JAMESTOWN, N.D. (NewsDakota.com) -Known as North Dakota’s premier crappie fishery, Jamestown Reservoir recently underwent its annual assessment by the North Dakota Game and Fish (NDGF) Department. Conducted in mid-to-late May each year since 2008, this survey gathers critical data to help manage the popular fishing spot.

“This time of year, crappies are shallow, making it easier to collect data on growth rates, length, weight, fish condition, and sex ratios. We also differentiate between white and black crappies,” explained BJ Kratz, NDGF fisheries supervisor.

The fisheries crews use trap nets for their survey, setting them in eight locations for two days before retrieving and measuring the fish.

The quality and quantity of crappies in Jamestown Reservoir have improved significantly since fish limits were introduced in the early 2000s. “We initially set the limit at 35 in 2002, reduced it to 20 in 2006, and then to ten in 2014. This was based on data showing good survival rates but poor recruitment. While crappies spawn successfully each year, many don’t survive their first winter,” Kratz noted.

The lowered catch limits have made Jamestown Reservoir a more stable fishery, avoiding the previous boom-and-bust cycles. The reservoir’s unique environment also contributes to its success. “In the summer, the reservoir produces a lot of plankton, which is great for smaller fish. However, growth rates slow after about age six because larger fish need more substantial forage. Additionally, the reservoir has excellent spawning substrate,” Kratz added.

Although ice fishing is popular in winter, late spring and early summer are also prime times for crappie fishing. “In May and June, crappies move into shallow waters, making them easy targets for shore anglers during their spawning season,” said Kratz.

This year’s survey found a healthy population of crappies, with many measuring between 10.5 and 11 inches, solidifying Jamestown Reservoir’s reputation as a top crappie fishing destination.
