| Data Used to Assess Water Quality: | Lahontan RWQCB staff and USBLM staff evaluated conditions at Hot Springs Canyon Creek in May 2007.
Compliance with the objectives was assessed through stream bank and riparian surveys, field inspection, and review of the U.S. Bureau of Land Management grazing program and grazing intensity. According to USBLM staff, grazing management practices were updated and implemented beginning in 1993. These practices and decreasing numbers of livestock have resulted in improvements to the watershed over a 20 year period. The 2007 inspection did not show significant bank trampling or current impacts on vegetation. Areas with stream incision may be due to natural conditions (highly erodible volcanic soils) and/or to past grazing practices. There is heavy vegetative cover currently present along the stream channel and banks in the incised areas. The USBLM's 2000 Rangeland Health Assessment for this watershed concluded that "there are no significant environmental impacts from current use and the allotments meet Rangeland Health Standards." The assessment also concluded tht livestock use in the Hot Springs Canyon allotment is generally highly dispersed iwth light use, and that riparian vegetation in the immediate vicinity of the geothermal springs istypically at or near 100 percent.

| Water Quality Objective/Criterion: | The applicable water quality objectives are:
(1) Sediment- The suspended sediment load and suspended sediment discharge rate of surface waters shall not be altered in such a manner as to cause nuisance or adversely affect the water for beneficial uses. (2) Settleable materials- Waters shall not contain susbstances in concentrations that result in deposition of material that cause nuisance or that adversely affects the water for beneficial uses. |

| Spatial Representation: | Lahontan RWQCB staff conducted a visual assessment of approximately 1 mile of the creek. The USBLM assessed the entire 2.9 mile stream segment.t |
| Temporal Representation: | Initial listing was based on USBLM surveys conducted in 1988. The USBLM conducted a rangeland health assessment in June 2000. A visual assessment of the creek was conducted by RWQCB and :USBLM staff in May 2007. |
| Environmental Conditions: | Hot Springs Canyon Creek is an intermittent stream that flows from the Bodie Hills to Bridgeport Valley in Mono County. The stream was listed in 1988 based on stream and riparian zone surveys at one station, not on quantitative sediment data. |
| QAPP Information: | Quality Assurance information is described in the USBLM Bishop Resource Management Plan (RMP) and the Central California Standards for Rangeland Health and Guidelines for Livestock Grazing Management. |
