* Miscellaneous Flow includes fish ladders, PH1 sluiceway, navigation lock,
PH2 DSM, UMT, and PH2 corner collector (B2CC). When all routes are in
operation (March-August), total Misc Flow will be ~12.4 kcfs. Flow through
the B2CC is ~5 kcfs, so fluctuations of +/-5 kcfs at any time of year
indicate the B2CC is open/closed.
