| Commercially available structures offer either stacked flashboard risers or floats to adjust this water level. |
| Collecting activities were seriously curtailed in the 1930s when two flashboards, or risers, were added to the top of the extant concrete dam. |

| Early risers were treated to a glorious sunrise at the traditional dawn chorus. |
| The risers need to be forklifted off of their wheeled carts and the students must return the carts to Event Storage. |
