inflatable rubber dam

Here's a juicy tidbit from the white water proposal site:

"There is the possibility of a rubber dam mentioned in the report. What are the benefits? Technology exists to increase the height of existing weir structures by attaching an inflatable rubber structure. Raising the height of the weir by nearly a metre translates into a substantial increase in capacity of power generation. Increasing the head height would also benefit the water part design.
Use of an inflatable rubber dam would create great bank stability upstream as water level fluctuations can be controlled and maintained by increasing or decreasing the dam height in unison with changes in river flow."

An inflatable rubber dam? Wow, that sounds really attractive. Could it perhaps be bright pink or orange, something eye catching? All the green around the riverbank in the summer gets so dull--green trees, grass, the glassy green of the river water. And I bet you could get a corporate sponsor for something like that--Trojan, perhaps?
