Flooded Wells Need Tested

With the recent flooding, there’s likely to be some compromised water supplies at the municipal and private scale. Flooded wells need testing and possibly chlorination, and there are some who are needing to look at alternative water supplies.

If you are dealing with the situation, here are some resources:

Small Acreage Irrigation Guide

Small Acreage Irrigation GuideThis guide provides information about water rights and irrigation for small acreage landowners. While the content is largely directed towards those engaged or interested in some form of agricultural production, it may also be useful for those simply interested in maintaining their yard and garden plot. This guide addresses many important questions about water rights and water use for landowners and for those thinking of purchasing land. Crop water needs and irrigation scheduling are discussed, and examples are provided to help the user with common calculations necessary for irrigation scheduling and ordering the necessary amount of water to meet crop needs. In addition, information is provided on irrigation systems that are appropriate for 5 acres or less, including pumps, pipelines, and water application options. Download guide.

Septic Systems and Well Basics

Water is a limited resource in many places in Colorado. It is important to understand how we can protect water quality and minimize our water quantity uses.

How can I protect water quality on my property?

Do you know the quality of your domestic, irrigation, and livestock water supply? WaterIf you answered no, it is recommended that you test your water. The CSU Soil, Water, and Plant Testing Lab can test your water. Components of water which can affect your crops and plants are pH, salt, sodium, nitrogen, boron, sulfate, and chloride. Refer to the CSU factsheet, Irrigation Water Quality Criteria for more information.

Analyzing your water test results:

Enter your water test lab results into the Water Quality Interpretation Tool, click submit, and get some information that will help you figure out what it all means.

Is my well water at risk of contamination? Take the self-assessment to find out.

Private Well Protection Checklist Yes No
• Have you had your well water tested within the last two years?
• Is your well less than 20 years old?
• Is the water table around your well deeper than 30 feet?
• Is your well securely capped and does it have intact casing that extends 1 foot above ground level?
• Is your well properly grouted to prevent entry of surface water?
• Do you mix, load, or store pesticides or fertilizer at least 100 feet from the well?
• Do you have backflow prevention devices installed on all faucets used to fill spray tanks?
• Are animal corrals and lagoons located at least 100 feet downhill from the well?
• Is your septic tank at least 50 feet from the well?
• Have you had your septic system pumped within the last four years?
• Are unused wells on your property properly plugged, sealed and abandoned according to the Construction Rules (2 CCR 402-2)?
• Are underground storage tanks removed or less than 10 years old?
• Are all fuel tanks at least 100 feet from the well?
• Do you dispose of pesticide containers, solvents, lubricants, paints, household cleaning products, and old batteries properly off-site?

If you answer no to any of these questions, your well may be vulnerable to contamination.

Consider having your water tested and evaluate how you can improve the safety of your water supply.

Why is it important to protect wetlands and areas along a stream?

A Riparian Area is the area adjacent to a surface water body. Riparian vegetation can function as a natural filter for contaminates that can runoff from surroundingProtecting Riparian areas areas. We can protect stream water quality by maintainina vegetative buffer of 50 feet to 250 feet from the water’s edge. Within the riparian buffer, limit or discontinue grazing to maintain a healthy stand of vegetation. To protect water from excess nutrients and sedimentation, do not allow animal access to streams, ponds, or other water bodies.

How Can I Prevent Water Pollution?

Water Pollution
  1. Protect Riparian Areas:
    • Create or maintain a Riparian Buffer at least 50 feet to 250 feet from the water’s edge
    • Allow very limited or no grazing within the buffer to maintain healthy vegetation
    • Plant native trees, shrubs, and grasses in the buffer area
    • Avoid storing manure or corralling animals within the buffer area
    • Use only water-safe herbicides within the buffer area

  1. Find out how much water your plants and/or crops need to avoid over-irrigating. Over-irrigating leaches soil nutrients, causes erosion, and spreads fertilizer and pesticides.
  2. Dispose of manure, bedding, and feed wastes by composting, spreading on crops, or hauling it to a composting or disposal facility.
  3. Read fertilizer, herbicide, and pesticide labels carefully and only use the recommended amounts.
  4. Properly dispose of chemicals, used motor oil, and other toxic substances. Contact your county health department.

Water Quantity

Colorado has a semi-arid climate and water is a very limited resource in many places. The average yearly precipitation in Colorado is 17 inches. However, the San Luis Valley and parts of south central Colorado receive an average of less than 12 inches of precipitation each year and many mountainous regions receive an average of 40 inches of precipitation or more each year. Do you know how much precipitation your area receives?

In addition to climate limitations, water regulations may also determine the amount of water you have available to use at a given time. Know your water rights. For example, if a ditch flows through your property, you may not have the right to use the water. Know what water uses your well is permitted for. Many rural wells are designated household-use-only which means water can be used only within the home, with no outside watering, including gardens and livestock uses. Contact the Colorado Division of Water Resources to find out what your water rights are.
