<br />Major Water Rights Calls
<br />Major water rights calls during the winter come from
<br />John Martin Reservoir (1948), the Winter Water 1A
<br />Storage Program (1910) and Pueblo Reservoir
<br />(1962). During the irrigation season, priority
<br />calls generally originate from the senior
<br />irrigation rights, including the Colorado Canal
<br />(1890), Fort Lyon Nos. 2 (1887) and 3 (1893),
<br />Holbrook (1889), Catlin (1887), Highline (1890), Otero
<br />(1890), Consolidated (1888), and Amity (1887). The
<br />Fort Lyon Storage (1906) right may also call during the
<br />irrigation season.
<br />The available capacity for exchange between water
<br />rights diverting downstream from Pueblo to points
<br />of diversion or storage upstream from Pueblo
<br />(e.g., Pueblo, Twin Lakes and Turquoise Reservoirs) is an
<br />effective means of water resource management in the
<br />Arkansas Basin.
<br />The Division 2 Engineer acts as the Operations Secretary
<br />to the Arkansas River Compact Administration. In this
<br />capacity, the Engineer is charged with conducting the
<br />operations of John Martin Reservoir during each Compact
<br />year (November 1 - October 31) according to the John
<br />Martin Reservoir Operating Plan. This is an important
<br />component in the operation and management of Arkan-
<br />sas River Basin water resources.
<br />Implementation of the Amended Groundwater Measure-
<br />ment and Use Rules has resulted in nearly real -time
<br />administration of conjunctive use of groundwater and
<br />surface water in the basin.

<br />Wet and Dry Periods
<br />Every year, Colorado experiences at least one 100 -year
<br />flood somewhere in the state. Colorado's total flood
<br />eavg.Vear losses to date have been documented to be $4.9 billion.
<br />■Max. Vear
<br />❑Min. Year The basin's most recent flood event was April 29 -May 3,
<br />1999. The estimated total historic damages for this basin
<br />are $1.3 billion to date.

<br />Stream and Lake Protection
<br />There are 126 instream flow segments totaling approxi-
<br />mately 607 stream miles in this basin. There are also 85
<br />lakes with decreed natural lake levels. These decreed
<br />water rights are held by the CWCB to "protect the
<br />natural environment to a reasonable degree." The
<br />decreed amount for each of these instream flow
<br />segments and natural lakes is based on the flow or lake
<br />level required to maintain the water- dependent natural
<br />environment. Source: Colorado Water Conservation Board
