Lake of the Woods Water Levels

A Privately Owned Lake System — No Federal Management

Lake of the Woods is fundamentally different from every Corps of Engineers or TVA reservoir covered elsewhere on this site. The two lakes are privately owned by the Lake of the Woods Association, Inc. and regulated by LOWA's own Environmental Resources Department rather than by any federal agency. There is no Army Corps guide curve. There is no TVA seasonal drawdown schedule. There is no USACE Nashville or USACE Wilmington district managing pool elevation for flood-control purposes. LOWA manages the lakes for the benefit of its members.

This means the water level experience at Lake of the Woods is fundamentally stable compared to Corps reservoirs. The normal pool is a target that LOWA maintains rather than a seasonal goal that varies with flood management requirements. Docks on the Main Lake are fixed-height structures calibrated to the consistent pool elevation.

Main Lake: Veterans Memorial Dam at 317.5 Feet

The Main Lake covers 500 acres and is impounded by Veterans Memorial Dam — 1,450 feet wide and 60 feet tall, built in 1968. The normal operating pool is 317.5 feet above mean sea level. The lake ranges from 2 feet deep at the upper southwest end where Flat Run feeds the lake to 45 feet deep at the upper end near the dam spillway. The drainage area feeding the Main Lake is 4,557 acres — approximately 7.12 square miles of upland watershed.

LOWA publishes a detailed lake depth contour map on its website showing the depth gradients across the 500 acres. Waterfront lot owners and buyers should review the contour map for any specific parcel, particularly on the Flat Run upper end of the lake where shallow areas make dock placement and boat navigation relevant due diligence items. The upper southwest section consistently shows depths of 5 feet or less. Properties at the Flat Run end have different boating utility than main-body waterfront.

Keaton's Lake: Electric Only at 284.0 Feet

Keaton's Lake — also called Fishing Lake or Small Lake — sits in Section 13 of the LOW community. At 24 acres with an average depth of 7 feet, it is substantially smaller and shallower than the Main Lake. Keaton's Run Dam, 450 feet wide and 34 feet tall and also built in 1968, holds the pool at the normal level of 284.0 feet above sea level. The shallowest portion of the lake is at the confluence of Keaton's Run. LOWA publishes a depth contour map for Keaton's Lake separately from the Main Lake map.

Keaton's Lake operates under fundamentally different rules than the Main Lake: only electric-powered motors are permitted, and the speed limit is no-wake at all times. No gas motors, no personal watercraft, no water skiing. The lake is open to swimming, fishing, canoeing, and kayaking. There is one boat launch area and Cumberland Beach on Cumberland Circle. Properties on Keaton's Lake have a quieter, more fishing-focused character than Main Lake waterfront.

LOWA's Dredging Program

LOWA owns its own dredging equipment and conducts a systematic dredging program on a three-year cycle across both lakes. Dredging removes sand, silt, and organic matter from both lakes at stormwater outfall sites. LOWA maintains a 3-foot buffer from all private property structures during dredging operations and is regulated in how much material it can remove without altering the original lake contours.

Hydrographic surveys were completed in 2003 and 2012 to establish baseline contours. This active sediment management program is one of the reasons the LOWA lakes maintain navigable depth in coves and near-shore areas that accumulate silt on unmanaged lakes. The Environmental Resources Director can be reached at 540-702-2214 for specific questions about dredging schedules, near-shore depth, and water quality monitoring.

Algal Blooms and Water Quality

LOWA maintains an active water quality monitoring program through the Environmental Resources Department. The department tests lake water regularly and posts Beach and Lake Water Status updates at lowa.org when conditions affect swimming or boating. Keaton's Lake has an Algal Bloom Response Protocol updated in March 2025 — the lake's shallower water and slower circulation compared to the Main Lake make it more susceptible to algal bloom conditions in hot, low-wind summer conditions. LOWA posts closure notices through the LOWA website and the TEKControl notification system when blooms are detected.

Triploid grass carp are periodically stocked in both lakes to control aquatic vegetation — a water quality and navigation management tool. The invasive species prevention requirement is explicit: all boats brought into LOW from outside bodies of water must be thoroughly cleaned on the trailer, bilge, motor, and hull exterior before returning to LOW's lakes.
