Unfenced Cattle
Cattle destroy banks and overhanging vegetation. Woody vegetation
hanging over the streams provides predation protection, macroinvertibarate
food, and shade. |

Cattle Stream Ford
Destroys redds and habitat as they cross streams leaving tokens
in the trail. |

Bank Destruction
Along unfenced streams from livestock. Siltation results
in covering the egg masses and makes gravel substrates untenable.

Flooded Fields
Cross- field flow picks up fertilizer, pesticides, and animal wastes.
From this field excess water flows into the streams - solar heated
and polluted. This can be prevented to a great extent by not
allowing the flood irrigation water to quite reach the stream edges
of the fields. |

Flood Irrigation Runoff
Hot nutrient-rich water is carried directly into the streams

These photographs were all taken in early April 2007.
