Historical Deer Creek Reservoir TSI and Provo River Average Flow

The Carlson Trophic State Index (TSI) has been used by the State of Utah to be useed by the State of Utah to rank and compare the trophic status of lakes and reservoirs within the state. This index used chlorophyll A or secchi depth data from May to September. This figure compares the calculated TSI valve that have been calculated since 1993.

Historical Phosphorus Loading Below Deer Creek Reservoir

The data from steam samples that were collected are used with flow data to calculate river loadings of thre constituents: TSS, TP, and DTP. This figure indicates the historical phosphorous loading for the 2005 water year. The table below indicates the loads for TP, DTP and TSS and the average flow in comparison to the previous six years.
