# Definitions:
#     reservoir_storage = actual storage at measured lake elevation
#     dead_pool_capacity = storage at dead pool elevation
#     conservation_capacity = storage at conservation pool elevation - dead pool capacity
#     conservation_storage = reservoir storage - dead pool capacity (note: conservation storage is capped at conservation capacity)
#     percent_full = 100 * conservation storage/conservation capacity

# Footnote:
#     The elevation-storage rating curve used to produce the storage
#     hydrograph is made of two segments: (1) the segment up to the
#     conservation pool top (below the red line) is based on measured data,
#     and (2) the segment in the flood pool (above the red line) is an
#     extrapolation from the first segment and shouldn't be relied upon for
#     flood storage information.
# 
# Data from 2025-05-02 00:00:00 to 2025-06-01 08:30:00 is marked as provisional by the USGS.
