Read Me for Inflow Data:

These files contain data recording flow through a culvert into an infiltration
basin. 

Each file is named with the corresponding water year (WY). A water year runs
from 1 October - 30 September; for example water year 2012 (WY12) is 
1 October 2011 - 30 September 2012.

Each file has four columns of data. The first column indicates the water day 
(1 through 365), where water day 1 = October 1. The second column indicates the 
average stage recorded in the culvert on that water day, in meters. The third
column indicates the total volume of water that flowed through the culvert
into the infiltration basin on that water day, in cubic meters. The daily
total volume of flow was calculated using the Manning Equation. The fourth column
is the cumulative flow volume for the water year to date.
