Streams/Pi’ina’au

IIFS Status: A&B to restore full flow to stream according to this report.

Other Names and Branches: Palauhulu, Kuo

Current Situation:

USGS Gage: (None)

DAR Report: (None)

IFSAR Report: https://wikiwai.org/wp-content/uploads/2024/11/PR200803-Piinaau.pdf

Lease Area: Ke’anae

Additional Information: There are two branches, but the CWRM considers this to be a single hydrological unit. The western branch is the Pi’ina’au, the eastern branch is the Palauhulu. The EMI map shows only one major branch, with different naming. The Pi’ina’au is diverted once, into the Ko’olau Ditch, but the hydrological unit has one other diversion on one of the branches.

Notes:

  • DAR = Division of Aquatic Resources. These guys assess stream biota.
  • IFSAR = Instream Flow Standard Assessment Report. This study focuses on hydrology, flow and water uses.
  • IIFS = Interim Instream Flow Standard
  • PAIFS = Petition to Amend Instream Flow Standard. You can read the PAIFS here.
  • §13-169-44 = Statutory requirement for Instream Flow. This is the fallback the CWRM uses in the absence of historical flow data. Basically it locks in whatever the situation was for the stream in 1988. You can read about it here.
