Goals/Objectives
- determine the effects of the restoration project on water quality
- gain a better understanding for the chemical and physical dynamics of project area in the watershed
- establish two water quality monitoring stations that are representative of the area and the restoration project
- accurately determine nutrient and sediment loading at the monitoring stations

•River has no mercy on costly instruments.
•Requires daily DISCHARGE data, therefore continuous STAGE data.
•Requires daily sample concentrations.
•No USGS Station
•Flashy River, short and steep hydrograph.

Objective: Determine river’s discharge at as many different river stages as possible to generate a correlation between river stage and river discharge.

Sample Concentrations
•Analyses were determined from three types of samples; grab samples, composite samples and storm samples.
Outliers for grab and composite samples were defined and then removed from the data set (3*STDEV).

Loading Estimations
•Discharge was estimated for the project period.
Loading was calculated from all samples by numeric integration method.
