Eastwood Lake in Dayton, Ohio, has an average depth of 8 feet and a maximum depth of 21 feet.

Eastwood Lake is a man-made reservoir covering 185 acres with varying depths. Its average depth is 8 feet, while the deepest point reaches 21 feet near the dam. The lake supports fishing, boating, and recreation, with depth influencing water temperature, fish habitats, and safety for swimmers.

Key Depth Details

  • Average depth: 8 feet (2.4 meters)
  • Maximum depth: 21 feet (6.4 meters) near the dam
  • Shallow areas: 3-5 feet (0.9-1.5 meters) near shores and coves
  • Thermocline: Typically forms at 6-10 feet in summer, affecting fish behavior

How Depth Affects Activities

Fishing

  • Shallow zones (3-8 ft): Ideal for panfish (bluegill, crappie) and bass spawning
  • Mid-depth (8-15 ft): Best for walleye, catfish, and hybrid striped bass
  • Deep zones (15-21 ft): Holds larger predatory fish in summer/fall

Boating & Safety

  • Motorboats should avoid areas <5 feet to prevent propeller damage.
  • Kayaks/canoes can navigate shallow coves but risk grounding in drought conditions.
  • Swimming is discouraged in areas over 10 feet due to sudden drop-offs.

Seasonal Depth Changes

  • Spring: Water levels rise 1-2 feet from rainfall/snowmelt; depths increase temporarily.
  • Summer: Evaporation may lower levels by 6-12 inches, exposing shallow areas.
  • Fall/Winter: Stable depths; dam releases can reduce levels by ~1 foot for maintenance.

How to Check Current Depths

  1. Use a fish finder or depth sounder for real-time measurements.
  2. Consult local fishing reports or lake management updates for recent surveys.
  3. Observe buoys/markers (often placed at 5-foot and 10-foot drop-offs).
  4. Check USGS water data for historical depth trends (affected by droughts/flooding).
