Waimanalo Adventures

 

Ed Gilman & I entered Bear Claw vicinity today,  to survey the only remaining part of the Maunawili Ditch that we had not yet seen. (Unlike Kailua Ditch, most of what is visible from Waikupunaha,  Maunawili Ditch must be searched out).
 
Entered Ditch right above Bear Claw Water-tank.  Surprisingly, full concrete walls and floor.  (Originally,  the Waimanalo Irrigation system was mostly dirt floor and walls,  with wooden flumes used for crossing gulches.)  There were much concrete improvements as we followed the ditch in the Kailua direction.  Eventually we were beyond these improvements.  It seems that at one time,  money was allocated for improving the Ditch starting at Bear Claw and working backwards ("they" must have intended to reopen water use for the Ditch).  Money apparently ran out, and this portion of the Ditch was never used again anyway.  Most of  the many miles of Maunawili Ditch (in Waimanalo) is dry,  the water having entered a pipe soon after going thru Anianinui Tunnel. 
 
Somewhere in the vicinity of Bear Claw Right & Power-line,  a gamecock farmer has encroached on the ditch and (a significantly large area) mauka of the ditch.  Not wanting to intrude on anyones' farm,  legal or otherwise,  we backtracked, and did a major mauka bypass.  After that, back to the ditch; continued on until properties are close to Ditch on both sides. 
 
Made another mauka bypass.  Came across significant  Hawaiian Rock Mounds.  Three or four total.   Excellent condition.  Have never heard or read about these.  Appear to be some type of "alters".  May have been for sacrifice.   Human sacrifice?  
 
Hiked thru the forest (tall trees of long ago re-forestation),  on another ditch(!) about 100 feet higher in elevation than main Ditch.  Where would this Ditch ( not seen on any maps that I have reviewed),  lead?
 
Gets to  a major Board of Water Supply facility.  Ditch blocked by concrete.   Must have been that  this Mauka Ditch was feed by a tunnel or spring which is now used by Board of Water.  (Located mauka of Kaulakanu).
 
We wanted to get to the Ditch Tunnels near Mahailua,  but not via the portion of the Ditch that now has properties close on both sides.  We would stay at the higher elevation and make our way over.   Ended up coming across old graded contour road.  Some portions still used occasionally by HECO.   Roads  must have been cut by Plantation long time ago.
 
Got to the point were one map shows Pohakunui Heiau being makai of Ditch.  Does anyone know where Pohakunui actually is?   I think it may exist mauka of Ditch and road.  
 
Anyway,  descended target gulch, and found Ditch.   We proceeded to walk/crawl thru the two tunnels (only shown as one tunnel on map),  in the former flow direction.  Then headed back thru the two tunnels again.  These are low tunnels, not very easy to go thru.  Amazing,  no concrete re-enforcement,  just dug out with dirt walls and ceiling,  and these tunnels still exist!
 
Back at the target gulch, followed the Ditch short way (other direction) until tunnel that goes under Mahailua.  Unfortunately,  Tunnel entrance there is totally blocked by debris,  rubbish, slide, etc.
 
The whole Ditch System was amazing.  Tremendous labor went into the construction.  Many tunnels and springs were used.   In the Maunawili Side  the formerly beautiful wooden flumes have been replaced with siphons, in there areas where the Ditch is still used.  Of that,  most water leaks out before reaching Anianinui Tunnel.  The dam intakes still exist.
 
The Maunawili Ditch System is "Qualified for National Historic Status".  But the powers that be never took the next step,  so in reality,  almost no one sees any of it,  and the elements are slowing disintegrating the system...
 
Anyway,  it was good fun exploring these areas, that virtually no one today sees.  But 100 years ago many Plantation workers toiled there.  And for 1000+ years before that,  these areas were  inhabited and important to the Kanaka Maoli.    Truth is, the Ditch would make an excellent hiking trail for Na Ala Hele...
 
Aloha,
