Pearl River Valley Water Supply District

Last updated

The Pearl River Valley Water Supply District (PRVWSD) is a governing entity within the state of Mississippi tasked to manage a portion of the Pearl River basin, including the Ross Barnett Reservoir area, and its watersheds. The responsibilities of the district include: overseeing land management, maintaining natural resources, and providing recreational opportunities.

Contents

History

In 1956 the Pearl River Industrial Commission was authorized by the Mississippi State Legislature to study the feasibility of development along the Pearl River basin near Jackson, Mississippi, primarily the creation of a reservoir through the construction of a spillway and dam. A hearing on the proposed development was heard by the State Board of Water Commissioners, as well as the Boards of Supervisors within the proposed district, and found that the project was a public necessity to compensate for the increasing demand for potable water (PEER report #471, 2004, page 3). As a result of that finding, the Pearl River Valley Water Supply District (PRVWSD) was created in 1958 to oversee construction and future management of the Pearl River Reservoir (later named the Ross Barnett Reservoir), its watersheds, and surrounding land. The reservoir project was completed 1965 following the construction of an impoundment of the Pearl River bordering Rankin and Madison counties. [1] The funding for the reservoir's construction was secured through bonds, which were to be paid off, in part, by taxes collected from municipalities within the newly formed district, as well as the city of Jackson, which would be drawing drinking water from the reservoir. The construction bonds were paid-off in 1992, and, since that time, the district no longer collects taxes, [2] rather relying primarily on annual lease fees from residential and commercial properties within the district for funding. [3]

Governance

The PRVWSD is tasked to govern a 45-mile-long water basin comprising the Ross Barnett Reservoir and portions of the Pearl River, as well as land within one-quarter mile from the shoreline. Counties with land in the district are Hinds, Leake, Madison, Rankin, and Scott. [4] The district operates on a committee system, and is primarily funded through commercial and residential property leasing fees. [5] Responsibilities of the district include: [6]

Organization

The district is governed by a 14-member board as follows. [7]

Water supply and quality

The Ross Barnett Reservoir was created largely to compensate for the growing demand for drinking water in the area. The PRVWSD is tasked to maintain the environmental quality of the water supply as one aspect of their management program. Water quality tests are conducted frequently, as well as surveys of silting in the upper reservoir.

The PRVWSD also monitors and manages the distribution of invasive aquatic plants (macrophytes) in the reservoir. A five-year survey commissioned by the district, and headed by the Water Resources branch of Mississippi State University, studied the environmental impact of invasive plants in the reservoir. The survey identified fourteen invasive aquatic plants, Alligator weed being the most prevalent. [8] The PRVWSD utilizes a number of methods to control the spread of invasive plants, including public education programs and the spraying of EPA approved herbicides. [9]

City of Jackson

The Ross Barnett Reservoir serves as the primary source of drinking-water for Mississippi's nearby capital city, Jackson. [10] [11] A 1982 lawsuit was brought against the district by the city, successfully claiming that PRVWSD misappropriated tax collections from the city for purposes other than paying off the original reservoir construction bonds, including the funding of a district law enforcement agency. The bonds were paid off in 1992, and the district no longer collects taxes from the city. [12]

Dam and spillway

The PRVWSD maintains a ten-gate spillway to control the lake level and discharge into the lower river. The steel gates are forty feet wide and twenty feet tall. The spillway is monitored 24-hours via a computer system and surveillance cameras located in the control tower situated on top of the dam. Computer software developed by the Mississippi Valley Division of the Corps of Engineers assist spillway operators in maintaining the correct discharge amount. The maximum output of the spillway is 170,000 cubic feet per second. The minimum discharge is 240 cubic feet per second. [13]

Flood control

One aspect of the PRVWSD's management program is to mitigate flood events in the district, the upper river, and downstream.

Following the 1979 Easter flood, which left much of greater Jackson underwater, a report by the United States Comptroller's office found that the impact of the flood was due largely to a lack of communication between agencies. [14] Since that time the Mississippi Valley Division of the Corps of Engineers, the City of Jackson, and the PRVWSD- as well as other involved agencies- have cooperated to develop an action plan in the event of another flood. [15] There have also been numerous, highly debated, proposals over the years for additional flood control measures, both upstream and below the dam, but specific projects have yet to be approved. [16]

Law enforcement

The PRVWSD operates a law enforcement agency within the district. The Reservoir Police patrol roadways, waterways, and commercial and residential areas within the district. They cooperate closely with other law enforcement agencies of the surrounding municipalities, and are fully authorized by the State of Mississippi to operate as a branch of law enforcement. [17] [18]

Leasing and land management

The district leases shoreline property for commercial and residential development, and relies on lease fees to provide the majority of district funding. According to the PRVWSD website, approximately 5,300 leases are in currently place. [19]

Recreation

PRVWSD manages 22 boat launches, 16 parks, 5 campgrounds, 3 handicapped accessible trails, and 2 multipurpose trails. [20] Recreation areas are used by an estimated 2.5 million visitors each year. [21] [22]

The 1979 Easter flood was one of the most costly and devastating floods to ever occur in Mississippi, United States, with $500–700 million in damages. It was the result of the Pearl River being overwhelmed by severe rain upstream. Floodwaters sent the Pearl River 15 feet above flood stage. More than 17,000 residents of Jackson, Flowood, Pearl, Richland, and other settlements in the Jackson metropolitan area were forced from their homes. The flooding of the Pearl River placed most of the streets of Jackson, the state's capital city, under several feet of water. This flood resulted from a storm system that was the same storm system that, just a few days earlier, produced the Red River valley tornado outbreak that is particularly well-known because of the devastating Wichita Falls, Texas tornado that killed 42, injured over 1,700, left an estimated 20,000 homeless, and caused, in 1979 dollars, approximately $400 million in damages.

Fannin is an unincorporated community located in northwest Rankin County, Mississippi, United States, near the cities of Jackson, Flowood, Brandon, and Ridgeland, loosely bordered by the Pearl River and Pelahatchie Creek. Originally occupied by Native Americans, the eventual settlement became a thriving agricultural-based town post Civil War, through the first half of the twentieth century. The decline of the railroads, the impoundment of the Pearl River, and the general migration of settlers toward nearby cities led to Fannin's eventual dis-incorporation and transition into a mostly rural residential community.

<span class="mw-page-title-main">Lake Hico</span> Cooling pond reservoir in Jackson, Mississippi

Lake Hico was a cooling pond reservoir built on 16th section school land in Jackson, Mississippi, in the 1950s. Its primary purpose was to provide water for the adjacent Rex Brown Plant, which generates electricity with steam. Initially, Lake Hico was open to the public for recreation. The lake was closed to the public in the late 1960s, along with the public swimming pools in Jackson, due to racial prejudices preventing peaceful integration of public swimming holes. Lake Hico was built as a cooling lake for the Rex Brown Electric Generating complex. Part of the agreement with the Hinds County board of supervisors was to have a public recreation lake and a lake for the intake and the exhaust of water for cooling for the generators. Thus the two lakes. It was originally built as a fuel oil based generating system but was later converted to natural gas when oil got so expensive in the 1970’s. The reasons why it was finally closed to the public were 1- the Barnett Reservoir opened and most people who had formerly used the lake went there and 2- the liability costs to MP&L skyrocketed after there was a couple of drownings. The fact that integration of such public spaces was being attempted by some and resisted by others in Jackson, Mississippi at the time is possibly pertinent. The adjacent Hico Park was closed after a lawsuit to integrate that park was filed as late as 1975. The Rex Brown plant was just recently totally dismantled.

<span class="mw-page-title-main">Jackson, Mississippi, water crisis</span> 2022 water crisis in Jackson, Mississippi, U.S.

A public health crisis in and around the city of Jackson, Mississippi, began in late August 2022 after the Pearl River flooded due to severe storms in the state. The flooding caused the O. B. Curtis Water Treatment Plant, the city's largest water treatment facility, which was already running on backup pumps due to failures the month prior, to stop the treatment of drinking water indefinitely. This resulted in approximately 150,000 residents of the city being left without access to safe drinking water. Mississippi Governor Tate Reeves issued a state of emergency and United States President Joe Biden declared a federal disaster to trigger federal aid. Reeves withdrew the state of emergency on November 22. The crisis triggered a political debate regarding racial discrimination, infrastructure neglect, and shifting local demographics.
