With too many demands placed on too little water, the Klamath Basin and itsresidents - human and otherwise - are in dire need. There exists a significant opportunityfor mitigation in the purposeful conversion of seasonal wetlands to permanent wetlandsmanaged to increase baseline water storage levels in the Upper Basin. A...
Larval transport and retention of two endangered suckers were studied in a highly
altered lacustrine/riverine complex. The endangered populations of Lost River sucker,
Deltistes luxatus, and shortnose sucker, Chasmistes brevirostris, in Upper Klamath Lake
(UKL), Oregon are the largest remnant populations of these suckers. Downstream of
UKL, the Keno Impoundment...
The fishes of Upper Klamath Lake appeared to distribute
themselves in three general groups during the summers of 1964
and 1965: (1) the chubs--unrestricted as to distribution with slight
seasonal variations; (2) rainbow trout and yellow perch -- restricted
to certain water conditions that exist only along the northern marsh...
The purpose of this thesis is to examine the problem of the
increasing competition between recreation and irrigation at Wallowa
Lake. Originally Wallowa Lake was an abundant source of fish for
the Indians but the advent of irrigation in the area by the early settlers eliminated the blueback salmon (oncorhynchus...
Upper Klamath Lake in southern Oregon has two species of lacustrine suckers,
Lost River sucker Deltistes luxatus and shortnose sucker Chasmistes brevirostris that
were historically abundant. Results of surveys performed in the mid-1980's indicated that populations of both species were declining and ageing with apparent recruitment failure in most years...
Upper Klamath Lake in south central Oregon annually experiences intense
blooms of cyanobacteria, primarily Aphanizomenon flos-aquae. Domination of the
lake phytoplankton community by this single species regularly results in drastic
changes to water quality. Photosynthetic activity of such extensive populations can
result in pH over 10. Blooms typically expire in...
