“…Ephemevella and most of the species of Hydropsychidae had previously emerged during the spring and were unavailable as a food item during the summer. Newell (1976) reported that the mayflies Rhithvogena and Tvavevella are insects which inhabit swift current areas.…”

“…However, this insect is not considered to be an important food item in the diet of shovelnose sturgeon in the study area. Newell (1976) reported that the velocity requirement for Heptagenia is substantially less than that of Rhithvogenia and Tvavevella. This observation provides further evidence to support the idea that shovelnose sturgeon feed nonselectively in swift current areas in the middle Missouri River.…”

“…Two mayflies, Rhithrogena and Traverella, comprised 58 percent of the food volume in the summer diet of shovelnose sturgeon in the middle Missouri River (Gardner and Berg 1981). Traverella are also abundant in the lower Yellowstone River (Newell 1976). They accounted for 46 percent of the food volume in the diet of shovelnose sturgeon in the lower Yellowstone from July to September (Elser et al 1977).…”

Before the Montana Board of Natural Resources and Conservation in the matter of water reservation application nos. 69903-410 ... in the Upper Missouri River Basin : Department of Fish, Wildlife and Parks' objector testimony

ISSl and Conservation in the natter of water reservation application nos. 'V. Percentile Flows (cfs) 90th 80th 50th 20th August 602 724 1,227 1,647 To satisfy MDFWP's August instream flow right of 1,300 cfs and, at the same time, supply 118 cfs for the project, a minimum of 1,418 cfs must flow above the proposed diversion site. This 1,418 cfs falls between the 50th and 20th percentile flows. By interpolation, 1,418 cfs equals about the 40th percentile flow, meaning that in about 4 years-outof-10, flows will exceed about 1,418 cfs. Thus, in only about 4 years-out-of-10 will sufficient flow be available to fully satisfy the project's water demand. How does this level of water availability affect project feasibility? GA-201 is a potential seed potato project. The project application selected a rotation pattern of one year small grain, one year potatoes, one year small grain, and three Nelson Objector's-7 Boulder River Q. Which reservation application does this objection testimony pertain to? A. This objection testimony pertains to JV-17, JV-18, JV-63, JV-80, and JV-81. The source of supply are wells adjacent to the Boulder River. According to the draft EA for the reservation application of the Jefferson Valley Conservation District, pumping from these wells will reduce flows in the Boulder River. Q. Why is the MDFWP objecting to these projects? A. The mid-segment of the Boulder River where these proposed Nelson Objector's-8 projects are located is already characterized by severely reduced summer flows, a consequence of existing irrigation depletions. Granting these reservation requests would aggravate an already intolerable situation, further reducing the river's depressed trout populations. Describe the trout populations in the mid-segment of the Boulder River between the town of Boulder and the Cold Springs where the above projects are located. Within this stretch, MDFWP, in 1974, obtained population estimates for three sections, ranging from 3,200 to 12,200 ft., using electrofishing techniques. The three study sections supported an estimated 15.2, 15.4, and 26.6 pounds of trout per 1,000 ft. of river. Numbers of trout ranged from 39 to 52 per 1,000 ft. These severely depressed trout populations reflect a number of environmental problems, stream dewatering being one of the more notable. Below the Cold Springs, the trout population recovers to a respectable 242 fish, weighing 70.2 pounds, per 1,000 ft. The outflow of the Cold Springs (about 30 cfs) contributes to this recovery. The five projects, however, are all located upstream from the Cold Springs along a stream segment that is already plagued by summer dewatering. How severe is summer dewatering in this mid-river segment? The only USGS gauge site in the mid-segment of the Boulder River is located near the town of Boulder at about the upstream boundary of this mid-segment. This gauge site does not reflect the flows that presently occur below the proposed projects, upstream from the outflow of the Cold Springs. Historic flows at the near Boulder gauge are summar...
