case should not be dismissed. Any such dismissal "shall be without prejudice unless otherwise specified by the court." CRCP. 121, § 1-10(5). However, nothing in Rule 41(b)(2) or Rule 121, section 1-10 requires the court to make findings of fact or conclusions of law, irrespective of whether it has dismissed the case with or without prejudice.
III. Whether the Water Court Abused Its Discretion
Next, we consider whether the water court abused its discretion when it dismissed Streu's case. Under these circumstances, we hold that it did not.
The decision to dismiss an action for failure to prosecute lies within the sound discretion of the water court. Lake Meredith Reservoir Co., 698 P.2d at 1344. We review the water court's dismissal under an abuse-of-discretion standard. Cornelius, 202 P.3d at 569 ("A trial court's decision to dismiss for failure to prosecute ... should not be overturned absent proof of the court's abuse of that discretion."); see also Lake Meredith Reservoir Co., 698 P.2d at 1344. Under this standard, we reverse a trial court's determination only if it was "manifestly arbitrary, unreasonable, or unfair." People v. Ibarra, 849 P.2d 33, 38 (Colo.1993). It is not necessary that we agree with the trial court's decision. In re Bueno, 248 B.R. 581, 582-83 (D.Colo.2000) (explaining that under an abuse-of-discretion standard the trial court's reason "need not be one that is agreeable to the reviewing court"). The trial court's decision simply must not "exceed[ ] the bounds of the rationally available choices." Big Sky Network Can., Ltd. v. Sichuan Provincial Gov't, 533 F.3d 1183, 1186 (10th Cir.2008).
The plaintiff bears the burden of prosecuting a case "in due course without unusual or unreasonable delay." Lake Meredith Reservoir Co., 698 P.2d at 1344; see also C.R.C.P. 4l(b)(1); C.R.C.P 121, § 1-10. An unreasonable delay or lack of diligence in prosecution will justify dismissal, unless the plaintiff presents mitigating circumstances sufficient to excuse the delay. Lake Meredith Reservoir Co., 698 P.2d at 1344; C.R.C.P 121, § 1-10.
We have articulated several nonexelu-sive factors that a court should consider when evaluating a motion to dismiss for failure to prosecute. These factors include: the length of the delay; the reason for the delay; any prejudice that may result to other parties; any difficulties in trying the case that may have resulted from the delay; and the extent to which the applicant has renewed efforts to prosecute the case. Cornelius, 202 P.3d at 570 (citing Lake Meredith Reservoir Co., 698 P.2d at 1344-45); see also
Oversole v. Manci, 216 P.3d 621, 623 (Colo.App.2009) (reciting same factors).
Based on the record before us, and considering the many factors that support dismissal, we cannot conclude that the water court acted in a manifestly arbitrary or unreasonable manner when it dismissed Streu's case with prejudice for failure to prosecute. Although we may disagree with the water court, its decision to dismiss under these cireumstances dees not exeeed the bounds of its rationally available choices.
First, the seventeen-month delay far exceeded the time required to establish a prima facie case of failure to prosecute. See C.R.C.P. 121, § 1-10(8) (declaring that, before a case has been set for trial, a lack of "activity of record in excess of [twelve] continuous months shall be deemed prima facie failure to prosecute"). Our courts have affirmed dismissals for failure to prosecute following similar, and on occasion shorter, delays. See Rathbun v. Sparks, 162 Colo. 110, 112, 114, 425 P.2d 296, 297-98 (1967) (dismissing after fifteen-month delay); In re Shapter's Estate, 44 Colo. 547, 552, 99 P. 35, 37 (1908) (dismissing after seventeen-month delay); Powers v. Prof'l Rodeo Cowboys Ass'n, 832 P.2d 1099, 1108 (Colo.App.1992) (dismissing case with prejudice after case had "languished for a year" on the court's docket).
Because the opposition has established a prima facie case for failure to prosecute, Streu shoulders the responsibility to provide "a convincing explanation as to why the purported mitigating cireamstances halted prosecution over the length of the delay, and why prosecution [ean] now go forward."
