<br />
<br />From 1979-1982, the trout population of the catch-and-release area on the South Platte
<br />River was dominated by rainbow trout (5a/mo gairdneri), had a biomass as high as 667
<br />kg/ha, and 50% of the trout were> 30 cm long. The trout population of an area with
<br />standard regulations (8 trout/day) was dominated by brown trout (5. trutta), had a
<br />maximum biomass of 219 kg/ha, and only 17% of the population were longer than 30
<br />cm. The difference in trout population characteristics was attributed to the harvest
<br />rates of the respective areas. Rainbow trout were more vulnerable to angling than
<br />brown trout; age 3+ and older trout were more exploited than young/smaller fish.
<br />Catch rates averaged 48% greater in the catch-and-release area than in the standard-
<br />regulation section that had the benefit of catchable-trout stocking. The catch rate of
<br />trophy-sized trout (longer than 38 cm) was 38 times greater in the catch-and-release
<br />area than in the harvest area.

<br />Center and Economic Research Service, Completion Report 75, 53 p.
<br />
<br />Rapid suburban growth north of Denver, Colorado, has caused developing
<br />communities to expand their municipal water systems. In order to obtain additional
<br />water supplies, the cities of Thornton and Westminster have initiated condemnation
<br />suits against three irrigation companies to obtain their water rights. The three
<br />irrigation companies have a service area of about 40,000 acres--30,000 are currently
<br />irrigated. Of this land, 80 percent is class II and III, the highest classes found in
<br />Colorado. Approximately 400 farms and small tracts receive water from these
<br />companies--200 are commercial farms. Total agricultural production from the
<br />irrigated lands is about $8 million per year. Economic input-output analysis shows
<br />that irrigated agriculture contributes 561 jobs to the economy and over $4 million in
<br />net income. The cities and irrigation companies should work together to develop joint
<br />use of water rather than drying up irrigated lands for municipal water supply.
