the county, consisting of many hills, bogs, swamps, and irregularly-shaped lakes.
Lower Long Lake and the adjoining Herde Lake are the largest local body of water, containing 1,089 acres; depths of up to 101 ft.; and most beautiful with tracts of carefully preserved wooded or wetland natural areas and restored shorelines fronting cottages and homes.
This lake has been used as the route for 29 previous open water swims held every July prior to COVID.
Camping at the park is available: https://reservations.chippewacountywi.gov/parks/camping/morriserickson_campground/

Recreational Water (Lakes, Beaches, and Rivers)
Guidelines for safe swimming are usually based on a geometric mean of multiple samples over a period (e.g., 30 to 60 days) or specific single-sample thresholds set by the EPA. U.S. Environmental Protection Agency (.gov) +1
Safe / Low: Generally ≤ 126 CFU per 100 mL (average) or ≤ 235 CFU per 100 mL for a single sample.
Caution / High Caution: 235 to 1,000 CFU per 100 mL. Water in this range begins to present an elevated risk of gastrointestinal illness.
Unsafe / Critical: >1,000 CFU per 100 mL. Beaches are typically closed or advisory warnings are issued at this level.
