As water is becoming less available during summer seasons, water managers are putting more emphasis on water storage and allocation during "high water season." While there are established methods and some consensus on how to determine direct fish habitat flows there is less consensus and information on how to set aside elevated flows for channel habitat maintenance and other ecological flow needs. This paper discusses a method which allows for the conditioning of instream water rights based on known processes including channel maintenance flows and ecological trigger flows. In other words, this document provides guidance in allocating peak flows.
