3. PTMApp Goals
▪ Plan and implement prioritized practices
▪ Target projects to improve water quality in specific lakes and
rivers
▪ Estimate effectiveness of one or many practices in combination
at multiple spatial scales (field, small watershed, large
watershed)
▪ Change how decisions can be made about improving water
quality – NO MORE RANDOM ACTS OF CONSERVATION!

6. PTMApp Inputs
WHAT IS PTMApp?

7. ▪ Typically, priority resource points reflect some area of interest (e.g.
lake inlet/outlet, river reach at risk, gage/monitoring station…)
▪ Locations - in addition to the catchment outlets - within the
watershed where sediment, total nitrogen, and total phosphorous
are “routed”.
▪ Locations where information about the benefits and costs of
conservation/best management practices are generated.

12. EVALUATE: Practice Feasibility
EXAMPLE PRODUCTS
AND USES
• Depends on several factors:
❖ Size of contributing drainage area
❖ Land slope
❖ Flow regime
❖ Land use (e.g. cultivated land)
❖ Societal factors (e.g. landowner willingness)
• NRCS design standards used
• Six BMP treatment groups

19. Some FinalThoughts
No tool is perfect. Define the problem, use the right tool.
PTMApp is for Water Quality Planning

20. Limitations
• PTMApp – Desktop ProcessingTimes
• Spatial resolution of Land Use / LandCover
Data
• Needs more validation forTP/TN loss in
range of landscapes
• Ignores existing practices unless “entered”
• Lacks near channel sediment
• No hydrological routing
