Samidare ni numa no iwagaki mizu koete makomo karubeki kata mo shirarezu - Kinyo Wakashu(English Translation & Meaning)

五月雨に沼の石垣水越えて
真菰刈るべき方も知られず

Roma-ji: Samidare ni numa no iwagaki mizu koete makomo karubeki kata mo shirarezu
English Translation: In the early summer rain
over the marsh's stone wall
the water has spilled,
and where the wild rice is reaped
none can tell any longer
Meaning: In the early summer rains the water has spilled over the stone wall of the marsh, and one can no longer tell where the wild rice should be cut.
Commentary: Book Two Summer Poems 135

The incessant early summer rain has made the water overflow the marsh's stone wall, so that one can no longer even tell where the wild rice is to be cut. The rising waters of the summer rain are depicted through a concrete scene beside the marsh.
From poem 135 through poem 140 in this book come poems on the early summer rains, depicting how the long, unceasing rain swells the waters and sinks the landscape beneath them.
The author, Morayori, is Minamoto no Morayori. A son of the Minister of the Left Minamoto no Toshifusa, he rose to Senior Second Rank and Major Counselor and was known as the Ononomiya Counselor. A story survives of how swiftly he could compose a hundred-poem sequence.

First line, 'samidare ni', means because of the summer rains, giving the cause.
Second line, 'numa no iwagaki', is the stone wall built along the marsh.
Third line, 'mizu koete', shows the water overflowing the wall, the level having risen.
Fourth line, 'makomo karubeki', means where the wild rice should be cut.
Final line, 'kata mo shirarezu', uses re, the potential auxiliary ru: one cannot even tell the place.
