Total Maximum Daily Load (TMDL) Reports
When pollutants impair the use of water a study is required
to determine how to reduce them and restore water quality. This study is called
a Total Maximum Daily Load (TMDL). A TMDL establishes the maximum amount of a
pollutant allowed in the water while maintaining all of its designated
beneficial uses. Two Reports related to TMDLs have been developed for the Provo River Watershed. They are the 1999 Upper Provo River Water Quality Management Plan and the Deer Creek Reservoir Draining TMDL Report.

Deer Creek TMDL
In 2002 a comprehensive study to develop a TMDL for Deer Creek Reservoir was initiated. This study included not only water quality analysis, but also computer modeling of Deer Creek Reservoir to test various water quality input scenarios. Additionally, fishery studies were conducted to also identify the health of the reservoir. A list of various TMDL targets was developed and is shown at right. This also shows whether the targets have been met for recent years.
Upper Provo River Water Quality Management Plan
A Water Quality Management Plan was developed for the Provo River, and
Deer Creek and Jordanelle Reservoirs in 1984.
In 1999 many of the recommendations from the 1984 plan had been
implemented, however, the loadings and concentrations of various pollution
indicators still remained high. In
response to this disparity, a review of the management plan was
commissioned. Also, at the same time,
the EPA had initiated requirements for States to develop calculations of Total
Maximum Daily Load (TMDL) values for waters not meeting beneficial uses. This report provided TMDL calculations for
phosphorus for five stream segments on the Provo River as well as three other
stream segments on Snake Creek, Daniels Creek and Main Creek. Also, a TMDL was calculated for one point
source, the Kamas Fish Hatchery.
The recommendations from this report include:
Optimize the SLOW tower on Jordanelle Reservoir for water quality
Research the influence that groundwater quality has on Deer Creek Reservoir
Develop a plan to control stormwater runoff in Heber Valley
No Municipal Phosphorus Discharge
Require new private and pubic developments to be subject to regulations for control of runoff, pollutant control, and plan review
Amend the Wasatch County and Summit County Zoning Ordinances to prohibit runoff or discharges from AFOs and CAFOs
Require developers of Mayflower Mountain Resort to stabilize the Mayflower tailings ponds.
Mount a public education campaign to educate farmers and ranchers about controling over application of water and runoff from agricultural lands
Continue the work and funding of the Deer Creek/Jordanelle Technical Team.
Consider other restoration techniques/projects or phosphorus reduction programs.
