Not really sure what the maximum recommended flow might be in here. Getting the minimum is hard enough. You will have some additional water from Chilkoot creek in this lower section. Boatable flows tend to be in April and May but can occur in other months as well. See this table of Monthly mean flows; 1997-2006.
Historical data and other information can be found at USGS NF Willow gage #11242400. Madera Irrigation District maintains this flow gauge. MID diverts some water from NF Willow upstream near Soquel Meadow over to California Creek which drains eventually into the Fresno River for use by valley agriculture.
Since October of 2009, the CDEC has hosted the gauge data, so newer flow data is at CDEC-NFW.
