In the early summer of 1926 I spent nearly two months in the vicinity of Lillooet, B. C., a typical “dry-belt” locality, studying the insect fauna of this region. My headquarters were at Craig Lodge, at the east end of Seton Lake, a large body of water about three miles west of Lillooet draining into the Fraser River through Seton Lake Creek, which is joined about a mile to the east by the larger Cayoosh Creek, entering from the south through the deep and precipitous Cayoosh Canyon. The general nature of the country has already been ably indicated by Mr. R. Glendenning in a paper on the Fauna and Flora of Mt. McLean which appeared in the Proceedings of the British Columbia Entomological Society for 1921.

Bed Material

The lower main channel of the Fraser River, British Columbia, is a sand-bed, salt-wedge estuary in which variations in velocity, discharge, and bedform characteristics are contolled by river discharge and the tides. Bed-material composition remains consistent over the discharge season and in the long term. Changes in bedform height and length follow but lag behind seasonal fluctuations in river discharge. Migration rates of bedforms respond more directly to river discharge and tidal fall than do height and length. Bedform characteristics were utilized to estimate bedload transport in the estuary, and a strong, direct, but very sensitive relationship was found between bed load and river discharge. Annual bedload transport in the estuary is estimated to be of the order of 0.35 Mt in 1986. Bedload transport in the estuary appears to be higher than in reaches upstream, possibly because of an increase in sediment movement along the bed to compensate for a reduction in suspended bed-material load produced by tidal slack water and the salt wedge.

Microtus Townsendii

A 2-year livetrapping study on Townsend's vole (Microtus townsendii) on Reifel Island in the Fraser River delta in British Columbia, Canada, showed that there was an early stop to summer breeding in the peak phase summer compared with the increasing phase summer. Selective dispersal and death of early-maturing voles may account for this result. A delay occurred in the onset of breeding in the decline phase. Voles in peak density populations had the highest median weights at sexual maturity, and males matured at heavier weights than did females.
