Huerfano County Stock Ponds and Livestock Tanks

Livestock water tanks are covered under the "Livestock Water Tank Act of Colorado" sections 35-49-101 to 35-49-116, C.R.S. These structures include all reservoirs built after April 17, 1941, on watercourses which the state engineer has determined to be "normally dry" and having a capacity of not more than ten acre-feet and a vertical height not exceeding fifteen feet from the bottom of the channel to the bottom of the spillway. Again, as with erosion control dams, the height is measured from the lowest point of the upstream toe to the crest of the spillway. No livestock water tanks can be used for irrigation purposes.
Erosion control dams are governed under Colorado statute (see section 37-87-122, C.R.S. (1990). These types of structures may be constructed on water courses which have been determined by the state engineer to be normally dry (which for our purposes is dry more than 80% of the time). Structures of this type cannot exceed fifteen feet from the bottom of the channel to the bottom of the spillway and cannot exceed ten acre-feet at the emergency spillway level. The height of the dam is measured vertically from the lowest point of the upstream toe to the crest of the dam in contrast to those measured vertically from the centerline pursuant to section 37-87-105, C.R.S. (1990). Note: The structure can be larger than specified under section 37-87-122, however, it then will be evaluated and must be constructed pursuant to section 37-87-105.

科罗拉多州的《牲畜饮水池法案》第35-49-101至35-49-116节涵盖了牲畜饮水池。此类结构包括所有在1941年4月17日之后建造、位于州工程师认定为“通常干燥”的水流上的水库，其容量不超过十英亩英尺，垂直高度从渠道底部至溢洪道底部不超过十五英尺。同样，与侵蚀控制坝类似，高度是从上游脚部最低点至溢洪道顶部的垂直距离。禁止将牲畜饮水池用于灌溉目的。侵蚀控制坝受科罗拉多州法规（参见1990年《科罗拉多州法典》第37-87-122节）管辖。此类结构可建于州工程师认定为“通常干燥”（在此目的下指80%以上时间处于干燥状态）的水流上。此类结构的尺寸不能超过从渠道底部至溢洪道底部十五英尺，以及在紧急溢洪道水平面上不超过十英亩英尺。坝的高度垂直测量自上游脚部最低点至坝顶，与依据1990年《科罗拉多州法典》第37-87-105节测量的中心线高度不同。注：该结构可能大于第37-87-122节规定的尺寸，然而，它将被评估，并必须依据第37-87-105节进行建造。
