This report presents the results of an overview hydrologic assessment of the Tyner Creek sub-basin, located north-west of Merritt. Aspen Planers Ltd. (Merritt Division) initiated the study, partly in response to results of the Merritt Forest District IWAP completed in 1997, and partly to address concerns from the Ministry of Forests. Concerns included: peak flows, surface erosion, and stream temperature. Fieldwork was carried out in September 1998. Tyner Creek sub-basin, with an area of 208 ha, drains east into Guichan Creek, which is part of the Nicola River watershed. The sub-basin's point of interest is Tyner Creek at its confluence with Guichon Creek. Mining, forest harvesting, grazing, and recreational uses are all identified activities in this sub-basin. Forest harvesting dates back to the late 1980's. Active mining claims can be found all along Tyner Creek except at the mouth. No water licenses are associated with Tyner Creek and one BCFS recreation site is located within the sub-basin boundary. The Merritt District IWAP delineates the main stem of Tyner Creek as fish bearing up to Tyner Lake. Tyner Lake is also reported to be fish bearing. The Tyner sub-basin occupies a moderately steep sided valley with a flat upper plateau. There are small marshes dispersed in the upper sections of the channel network. Surficial materials are sands with varying amounts of coarse material. Surficial geology consists of undifferentiated morainal deposits with scattered rock outcropping in the upper sub-basin and hummocky gravels and stream terraces near the mouth. Rock outcrops consists if very friable and coarse granitic rocks. At one creek section (1220 m el.) bluffs made of these rocks were eroding very course sand into the creek. |
