pywrdrb.pre.ObservationalDataRetriever#

class pywrdrb.pre.ObservationalDataRetriever(start_date='1945-01-01', end_date=None)#

A retriever class for observational reservoir data using the DataPreprocessor interface.

This class collects inflow, release, and elevation data from USGS NWIS, processes and saves raw time series, and converts elevation to storage using predefined storage curves.

__init__(start_date='1945-01-01', end_date=None)#

Initialize an ObservationalDataRetriever instance.

Parameters:

  • start_date (str) – Start date for data retrieval, typically set to the model start date (e.g., ‘1980-01-01’).

  • end_date (str, optional) – End date for data retrieval, defaults to today’s date if not provided.
