| Topic | Temperature: Min, Max, Ave Hayfork (NRCS Site 01) @ Nine Mile Br.1997 |
| Caption: The minimum, maximum and average water temperature at Nine Mile Bridge on Hayfork Creek, below Hayfork Valley, in 1997 was very similar to 1996 (se previous Topic) except that elevated temperatures started earlier in the season. By mid-June, conditions were acutely stressful with even the minimum water temperature above stressful. High water temperatures at Nine Mile Bridge may be in part exacerbated by water withdrawals and riparian conditions related to agricultural activities in Hayfork Valley upstream. Data collected by the Trinity County RCD and Weaverville office of the USDA Natural Resources Conservation Service. See Picture for a map view of gauge location. | |
