odeqtmdl

The odeqtmdl R package includes data tables of Oregon TMDL information and a set of functions that assist in assessment of water quality data against select TMDL targets. The TMDL information is still being assembled and is undergoing review. Some information may not be accurate or complete. TMDLs developed by tribal governments are not included at this time. See each relevant TMDL document for the official record.

Data Table Usage

A listing of TMDL actions in Oregon.

odeqtmdl::tmdl_actions

The NHD reaches where TMDLs have been developed. Note this table is large and may take a minute to load.

odeqtmdl::tmdl_reaches()

The Oregon assessment units and unique stream name (GNIS) watershed assessment units where TMDLs have been developed.

odeqtmdl::tmdl_au
odeqtmdl::tmdl_au_gnis

Summary of all unique 303(d) water quality limited parameter and pollutant pair combinations for each TMDL action.

odeqtmdl::tmdl_parameters

The beneficial uses impacted by the water quality parameter addressed by the TMDL

odeqtmdl::TMDL_ben_use

Partial inventory of TMDL targets. The table includes TMDL target value, target unit, statistical base, season start/end, and the geo_id. A geo ID is a unique ID used to identify the applicable NHD reaches and Oregon Assessment Unit where the target applies.

odeqtmdl::tmdl_targets

Inventory and narrative description of unique TMDL geo IDs.

odeqtmdl::tmdl_geo_ids

Lookup table of DEQ and EPA ATTAINS water quality parameter names and IDs.
