- Description:
- Suspended sediment was investigated above and below beaver ponds in the Beaver Creek drainage in the south central mountains of Idaho near Idaho City from March 1979 through September 1979. The study was to identify the potential for beaver ponds as settling basins for suspended sediment in wildland watersheds. Two sampling stations were established above and below a beaver colony. The parameters measured included suspended sediment, stream discharge, and water temperature. Also, the beaver pond volumes and surface areas and beaver dam lengths and heights were measured. The data were collected weekly from March through September, except during May and June when sampling was more frequent to bracket the peak flow period. The data demonstrated that suspended sediment was deposited in the beaver ponds. The proportion of suspended sediment deposited in the beaver ponds averaged about 38 percent on the rising limb, 10 percent during the peak flow period, and 65 percent on the falling limb. The suspended sediment ratio was negatively correlated with stream discharge and positively correlated with water temperature. The relationship between the suspended sediment ratio and the stream discharge and water temperature was significant at the 0.05 level. The quantity of suspended sediment deposited in the beaver ponds during the study period was 78.2 tons, which was approximately 25 percent of the suspended sediment load transported through the above sampling station.

- Description:
- The abundance, seasonal distribution, holding habitat and behavior of adult summer steelhead were studied during the summers of 1979-1981 in the Trinity River system, California. The North Fork Trinity River and New River were the only streams in the drainage harboring significant numbers of steelhead during the summer months. Estimated combined run size for both streams ranged from a maximum of 776 fish in 1980 to a minimum of 455 fish in 1981.
Summer steelhead began entering the tributaries in early June; entry peaked during mid-July. Steelhead numbers and distribution had substantially stabilized by early August. Summer steelhead were tagged in a single holding pool in the North Fork Trinity River during September 1981. Subsequent surveys revealed that they remained in that pool until the first storm fronts had passed through the area in early October, at which time small groups of fish rapidly migrated upstream. However, some tagged fish were still present at the tagging site in early November. High stream discharge precluded further survey work after that time.
Holding pools do not appear to be a limiting factor for adult summer steelhead in either tributary. During the study period, the percentage of pools harboring one or more adult summer steelhead ranged from a minimum of 14 percent to a maximum of 36 percent in the North Fork; corresponding values for the New River were 27 percent and 31 percent.
Twenty-seven pools in the New River were surveyed periodically during the summer of 1980. Factor analysis suggested a relationship between steelhead numbers in pools and available cover and shade, but failed to show a relationship between steelhead numbers, pool dimensions, upstream gradient, downstream gradient or distance to first downstream pool. Although no statistical analysis of steelhead numbers and other pool variables was performed for the North Fork Trinity River, observations indicate a high correlation between steelhead numbers and pool dimensions in that stream. Gold-dredging activity was heavy in the New River watershed, and appeared to have had an effect upon steelhead distribution among holding pools in that stream. Heavy poaching activity is a significant threat to the continued survival of the summer steelhead run in the New River drainage.
U.S. Forest Service barrier modification efforts in the North Fork Trinity River appeared to have had an effect upon summer steelhead distribution. Steelhead were observed in greater numbers in upstream areas, and were concentrated in a fewer numbers of pools, after barriers were modified.
Analysis of scales taken from North Fork Trinity River summer steelhead revealed that 95 percent of returnees smolted at age 2, 44 percent of returnees made their initial upstream migration as "halfpounders", and 42 percent of returnees were repeat spawners.

- Description:
- Lecture delivered via webinar on November 12, 2020. Leena Dallasheh is an associate professor of history at Humboldt State University. She received her PhD in the joint History and Middle Eastern and Islamic Studies program at NYU. Her areas of specialization are the social and political history of the modern Middle East and modern Palestinian and Israeli history. Her research focuses on the social and political history of Nazareth from 1940 to 1966, tracing how Palestinians who remained in Israel in 1948 negotiated their incorporation in the state, affirming their rights as citizens and their identity as Palestinian. This lecture is part of Humboldt State University's Sustainable Futures Speaker Series, which is sponsored by the Schatz Energy Research Center, the Environment & Community graduate program, and the College of Arts, Humanities & Social Sciences.
