Release Notes

Breaking Changes

Drop support for Python 3.6 since many of the dependencies such as xarray and pandas have done so.
Remove get_nid and get_nid_codes functions since NID now has a
ArcGISRESTFul service.

New Features

Add a new class called NID for accessing the recently released National Inventory of Dams web service. This service is based on ArcGIS's RESTful service. So now the user just need to instantiate the class like so NID() and with three methods of AGRBase class, the user can retrieve the data. These methods are: bygeom, byids, and bysql. Moreover, it has an attrs property that includes descriptions of the database fields with their units.
Refactor NWIS.get_info to be more generic by accepting any valid
queries that are documented at USGS Site Web Service.
Allow for passing a list of queries to NWIS.get_info and use
async_retriever that significantly improves the network response time.
Add two new flags to interactive_map for limiting the stations to
those with daily values (dv=True) and/or instantaneous values (iv=True). This function now includes a link to stations webpage on USGS website.

Use persistent caching for all send/receive requests that can significantly improve the network response time.
Explicitly include all the hard dependencies in setup.cfg.
Refactor interactive_map and NWIS.get_info to make them more efficient and reduce their code complexity.
