Enable mapping of real-time streamflow with historic percentiles
User story: As a water resources manager, I want to have quick access to maps showing the status of water availability in my state compared to previous years.
This feature will enable downstream users to create national-scale maps.
- Pull NWIS data of current streamflow
- Calculate historical percentile values for all sites with current conditions for the day of the year on daily, 7-day, 14-day, 28-day average timescales
- Create a standardized data output to enable downstream mapping of data and percentile values at the site, state and HUC2 scales
Calculations:
- Average streamflow on daily, 7-day, 14-day, 28-day timescales
- Percentile classes and ranking
Considerations:
- need to handle negative flows
Nice to have:
- filtering dataset to the HCDN network, as per Xiaodong Jian recommendation
