# Minimum Threshold Volume Storage Recorder

## General Description

Record whether a *Storage* node falls below a particular volume threshold during a simulation.

This recorder will return a value of *1.0* for scenarios where the volume *Storage* is less than or equal to the threshold at any time-step during the simulation. Otherwise it will return zero. [API Reference](https://pywr.github.io/pywr-docs/master/api/generated/pywr.recorders.MinimumThresholdVolumeStorageRecorder.html)
