'Dissolved Oxygen is reported /or the Deer Trail Ditch only.
Required by current permit.
Baseline Information for Point Deer-up is denvetl Irom events beginning on 8/74/1995 Nrough 3/30H 997, a period of -T7 monttu. Point infiuenceo by mining on 3/30/1997.
The upper end or the Deer Trail Ditch is monitored at the heatl9ate loratetl on Hubbard Creek. This monitoring point is fitted wah a 2' Parshall Flume.
