developer Ralph Street in 1912. He put together the initial funding and began building roads, railroads, and infrastructure necessary to begin construction of a dam, with a plan to impound a much smaller lake. In the mid-1920s, Street's funding dried up, and he abandoned the effort.
The lake was created by the construction of the 2,543-foot-long (775 m)

While some sources indicate that more than 20 towns, villages, and settlements were permanently flooded to create the lake, the actual number was closer to eight. Several other settlements had been previously abandoned, were relocated to make way for the lake, or were on high enough ground that the creation of the lake did not affect them.

The Osage River feeds into the lake at the most western arm of the lake east of Warsaw, Missouri. Many smaller tributaries also drain into the lake, creating numerous small coves and indentations in its shore.[ As a result, the lake has around of shoreline.]
Cities and towns
Numerous settlements are located near or on the Lake of the Ozarks. With a population of 4,570, the largest city is Osage Beach, which sits where the lake's southeastern arm joins the main channel. The second largest is the city of Camdenton, located a few miles east of the southwestern arm. Lake Ozark lies immediately north of Osage Beach and just south of Bagnell Dam. Other, smaller communities along or near the lake include (from east to west): Kaiser

Infrastructure

A large number of bridges had been constructed for efficient crossing of the lake. The Niangua Route 5 Bridge, built in 1936, was replaced by a girder bridge in 2003. The Niangua Arm US 54

Bridge, built in 1931, was replaced by a girder bridge in 1999.
Hurricane Deck Bridge
The Hurricane Deck Bridge is a delta-frame bridge located in the west side of Lake of the Ozarks. Stretching over long and wide, the bridge was established to connect Laurie with Camdenton. The bridge was originally constructed in 1934 as a truss-arch bridge, but this bridge was replaced in 2013. The first bridge's structure was similar to the structure of the I-35W Mississippi River bridge, which had collapsed six years before the bridge was destroyed. After the replacement opened in 2013, the original bridge was destroyed.
Grand Glaize Bridge
Originally built in 1930, the Grand Glaize Bridge crosses the Grand Glaize Arm of the lake in Osage Beach. It carries U.S. Route 54

and connects Osage Beach to Camdenton. Originally, one girder bridge carried both directions of traffic; a second girder bridge was constructed in 1984, enabling traffic to pass over the lake in both directions using separate bridges. It has undergone a significant number of improvements since its original construction, and now supports three lanes of traffic in both directions.
Bagnell Dam
Originally constructed in 1931, Bagnell Dam is the only major dam supporting Lake of the Ozarks. Located in Miller County near Camden County, the dam is 2,543 ft (775 m) long and 148 ft (48 m) tall. The dam was originally constructed by the Union Electric Company (now Ameren

) to provide hydroelectric power to the nearby Osage Powerplant (located near the base of the dam) and support two-way traffic on a narrow highway above the dam (Bagnell Dam Boulevard). Since its original construction, the dam has undergone a number of significant infrastructure upgrades throughout the 2010s. The dam has 12 floodgates, which fully open when the lake floods. In 2019, the floodgates were open due to the Lake of the Ozarks being hit by flooding.
Lake of the Ozarks Community Bridge
The Lake of the Ozarks Community Bridge is a continuous truss bridge in Lake Ozark. The bridge is over long and wide. Built in 1998, it is one of the newest bridges in the Lake of the Ozarks area, primarily built to connect the east (towards Lake Ozark and Osage Beach) and west sides (towards Sunrise Beach and Camdenton) of Lake of the Ozarks. The bridge was the only toll bridge in the Lake of the Ozarks area and only toll bridge in Missouri with a toll that varies between seasons. The bridge tolls stopped on April 30, 2024. The bridge was originally expected to be toll-free by 2026.

Missouri Route 134 runs southeast from U.S. 54 north of Osage Beach to its southern terminus in Lake of the Ozarks State Park. Route 42 connects to Route 134 and US 54 in Osage Beach. Route 242 connects US 54 to near Village of Four Seasons. In addition, a network of supplemental state routes provides access to various points along the lake shore.

and water levels of the lake. All land surrounding the lake that is within the project boundary defined by the FERC is under the company's jurisdiction. Any improvements to the shoreline, including docks, seawalls, and other structures, require permission from Ameren Missouri prior to construction.
Tourism and recreation
During the process of land acquisition for the lake during the 1920s, of land were set aside for a national park along the Grand Glaize Arm of the lake. In 1946, this land was acquired by the State of Missouri for Lake of the Ozarks State Park, the largest state park in Missouri. Another state park on the shores of the lake is Ha Ha Tonka State Park on the Niangua Arm of the lake.
