acewater provides an interface to the real-time water monitoring data provided by the Water Management Section of the Seattle District Corps of Engineers, which covers most of Washington, Northern Idaho, and Northwestern Montana. The main function, get_water_conditions returns a tidy data frame (a tibble).

Installation

You can install acewater from github with:

# install.packages("devtools")
devtools::install_github("briandconnelly/acewater")

Example

Get the current conditions at the Grand Coulee Dam (GCL), part of the Eastern Washington Rivers (EWA) project:

library(acewater)

(gcl <- get_water_conditions(station = "GCL", project = "EWA"))
#> # A tibble: 42 x 6
#>          Time Project Station Depth     Measure   Value
#>        <dttm>  <fctr>  <fctr> <dbl>      <fctr>   <dbl>
#>  1 2017-06-03     EWA     GCL    NA ElevForebay 1263.29
#>  2 2017-06-04     EWA     GCL    NA ElevForebay 1265.77
#>  3 2017-06-05     EWA     GCL    NA ElevForebay 1267.69
#>  4 2017-06-06     EWA     GCL    NA ElevForebay 1269.61
#>  5 2017-06-07     EWA     GCL    NA ElevForebay 1271.45
#>  6 2017-06-08     EWA     GCL    NA ElevForebay 1272.87
#>  7 2017-06-09     EWA     GCL    NA ElevForebay 1274.10
#>  8 2017-06-10     EWA     GCL    NA ElevForebay 1275.37
#>  9 2017-06-11     EWA     GCL    NA ElevForebay 1276.71
#> 10 2017-06-12     EWA     GCL    NA ElevForebay 1277.87
#> # ... with 32 more rows

We can easily plot the water conditions for a given station (if ggplot2 is installed).

library(ggplot2)

autoplot(gcl)

Get the most recent conditions at the Fremont Bridge (station FBLW) in the Lake Washington Ship Canal (project LKW):

Here, we see that this station monitors different properties:

(fblw <- get_water_conditions(station = "FBLW", project = "LKW"))
#> # A tibble: 156 x 6
#>                   Time Project Station Depth  Measure Value

Get Conditions from Multiple Stations

We can use purrr to combine data from multiple stations into a tidy data frame. Here, we'll get data from a few stations along the Lake Washington Ship Canal.

(lkw <- purrr::map_df(c("UBLW", "FBLW", "LLLW"), get_water_conditions, project = "LKW"))
#> # A tibble: 520 x 6
#>                   Time Project Station Depth  Measure Value
#>                 <dttm>  <fctr>   <chr> <dbl>   <fctr> <dbl>
#>  1 2017-06-15 12:00:00     LKW    UBLW     8 Salinity  0.03
#>  2 2017-06-15 13:00:00     LKW    UBLW     8 Salinity  0.03
#>  3 2017-06-15 14:00:00     LKW    UBLW     8 Salinity  0.03
#>  4 2017-06-15 15:00:00     LKW    UBLW     8 Salinity  0.03
#>  5 2017-06-15 16:00:00     LKW    UBLW     8 Salinity  0.03
#>  6 2017-06-15 17:00:00     LKW    UBLW     8 Salinity  0.03
#>  7 2017-06-15 18:00:00     LKW    UBLW     8 Salinity  0.03
#>  8 2017-06-15 19:00:00     LKW    UBLW     8 Salinity  0.03
#>  9 2017-06-15 20:00:00     LKW    UBLW     8 Salinity  0.03
#> 10 2017-06-15 21:00:00     LKW    UBLW     8 Salinity  0.03
#> # ... with 510 more rows
