i couldn't find the raw data on that website, although this report has a good summary
http://www.hilobaywatershed.org/research...202009.pdf
see table 3 on page 62/135. the important column is the sum of rainfall over the previous 5 days. none of those values were ever zero, which indicates no rainfall in the previous 5 days. when the rainfall over the previous 5 days was at a minimum, the flow rate was very low, up to 100 times less (compare base 4 to storm 4).
i haven't looked at the recent rainfall data at hilo airport, which is what the document references, but up in mtn view, it has not rained for going on a week, so in relation to the data in the table, we are at a minimum.
just because no one on punaweb has not contradicted it, does not mean it didn't happen. a very small percentage of the population visits this site, and the majority of the users are relatively new here, versus longtime residents who have seen that river for decades and decades.
i'm not convinced that the river being dry is not normal. to make assumptions about what is normal, one must be familiar with not only the last 5 years, but also the last 50 years, and even better, the last 500 years.
it is difficult to compare hawaii to california, they are different in so many ways, especially the ways the volcanoes are formed. it's comparing apples to oranges.
