Lake Tarsney, founded in 1927 by the Sotham Brothers Real Estate Company, was envisioned as a rural recreational haven for affluent individuals from Kansas City, Missouri, and the surrounding areas. Named in honor of the late John Charles Tarsney, a former United States Congressman and close friend of the Sotham family, the lake had high hopes of becoming a sought-after retreat. However, the development faced numerous challenges that prevented it from reaching its full potential.
Unlike its neighboring lakes, Lake Tarsney boasted a unique near-rectangular shape, occupying the lowest point on the western edge of the development. The dam and spillway acted as the lake's northern boundary, providing the sole entrance to the homes on the eastern side. The waterfront on the eastern boundary was limited due to Beach Drive running closely along the lake, leaving only two homes with direct waterfront access. A cove and inlet adorned the southern end, though no homes were built there, and access was limited to a derelict gravel road. The western edge, near Tarsney Road, offered ample waterfront development with ten lakefront homes enjoying spacious yards. However, most homes were located on the eastern hillside, obscured by dense trees, which blocked their views of the beautiful lake. The lack of essential amenities, like a well-maintained boat ramp, further dampened the lake's appeal, leaving many lots on the eastern side vacant to this day.
The dam and spillway posed additional challenges, some of which continue to affect Lake Tarsney's residents today. Originally, the lake had a limited-service spillway in the form of a box culvert on the western side of the dam. However, it proved inadequate during heavy rains and flooding, leading to engineering modifications. In 1965, a new spillway was constructed on the eastern edge of the dam to address the issue. Despite these efforts, structural problems persisted, with an excessive downstream slope on the northern side of the bridge and erosion on the outlet channel of the new spillway.
The Sotham Brothers Real Estate Company's reluctance to maintain the lake and finance improvements ultimately led to the city council purchasing Lake Tarsney for a meager sum in 1976. Emergency measures were later taken to lower the water level when an Army Corps of Engineers inspection in April 1978 revealed the dam's risk of imminent failure due to high-water levels. Though a subsequent project in 2021 brought some improvement, such as a new triple-cell concrete-reinforced box culvert spillway, unresolved issues persist, affecting property values and discouraging further development around the lake.
To revitalize the area and attract renewed interest, it is crucial to address the remaining dam issues and implement additional improvements. Proper planning, community engagement, and ongoing maintenance are essential to fulfill the original vision of Lake Tarsney as a desirable recreational retreat for residents of Kansas City and its surrounding areas.
