THE ALUM CREEK STORY

A creek reshaped by flood control and a major central Ohio reservoir

Alum Creek begins as a modest central Ohio stream, passes through one of the region’s largest recreation lakes, then returns to a winding urban creek before meeting Big Walnut Creek at Three Creeks.

1962
Federal authorization
The Alum Creek Lake project was authorized for flood control along with recreation, fish and wildlife, water quality and water-supply purposes.
1974
Alum Creek Dam is completed
Construction created the modern Alum Creek Lake, permanently changing the creek corridor north of Columbus.
Modern era
A major recreation lake
The reservoir now provides thousands of acres of water for boating and fishing while the dam continues its flood-risk and water-management roles.
Today
The creek returns below the dam
Below the lake, Alum Creek flows through Westerville and Columbus alongside greenways and parks before reaching the Three Creeks confluence.

Where the river changes

FISHING AREA
Northern Alum Creek Lake
No-wake coves, woody cover and quieter shoreline create a different fishing environment from the open southern lake.
FISHING AREA
Southern Alum Creek Lake
Broader open water supports boat fishing for bass, saugeye, walleye, muskie, crappie and other reservoir species.
FISHING AREA
Below Alum Creek Dam
The creek returns to flowing water below the reservoir, creating tailwater and urban-stream fishing opportunities.
FISHING AREA
Three Creeks
The lower creek reaches its confluence with Big Walnut and Blacklick creeks within a large public park corridor.
Before you fish
  • Lake fishing conditions change substantially with season, depth and water temperature.
  • Boat and shoreline fishing are both available at Alum Creek Lake.
  • Check current Ohio fishing regulations before fishing.
BOATING & PADDLING

On the water

Alum Creek Lake is a major central Ohio boating destination, while quieter coves and the free-flowing creek provide paddling opportunities on a very different scale.

Southern Alum Creek Lake
The broad southern lake allows unlimited-horsepower boating and supports the reservoir’s busiest recreation.

Northern Alum Creek Lake
The northern lake is no-wake, with tree-lined shores, shale cliffs, coves and quieter paddling water.
