A watershed is the land area that drains water to a particular stream, river, or lake. It is a land feature with boundaries that can be identified by tracing a line along the highest elevations between 2 drainage areas on a map, often a ridge. Large watersheds, like the Mississippi River basin, contain thousands of smaller watersheds. The Ruedi Reservoir, Frying Pan River and Crystal River watersheds are part of the Roaring Fork Watershed.Water Resources FAQ
Please visit the EPA Surf Your Watershed for more information on the Roaring Fork Watershed. The Roaring Fork Conservancy can also answer many of your Roaring Fork Watershed questions -
A dry section of river can be explained in several ways:Water Resources FAQ
- Droughts can naturally cause sections of streams to run dry. If the snowpack, rainfall, and groundwater storage is unusually low for a year, or multiple years, the inputs to a stream system may be too low to sustain surface water flows.
- Legal diversions can dry up certain sections of rivers and streams. The upper Roaring Fork near Independence Pass, for example, may be dry several months of the year due to diversions that take water to Front Range communities. Other legal diversions exist, such as diversions used for pond and reservoir filling, irrigation and fire suppression.
- Illegal diversions of water are not common but can also cause the drying up of streams and rivers. If you suspect someone is illegally diverting water, please call the state engineer in Glenwood Springs at 970-945-5665.
- Depletions from groundwater wells can cause a watercourse to dry up. Much of the water in our streams is directly fed by groundwater (water from rain, snow and irrigation that flows underground before surfacing in a stream, river, spring or seep). Wells that access this groundwater essentially intercept the flow before it has the opportunity to surface. One well may not cause measurable changes in surface water, but the overall effect of many wells can dry up or significantly impact the amount of water in a stream.

Water Resources FAQ
Groundwater is managed by the Colorado Division of Water Resources. Permits are issued through the Denver office. You can get more information from the division's website. They also have a groundwater information line at 303-866-3587. Also, see the Colorado guide (PDF) to well permits, water rights and water administration.

This is typically determined by sampling and testing water from the well in question. In Pitkin County, this is the responsibility of the property owner or developer to determine. Pitkin County staff would be happy to help you understand the procedures for sampling and testing your well water. There are many independent water sampling and testing entities locally and statewide. Here is information (PDF) on state-certified laboratories in Colorado.Water Resources FAQ
There are also several options for treating well water once samples have been tested. There are many commercial suppliers of these technologies. We would be happy to discuss these options with you. -

Given the cost of water in the west, whether you are talking about the cost of municipal supply or the price of a well, many people have turned to alternative means of water supply. Water law in Colorado identifies rainwater as surface water. Usually the rights to the water falling on your roof are already held by someone in the form of a surface water right. You will have to contact the state engineer at 970-945-5665 to determine all of the necessary actions required to divert this water for your own use.Water Resources FAQ

Pitkin County and towns within the county use both magnesium chloride and sand for snow removal and dust suppression. Pitkin County continues to pursue the use of the most effective and least harmful methods of dust suppression and deicing.Water Resources FAQ
The fact is both of these applications can degrade water quality to some degree. Sand can cause sedimentation of streams and rivers, decreasing oxygen in the water and in some cases can create cementation, a process in which sand gets "cemented" between larger rocks and solidifies the bottoms of our streams and rivers. This can destroy fish spawning and feeding areas and, in turn, also destroy the recreational quality of our waters.
In terms of wildlife (aquatic life) there is no state standard for magnesium chloride in our rivers. There are, however, standards for public drinking water supplies. The Roaring Fork Conservancy has sampled many points throughout the county and has never found levels of magnesium or chloride that exceed the limits set on our public drinking water. -
Generally, no. If you hold a water right on that ditch you may be entitled to some or all of the water in it at certain times. As a starting point, you should look at your property deed to determine whether water rights were transferred with your parcel. If you do not know the status of the water rights in the ditch, you should contact either the ditch company who manages it, or the State Engineer's Office at 970-945-5075.Water Resources FAQ

The water from springs and seeps almost always requires a water right. Water rights may or may not be available for the spring or seep on your property. Contact the state engineer in Glenwood Springs, by calling 970-945-5665 for more information on your spring and water rights associated with it.Water Resources FAQ

Obtaining water rights in Colorado is a complicated process and the rights to most of the water in Colorado are already held.
For a good general overview of what is involved in obtaining water rights, associated fees, and contact information for regional water courts in Colorado see the Colorado Division of Water Resource's water rights information.

Typically, when you see a stream or river foaming, or an area with bubbles building up, it is due to naturally occurring substances in the water. These substances can originate from plants, wetlands or soils, and often cause bubbles in our steep terrain.Water Resources FAQ
If there is something suspicious about the foam or bubbles (e.g., color, odor) please call Pitkin County Environmental Health and Natural Resources. If you smell or suspect a gas leak, or believe that other hazardous materials may be entering a waterway, call 911 as soon as possible for direction. -
Water captured by storm sewer systems is not treated before it enters the river. Therefore, it is important to report anything unusual relating to water entering or leaving these structures. The most commonly recognized storm sewers, existing on city streets and major roadways, have metal grates over them. The majority of this type of storm sewer exists in the City of Aspen. Within the City of Aspen, please call Aspen Environmental Health (970-920-5039) to report any problematic activity.Water Resources FAQ
There are other stormwater drains county-wide that need to be kept free of household, commercial and industrial wastes. These include roadside ditches, stormwater catchment ponds and other ditches and culverts. If you see anything unusual in any of these alternative storm drains, please contact Pitkin County Environmental Health and Natural Resources as soon as possible (970-920-5070). -
Operating equipment in or otherwise altering a stream channel requires U.S. Army Corps of Engineers approval. If you suspect that the work being done is not an allowable practice, determine the location of the activity and call Pitkin County Environmental Health and Natural Resources, 970-920-5070, so that we may follow up with the U.S. Army Corps of Engineers' office in Grand Junction.Water Resources FAQ

If the ditch on your property belongs to you, you may move it so long as the relocation of the ditch has been approved by the State of Colorado Division of Water Resources and the relocation does not adversely affect other water users.Water Resources FAQ
If the ditch does not belong to you, you may not move the ditch without prior approval from the owner of the ditch. -
If you observe a ditch that is overflowing or broken, please contact the state engineer in Glenwood Springs by calling 970-945-5665. If you know how to contact the owner or ditch company in charge of that ditch, you should notify them as well.Water Resources FAQ
If no one is available at the above number, please contact Pitkin County Environmental Health and Natural Resources by calling 970-920-5070. We will try to assist you in contacting the appropriate parties. -
If you are a member of a homeowners' association, they may be able to provide or retrieve that information for you. The information may also appear in the records associated with your property's title insurance. The Colorado Division of Water Resources may also be able to assist you. That office may be contacted by calling 970-945-5665. Odds are, the ditch is owned and operated by a ditch company that represents several water users.Water Resources FAQ
