In the above map, the yellow area is the City of Rockwood, the red stars are West Roane VFD stations, the red dashed line is the West Roane VFD boundary (the same as the "District 5" boundary), and in the zoomed version the little red dots are hydrants.

Water is our most abundant and least expensive fire fighting agent. When fire companies arrive at a working fire, they need to be able to quickly determine which tactics they should employ and how best to supply themselves with water. There are several vital bits of information that we need.
Primarily, we need to know how much water is available from the closest hydrant so that we may select the appropriate size hose lines for the size and complexity of the fire, but not select lines that would exceed the capacity of the hydrant and thus be ineffective. This information is known as available flow.
