WQPredict

Modeled nutrient concentrations and loads for hundreds of streams—bridging gaps between sparse concentration measurements and actionable load data

What is WQPredict

What are the elements of the WQPredict dataset?

Daily Concentrations

Measured concentration data (mg/L) are too sparse to reliably estimate nutrient loads. WQPredict models daily concentrations to fill gaps between measurements.

Nutrient Loads

Nutrient load is the mass of nitrogen or phosphorus being exported from the watershed. It is estimated by combining nutrient concentrations with streamflow data.

Spatial Coverage

WQPredict includes monitoring sites across the US and Canada. The sites represent a range of watershed sizes, land uses, and hydroclimatic regions.

Data is available for multiple solutes, including nitrate, total phosphorus, total nitrogen, and dissolved phosphorus.
