| Abstract: |
The hydrogeochemistry of nine streams in the Caribou-Poker Creeks Research Watershed (CPCRW) during the summers of 2002 – 2006. In summer 2005, Boston Creek, which is located ca. 20 km east of the CPCRW was sampled. The Boston Creek watershed was extensively burned during the Boundary Fire of 2004. Samples were analyzed for Ca, Mg, Na, K, NH4+, Si, Cl, NO3, SO4, DOC, TDN, DIC, SUVA, pH and conductivity.

Boston Creek -- Stream water sampling location.
C1 -- The C1 basin is the western-most headwater tributary of Caribou Creek.
C2 -- The tributary basins of Caribou Creek are all arbitrarily designated with a
"C". The C2 basin is the sub-basin with the least amount of permafrost of the CPCRW sub-basins. As such, it has been often been studied intensively in conjunction with C3, the sub-basin with the greatest amount of permafrost. The basin trends to the south, with well-drained slopes and permafrost-underlain treeless muskeg in valley bottom. Although an extensive fire history has not been done, there was probably a stand-replacing fire early in this century (ca. 1925), with some large white spruce stands that survived from the earlier vegetation.
C3 -- The tributary basins of Caribou Creek are all arbitrarily designated with a
"C". The C3 basin is the sub-basin with the most permafrost of the CPCRW sub-basins. As such, it has been often been studied intensively in conjunction with C2, the sub-basin with the least amount of permafrost. The basin trends to the northeast, with black spruce/feather moss slopes and permafrost-underlain treeless muskeg in valley bottom.
C4 stream -- The tributary basins of Caribou Creek are all arbitrarily designated with a "C". The C4 basin is the largest of the Caribou Creek tributaries, and enters Caribou Creek about 400 m above its confluence with Poker Creek. The flume in C4 is about 1 km upstream from the confluence of Little Poker Creek and Caribou Creek. There is an intermittent tributary called Dry Gulch that drains the Caribou Peak area, and which has a small Parshall flume on it.
The basin has a tributary known as Dry Gulch that drains the Caribou Peak area, and is intermittent in its lower reaches but may be permanent on the steeper upstream slopes.
More information can be found at CPCRW Real Time Meteorological Stations at the Water and Environmental Research Center
CB -- This site is on the Caribou Creek main stem above the confluence with C3, so it is the combination of the C1 and C2 basins. This is an interesting site: it has the only well developed canopy of riparian trees in CPCRW, and it is always the first to thaw in the spring and the last to freeze in the fall.
CJ -- The CJ site is in Caribou Creek immediately above (about 30 m) the confluence of Caribou and Poker Creeks. There is a pressure transducer measuring stream stage and a thermistor string measuring water temperatures at depths of 0, 10, 20, and 50 cm in the streambed sediments.
P6 -- Basin in Caribou-Poker Creeks Research Watershed
PC --
PJ -- This site encompasses the Poker Creek basin above the confluence with Caribou Creek. There is a pressure transducer measuring stream stage, and a string of thermistors measuring water temperature at 0, 10, 20, and 50 cm deep in the stream sediments.
