a$.$ Cover based on Snelling soil of which:

i$.85$ acres are good brush

ii$.45$ acres are fair woods

iii. $3$ acres consist of dirt road

b$.$ Time of concentration based on:

i$.$ Overland flow for $80$ feet from Elev. $1108\text{'}$ to Elev. $1106\text{'},$ on wood cover with light underbrush

ii$.$ Shallow concentrated flow for $2800$ feet $($unpaved$)$ to the top of the reservoir
