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.

科罗拉多州的牲畜用水罐受《科罗拉多州牲畜用水罐法案》第35-49-101至35-49-116款的规定。这些结构包括自1941年4月17日之后在州工程师认定为“通常干涸”的河道上建造的所有水库，其容量不超过十英亩英尺，且从河槽底部至溢流道底部的垂直高度不超过十五英尺。同样，与水土保持坝类似，高度是从上游趾部的最低点至溢流道的顶端测量的。禁止将牲畜用水罐用于灌溉目的。
水土保持坝受科罗拉多州法规的管辖（参见第37-87-122款，C.R.S.（1990年））。此类结构可建于州工程师认定为“通常干涸”（在本目的中指80%以上时间为干涸状态）的河道上。此类结构的尺寸不能超过从河槽底部至溢流道底部的十五英尺，且在紧急溢流道水平处的容量不能超过十英亩英尺。坝的高度是从上游趾部的最低点垂直测量至坝顶，这与根据第37-87-105款，C.R.S.（1990年）进行的中心线测量形成对比。注：该结构的尺寸可以超过第37-87-122款的规定，但随后将进行评估，并且必须按照第37-87-105款的规定进行建造。
