Department of. Study region The study region encompasses the Upper Colorado River Basin (UCRB), which provides water for 40 million people and is a vital part of the water supply in the western U.S. Study focus Groundwater and surface water can be considered a single water resource and thus it is important to understand groundwater contributions to streamflow.

[See Classifications And Numeric Standards for South Platte River Basin, Laramie River Basin, Republican River Basin, Smoky Hill River Basin, Regulation No. 38 () ] and [See Tables ] (Effective Febru ) Colorado's water quality standards are applicable to "waters of the State".

Forty-four river, stream, and drain sites in the Upper Colorado River Basin in Colorado were sampled during ?98 to determine the occurrence and distribution of pesticides in the basin.

In a fixed-station study, 57 surface-water samples were collected from October through January at four sites. Upper Colorado River Basin THIS REPORT summarizes major findings about water quality in the Upper Colorado River Basin that emerged from an assessment conducted between and by the U.S.

Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program. Water quality is discussed in terms of local and regional issues and. Groundwater and surface water physically overlap at the groundwater/surface water interface through the exchange of water and chemicals.

This exchange is a critical part of the hydrologic cycle. Surface water supplies recharge to the underlying aquifer, where the groundwater can remain in storage for days, months, years, centuries, or even.

SUMMARY OF DATA COLLECTION IN THE UPPER COLORADO RIVER BASIN, Study component. What data were collected and why. Types of sites sampled. Number of sites.

Sampling frequency and period. Surface-Water Chemistry. Basic fixed sites-general water chemistry. The Colorado Division of Water Resources administers water rights and interstate compact agreements throughout the state.

To administer these, the Division maintains a network of stream and reservoir monitoring sites which collect and transmit periodic data values. Pesticides Found in Surface Waters.

Past studies have detected pesticides in surface waters in all regions of the nation. Of the hundreds of pesticide compounds that have been used in the United States, however, only 98 pesticides and 20 pesticide transformation products were included as analytes in the reviewed studies.

the Basin Plan) for the Colorado River Basin Region was prepared by the California Regional Water Quality Control Board, Colorado River Basin Region, in accordance with criteria contained in the California Porter-Cologne Water Quality Control Act, the Federal Clean Water Act, and other pertinent state and federal rules and regulations.

The Colorado River flows from Dawson County to Matagorda Bay and the Gulf of Mexico. The second longest river in Texas, the Colorado River is only the sixth largest by average annual flow volume. A large portion of the basin is located within relatively arid.

The Mexican Water Treaty of - Committed maf of the river's annual flow to Mexico. Upper Colorado River Basin Compact of - Created the Upper Colorado River Commission and apportioned the Upper Basin's maf among Colorado ( percent), New Mexico ( percent), Utah (23 percent), and Wyoming (14 percent); the portion of.

About The Basin Plan. The Water Quality Control Plan for the Colorado River Basin (Basin Plan) is designed to preserve and enhance water quality in the Region and to protect the beneficial uses of all regional waters for the benefit of present and future generations.

The Colorado begins at La Poudre Pass in the Southern Rocky Mountains of Colorado, at 10, ft (3, m) above sea level.

After a short run south, the river turns west below Grand Lake, the largest natural lake in the state. For the first miles ( km) of its course, the Colorado carves its way through the mountainous Western Slope, a sparsely populated region defined by the portion of.3.

Major quantities of organophosphate and carbamate pesticides are used in the irrigated lands adjacent to the Lower Colorado River below Parker Dam. 4. There are several possible ways that contamination of surface waters by pesticides may be occurring in the Lower Colorado River.

5.Although agriculture and urban activities have substantially affected water quality in several areas of the South Platte River Basin, concentrations of pesticides and volatile organic chemicals (VOCs), such as MTBE, are generally below levels of concern for human health, according to the results of a 5-year investigation of water quality by the.
