dc.description.abstract | Six wetland areas were constructed in the fluctuation zone of Black Butte Reservoir near Orland, CA, in November of 1991. The wetlands were to function as wildlife habitat and sediment traps. The wetlands ranged in size from less than 1 acre to approximately 3 acres for a total area of about 8 acres. The wetlands were constructed using simple low-cost techniques at an estimated cost of $40,000 for materials and labor. Careful selection of sites aided in controlling construction costs. After construction, the wetland water levels and sediment accumulation were monitored. During the first 2 years of monitoring, the wetlands were inundated for much of the time, much longer than under normal conditions. During the last year of monitoring, the wetlands were inundated for a much shorter period, closer to normal conditions. Sediment accretion in all the wetlands was high, ranging form 5.6 to 89.2 m.m/year (2.0 to 42.5 kg/m²). Sediment accretion varied between wetlands, years, and measurement techniques. Sediment accretion in the wetlands also varied with elevation, with higher sediment accretion occurring at sites with lower elevations. | en_US |
