Get external flow data not from USGS for NPS calculations

Usage

util_nps_getextflow(pth, loc, yrrng = c(2021, 2023))

Arguments

pth: Path to the external Excel file
loc: Location of the external flow data. Options are 'LMANATEE', 'TBYPASS', or '02301500'.
yrrng: Numeric vector of length 2 indicating the year range to filter the data. Default is c(2021, 2023).

Value

A data frame of flow data for the location in loc

Details

This function retrieves and formats external flow data that cannot be obtained from the USGS API. The three required locations are Lake Manatee, Tampa Bypass Canal (s160), and the Alafia River Bell Shoals Bell Shoals.

External data can be obtained as follows:

LMANATEE: Lake Manatee flow for the Manatee River dam, from Manatee County Utilities, input flow is cfs (Manatee County contact is Amanda ShawverKarnitz, amanda.shawverkarnitz@mymanatee.org).
TBYPASS: Tampa Bypass Canal flow from Tampa Bay Water. Input flow is MGD and is converted to cfs (Tampa Bay Water contact is Cathleen Jonas, cjonas@tampabaywater.org).
02301500: Alafia River Bell Shoals flow data from SWFWMD WMIS Pumpage Reports for Permit 11794 or optionally from Tampa Bay Water reported withdrawals for Site 4626 (Cathleen Jonas, cjonas@tampabaywater.org). Input flow from latter is daily average converted to cfs.

System files are included in the package which can be updated annually.

Examples

# lake manatee
pth <- system.file('extdata/nps_extflow_lakemanatee.xlsx', package = 'tbeploads')
extflo <- util_nps_getextflow(pth, loc = "LMANATEE")

# tampa bypass
pth <- system.file('extdata/nps_extflow_tampabypass.xlsx', package = 'tbeploads')
extflo <- util_nps_getextflow(pth, loc = "TBYPASS")

# bell shoals
pth <- system.file('extdata/nps_extflow_bellshoals.xls', package = 'tbeploads')
extflo <- util_nps_getextflow(pth, loc = "02301500")
