The dam is separated into two embankment sections, north and south, by a rock knoll, through which the outlet works is located and across a low dike constructed section. Both embankments are rolled impervious fill with a downstream rock shell. Maximum height of the embankment is 49 feet. The total crest length is 2,350 feet.
- A variety of recreations and activities take place at Senecavlle Lake. The U.S. Army Corps of Engineers invites you to tour the dam, which includes the intake structure and flood control facilities. Below the dam is a fish hatchery operated by the Ohio Department of Natural Resources. It is open from 8 AM to 4:30 PM and will accommodate tour groups with advanced reservations. Senecaville Lake has a Haunted Island each mid-October, including a pontoon boat ride to the island. The Muskingum Watershed Conservancy District (MWCD) sponsors it. For more information contact Senecaville Lake Park Office. Also, this is the place to be each Fourth of July for "Fireworks on the Lake."
Fishing and boating are popular pastimes on the lake. A public launching ramp is located near the dam and open year-round. Fishing is permitted at the dam. No fishing below the dam between February 15 and April 15. The horsepower limit at the lake is 299. Boating inquiries can be made by calling Seneca Lake Marina.
Hiking and picnicking is available around Senecaville Lake Dam. A more extensive hiking trail system, a swimming beach, campground and more picnic facilities are available within Seneca Lake Park.
The USACE does not offer hunting, however, the MWCD has several acres of public hunting land around the lake.
There is no visitor center available at this flood control project, however, the MWCD has an activity center within its park. This facility provides day-to-day information on campground activities and current events. The center is staffed April through October or upon request out of season.
The U.S. Army Corps of Engineer's facilities are not handicapped accessible.
Recreation - Senecaville Lake's attractions include boating, camping, fishing, hiking, hunting, lodging, picnicking, dining, water sports and wildlife viewing.
Climate - This state has four distinct seasons and a brilliant fall foliage display in it southern woods during mid October. Winter lasts from December through February with average temperatures near 25 degrees F. Low temperatures dip to single digits, but do not often drop below zero. Northern regions of the state receive average snowfall amounts of 55 inches, while the central and southern regions of the state receive lesser amounts with averages near 30 inches. This difference is caused by lake-affect moisture patterns.
Spring temperatures begin to warm the landscapes of Ohio by mid March and are in full swing by April. Temperatures range from 40 through 70 degrees F through the spring months. This season often brings the most rainfall, before the drying heat of summer. Summer can be extremely hot and humid in the interior of Ohio. Temperatures reach above 90 degrees F frequently through July and August. Cooler fall temperatures don't reach the region until mid to late September. This is a pleasant time to visit as the air is crisp with low humidity levels. Ohio's annual precipitation usually reaches slightly above 50 inches.
The dam project is 1.4 miles upstream of the town of Senecaville and twenty-one miles upstream of Cambridge, Ohio. The lake is approximately six miles east of Interstate 71, exit 37.
