Picture 7. Repairs to right non-overflow section of Lake Roland Dam
The Following Aesthetic Considerations Were Factored into the Dam’s Rehabilitation: Gatehouse restored to its 1861 condition and appearance. Formliners were used to replicate the pattern and texture of original stones used in building dams. To achieve the match, four original stones were removed and used to make molds for fabricating the Formliners. Sidewalks/new observation decks were stamped with slate patterns and chemically stained gray. Replication of the original cast iron handrail end post casting. Complete reconstruction of a stone wall removed for construction access. Construction of an observation deck on top of the south emergency spillway near the gatehouse. Resetting the dam’s original builder’s stone on the new observation deck. Use of a natural rock formation exposed by construction as an energy dissipator for the north emergency spillway. The city was able to make improvements to the park’s entrance road, picnic area below the dam, landscaping, and parking areas. A new environmental center has recently been constructed in the park for children.
Present Condition The Lake Roland Dam is now used for recreational purposes to feed Gwynns Falls where the kayak/canoe races and annual events are held throughout spring and summer seasons. Fishing and boating activities are also predominant on the lake. Lake Roland Park and the newly constructed nature center educates children about the birds and wild animals that frequent the park.

Call for Photos from the Field… Working on a project that has some great visuals but isn’t ready or big enough to warrant a technical paper? We’d love to share those visuals with our readers. Please submit a high-resolution photo (at least 300dpi at 3.657” [1100 pixels] wide for a onecolumn photo. If you’re taking a photo with a phone, email us your highest quality or “original.” A larger file— 300dpi at 7.5”—is always better as it gives us more options. You could even make the cover! In addition to the photo, please include a brief caption describing the site and name of the project. And don’t forget to include a credit for the photographer. We can’t guarantee you will get into an issue as photos will be published “as space allows.”
