The general trout opener in many counties throughout California will commence on Saturday, April 29, one hour before sunrise.

Because of the popularity of this annual event with the angling public, the California Department of Fish and Wildlife (CDFW) is making every effort to stock trout in all accessible waters approved for planting prior to the season opener. Because of the increased rains this winter, CDFW expects most lakes to be open and available for fishing. However, some upper elevation lakes may be inaccessible.

Most lakes, rivers and streams have a limit of five trout per day and 10 in possession. However, regulations differ on season opening and closing dates, bag limits, minimum and maximum size limits and gear restrictions.

Anglers are advised to check specific area regulations and opening dates in the 2017-18 California Freshwater Sport Fishing Regulation booklet for regulations specific to each body of water.

In 2012, CDFW regional staff created the Eastern Sierra Back Country Fishing Guide to provide anglers with a quick, informative and accurate account of the distribution of fisheries in back country high elevation lakes. This guide does not address front country waters, defined as lakes and streams that are accessible by vehicle. Most of the lakes lie within U.S. Forest Service lands managed as wilderness and usually require back country permits for overnight use. Most back country fisheries are based on self-sustaining populations of trout and do not need regular trout stocking to maintain fish populations. The guide can be found at wildlife.ca.gov/Regions/6 (under Hunting, Fishing, Education).

Crowley Lake in the Eastern Sierra is expected to be one of the most popular opening day destinations for anglers from around the state. In past years, an estimated 10,000 anglers have turned out for the opener, and approximately 50,000 trout are caught during the first week of the season. Typically Crowley is planted with hundreds of thousands of small and medium sized trout, and because of excellent food sources in the 5,280-acre reservoir, these trout grow to catchable sizes and weigh at least three-quarters of a pound by the opener. About 10 percent of the trout caught at Crowley during opening weekend weigh over a pound and a half. These fish are from stocks planted in previous years or are wild fish produced in Crowley’s tributary waters.

Anglers are asked to be particularly vigilant when cleaning fish and fishing gear at Crowley Lake and in the upper and lower Owens River Drainage. The New Zealand Mudsnail was discovered several years ago in the Owens River Drainage, and CDFW would like to prevent mudsnails from spreading into other waters. To avoid spreading New Zealand Mudsnails and other aquatic invasive species to other waters, anglers are advised to dispose of their fish guts in bear-proof trash cans, rather than throw them back into the water. Wading gear should be properly cleaned before using in new waters.

All persons age 16 and older must possess a valid California fishing license to fish within state lines. Freshwater fishing licenses can be purchased online at wildlife.ca.gov/licensing/online-sales or at regional CDFW offices or other license agents. Anglers no longer have to display their license visibly above the waist but they must have it in their possession while fishing.
