  	Citation × Citation Citation Abstract Copy Title: Distribution and biology of suckers in Lower Klamath reservoirs : 1999 final report Author: Desjardins, Marc; Markle, Douglas F. Year: 2000, 2005 Abstract The objectives of this two-year study (1998-1999) were to document distribution, abundance, age class structure, recruitment success, and habitat use by all life history stages of shortnose and Lost River suckers in three lower Klamath River hydroelectric reservoirs (J. C. Boyle, Copco, and Iron Gate). Lost River sucker catches were sporadic (only 3 adult individuals total) and the focus of our analyses, therefore, shifted to shortnose suckers. Adult and larval suckers were found in all reservoirs both years. All life history stages (larvae, juveniles and adults) were found in J. C. Boyle during both years and in Copco in 1999. Juvenile suckers were not found in Copco in 1998. The number of adult shortnose suckers was highest in Copco reservoir (n=165), followed by J.C. Boyle (n=50) and Iron Gate (n=22). Larger and older individuals dominated Copco and Iron Gate reservoirs and little size structure was detected. J. C. Boyle tended to have smaller adult shortnose suckers and many size classes were present. Unidentifiable larval suckers were most abundant in Copco reservoir where historic spawning of shortnose suckers has been documented. Larval suckers in Copco and Iron Gate reservoirs were most abundant in mid to late June before quickly disappearing from catches. J. C. Boyle larval suckers peaked in mid July, attained larger sizes, and were caught later in the season. It appeared that recruitment of young-of-the-year suckers only occurred in J. C. Boyle with downstream reservoirs recruiting older individuals, perhaps those that had earlier recruited to J. C. Boyle. Tagging studies could clarify adult recruitment dynamics and an additional study of juvenile recruitment would be needed to confirm these patterns. Predation pressure may be somewhat reduced in J. C. Boyle in comparison to the other reservoirs as its fish community was dominated by native fishes while communities in Copco and Iron Gate reservoirs were dominated by exotic predators. J. C. Boyle also possessed proportionally more littoral habitat, which suggests it may provide a more stable environment for young fishes. However, our sampling was inadequate to demonstrate such relationships due to high variance in larval and juvenile catches and potentially confounding habitat variables. One such variable was water level fluctuations, which could interact with habitat and resource availability in complex ways. For example, water level fluctuations, presumed to have a negative impact, were greatest in J. C. Boyle. Extrapolation from the literature suggests it should have had the poorest habitat for larval and juvenile suckers, but our results indicated J. C. Boyle had the most young suckers. Additional study of the relationships between water level fluctuations, habitat availability, the exotic fish community, and juvenile sucker recruitment would be needed to better understand early life history ecology of endangered lake suckers in these systems.

  	Citation × Citation Citation Abstract Copy Title: EPA 314 clean lakes program: phase I diagnostic/feasibility project: Upper Klamath Lake, Oregon Author: Klamath Consulting Service, Inc Year: 1983, 2006, 2005 SUMMARY PROBLEM DEFINITION Upper Klamath Lake, a 90,000 acre body of water located in south-central Oregon, is eutrophic and has reached a stage where summer algal and macrophyte productivity causes severe aesthetic problems and often renders the lake unusable as a recreational site. The problem is a natural one; it has not been caused by man's carelessness and cannot be turned around by regulation. Upper Klamath Lake is quite shallow, warming rapidly in the summer, and the waters carry a naturally occurring high nutrient load. Algal growth is extensive, predominently APHANEZOMENON FLOS-AQUAE, a blue-green algae prevalent in eutrophic waters. These organisms form dense mats that become very odorous as they decay. Numerous macrophytes (aquatic weeds) are indigenous to the lake, but the major problem is with P0TAM06ET0N CRISPUS, which forms long floating fonds that tangle boat motors and prevent passage. The Pelican Bay channel has an extensive growth of this weed.
