Series: Colorado Water Law Basics - Impact of Tier 1 Water Restrictions
Now that Tier 1 water restrictions are in place, review the LWS blog series on the Apportionment of the Colorado River, the Colorado River Drought Contingency Plan, and a Case Study [in AZ] Addressing the Impact of the Drought Contingency Plan!
ARTICLE: Conservation Easements
Conservation easements are one way that protects the historic use of properties while, at the same time, provides significant tax benefits for landowners, based on the value of the conservation easement. Very often the largest asset that are farmer or rancher has is in their water rights…
Numerical Groundwater Flow Modeling, Part 4
In Part 3 (February 2, 2022) of the LWS series on numerical groundwater modeling, we described the basic elements of the groundwater flow equation. This week’s LWS blog describes the use of model grids to describe hydraulic properties.
Article: Colorado Water Rights Valuation
LWS has extensive experience with the valuation of water rights, including direct flow surface water diversions, storage rights, and alluvial and bedrock aquifer well water rights. As detailed in our September 7, 2021 blog, it is a multi-step process to conduct the technical aspects required to then value surface water direct flow rights. The legal aspects related to valuing water rights is described in detail in the attached article
Groundwater Flow Modeling - Methods
A model of any natural system is a simplified representation of that system. Groundwater models incorporate parts of the hydrologic cycle that effect groundwater. A groundwater model is a mathematical representation of a groundwater flow system. There are three main types of groundwater models…
The Need for Groundwater Monitoring Systems
A groundwater monitoring system is typically a series of wells completed into one or more aquifers, depending on the objectives of the system. Groundwater monitoring systems are installed for many different purposes, generally including evaluation of groundwater water quality and water levels. The monitoring can be in one aquifer, one stratum within an aquifer, or could be installed to monitor multiple aquifers.
Article: Colorado River Basin Drought Conditions
LWS blogs on May 4 and May 11, 2021 discussed the apportionment of Colorado River water, under the Colorado River Compact and the Drought Contingency Plan, that would be implemented as levels in Lakes Mead and Powell decrease. Now, a year later, the situation in the Colorado River Basin is not improving. The attached article highlights some of the issues facing Lake Powell as a result of the ongoing drought conditions in the basin.
Packer Testing Methods and Purposes
Borehole and aquifer testing is an essential part of characterizing the underlying hydrogeological conditions at various project sites in many Lytle Water Solutions projects. The packer test is a widely-used method to determine in-situ (i.e., in place) or localized hydraulic properties of formations, especially in boreholes intersecting various rock units or multiple water-bearing strata within an interbedded formation. Open hole water levels and other forms of testing cannot provide the detailed aquifer hydraulic properties of individual horizons that can result from packer tests.
Analyzing Water Quality Results
In the LWS March 3 blog we discussed the methodologies for the collection of representative water quality samples. The follow-on question is how do we analyze these data? There are a number of methods for evaluating water quality depending on the parameters and what you are trying to understand. Do you want to know if the sample complies with Safe Drinking Water Act because the water is going to be used for potable purposes? Do you want to know the type of water so you know its applicability for certain uses? Do you want to know if the water has been contaminated with certain constituents? Each of these questions is addressed in a different manner.
Article: A Win-Win Scenario for Urban/Rural Water Supplies
Bruce Lytle, President of Lytle Water Solutions, co-authored an article that provides useful information on innovative means to more efficiently grow crops, while at the same time using less water. LWS helped pioneer an aspect of more efficient methods to irrigate crops in an intensive 3-year study in collaboration with Colorado State University and the Parker Water and Sanitation District. The link to the article, published in The Water Report, is provided HERE.
Collecting Water Quality Samples
Why do we collect water quality (“WQ”) samples? There are a variety of reasons…At Lytle Water Solutions we follow standard field protocols and procedures established by the U.S. Environmental Protection Agency. Of utmost importance in collecting groundwater samples is that the samples collected are representative of the groundwater aquifer and that the samples are collected, stored, and delivered to the analytical laboratory in a manner to not contaminate the samples.
