<br />FIGUE.E 3.-Location of flood-determination points, floods of January and Feb-
<br />. ruary in Maui, Hawaii.
<br />
<br />Runoff from the storm of January 23 was intense in a small area.
<br />The peak discharge in Palikea Stream near Kipahulu (sto. 2) was the
<br />maximum discharge in 38 years of record (tahle 2). A highway bridge
<br />over Lelekea Stream between Kaupa and Kipahulu was washed out.
<br />Runoff from fields crossed a highway at Hana and caused slight
<br />damage by flooding the lobhy and some rooms of the Hana Hotel.
<br />Torrential rains of 10 or more inches fell in about 8 hours on Feb-
<br />ruary 3-4 along the windward coast and slopes in eastern Maui and
<br />in the mountains of western Maui (fig. 3), Total rainfall exceeded pre-
<br />vious 24-hour maximums at several rain gages; a total of more than
<br />12 inches fell at Hana Airport. The greatest recorded total for the
<br />storm was 16.94 inches at Paakea. More than 20 inches may have fallen
<br />near Honomanu and at other places at altitudes of 1,500-2,000 feet,
<br />Rainfall totals exceeded 12 inches in the mountains in western Maui.
<br />On the leeward side at La:haina, 0.81 inch of rain fell.
<br />Peak discharges (table 3) in Kawaipapa (sta. 6) and Moomoonui
<br />(sta. 5) Gulches were slightly higher than they had been on Jan-
<br />uary 23, and runoff in the Kipahulu area was very low. Damage in the
<br />Hana area was limited to eroded pastureland, damaged fences, and
<br />washed-out roads. Numerous landslides occurred between Hana and
<br />
<br />~.
